Measuring rig performance: Common Baseline (for IL-2 v3.010)

[A_radek]

I also find it strange your il2 fps went down with the oc, especially after passmark verifying a performance increase and that you got it all right.

 

But if the current settings give you the higher performance in il2. Keep them!

 

As I understand it the Intel turbo will bump only one core at a time to 4.5ghz. While that oc you tried allowed them all to go there.

 

In your cpu-z screenshot, It's showing the speed of core #0, right click that value and you can see them all and at what speed they are running. You can probably have that open while running the benchmark. Though it could affect performance results.

 

If you want to dig deeper in to it all, this is a very good guide for everything you would want to know regarding your Asus bios and the 7700k overclocking.

Thanks for the tip and info.  I checked by right-clicking in CPU-Z and it showed all 4 cores running at 4.5.  I'll take a read in that guide and see what I can figure out.

 

In the meantime, I ran another QMB with IL-2s vs. Ju-52s last night - forgot to turn on Fraps beforehand, but it was amazing looking and felt very smooth with no hint of motion sickness/discomfort.  Downed 3 of the 4 Ju-52s and damaged the 4th before running out of ammo - hung around to watch my AI buddies try to take out the 4th one, but saw him make it back to land at his airfield trailing fuel and smoking all the way back.  Then I managed to find a friendly airfield and land my IL-2 almost perfectly (ran about 15 feet off the end of the runway 'cause I hadn't remembered to assign brakes to anything when I re-arranged my controls for VR use).  After all these years of waiting for BoS to get to the point of my being able to enjoy it, these last couple of updates and the acquisition of my Rift have really done the trick.  I knew it would happen eventually, and with BoK and career mode almost here it'll just keep getting better and better - can't wait!

Exactly. VR is really a game changer for BoS. It simply makes you believe you are inside the plane, even if resolution is not perfect it is enough for many of us.

I remember the first time someone shot me while flying, I could even feel the bullets in my body!. I was much more afraid of being shot that in a monitor.

After missions in VR, when you remove the Rift, you have the feeling of have been in a real war scenario, being part of it.

[chiliwili69]

 

 

Chiliwili, this thread was your initative and you did 99% of the work here. I can help out with the monitor test if needed (benchmark procedure would be simpler) And I do think it would belong better as a sister-thread in the general hardware forum, with a link to this one

 

No, I have just thought it would be great, and then Balapan did all the work and shared the test that we re-used to create the procedure. The work is done by the community, contributing with their test to help decide others with their upgrades. We all just want to spend the right amount of money for a pleasant experience, but no more. 

 

I have added the monitor procedure at the bottom of the first post. You can run the test now in VR and in monitor.

 

Thank you for your contributions.

Amen to that!

 

I am currently flying Ivan's War Campaign, and having a blast. Flew a mission protecting some IL-2's, and had to engage some pesky 109 F4's that did not want to see the IL-2's make it to target.

 

I was behind one , he was banking left and I was laying cannon rounds on his left wing, that thing snapped off and went tumbling over my head and found myself trying to duck LOL.

 

When I made it back to my airfield I found myself opening the canopy to try and get some fresh air.

 

Man, flying in VR is so awesome.

Can you guys help me with a little consensus regarding the other graphics settings that work best for you in VR?

Specifically cinematic camera on/off, SSAO on/off, HDR on/off, grass setting, distant view setting, AA on/off, overall graphics quality setting (low to ultra), SS setting, vsync on/off,

and anything else along these lines. The VR section of the forum has been extremely helpful for me for various settings, but i am having a hard time compiling the consensus of these settings in one place.

 

My system is Intel I-7 7700, not overclocked because I don't know what I am doing with that, 16 gb RAM, EVGA 1080, oculus rift, Windows 10 64 Bit.

 

What has worked for me has been cinematic camera on, SSAO on, HDR on, ultra grass setting, 4X distant view, AA off, graphics quality ultra, SS at 1.1, ASW off, vsync off.

I get a smooth appearance at these settings, but it is a little less smooth at SS 1.5 even if I turn graphics and other features to lowest settings.

Sometimes, even if I get a slighly higher framerate with lower graphics settings with SS at 1.3-1.5, the overall appearance seems smoother at SS 1.1 with the ultra settings in everything.else.

I just want to optimize what I have, which I feel is a good system, but I want to draw on you guys' experience to get the most out of it.

 

Thank you for your help!

If that works best for you, then you should probably stick with it.

 

Personally, I keep cinematic camera, SSAO and HDR off (with my monitor as well as with VR), because I don't like the way it looks with them on.  Also, I run AA=4 and SS at 1.7 (in SteamVR settings), because I hate jaggies and shimmering and that looks best to me and my new rig gives me good results at those settings.  Otherwise, I'm with you on ultra grass setting, 4X distant view, graphics quality ultra, ASW off, vsync off - it looks better to me that way and it doesn't seem to exact much of an FPS penalty compared to lower settings, at least on my rig.  Screenshot of in-game graphics settings is below:

Thank you Wraithzit, added to the sheet. Your avg fps is very much aligned to the one I had when I used 1866MHz memory. As you might have read form this thread, I also had a 4790K@4.7GHz with 1866MHz RAM, then upgraded the RAM to 2933MHz and I increases 8 fps my average. a_radek and Ganeshka were also reporting nice increments in fps when going to higher RAM speeds.

My system is Intel I-7 7700

 

Is 7700 or 7700K?

 

OC is only possible with 7700K.

 

If it is 7700K you will benefit a lot going to higher clock speeds. I also thought OC was going to be very complex, but with the MSI Command Center was very easy. You only need a good CPU cooler and spend a couple of hours reading the guides. There is a thread in this forum about that.

 

 

SS at 1.7 ( set in Oculus Tray Tool).

 

So you mean SS=1.7  (in OTT), which is equivalent to 2.9 SS in SteamVR?

 

Or you mean SS=1.3 (in OTT), which is equivalent to 1.7 SS in SteamVR?

I think MSI Command Center would only work on MSI Motherboards, but not sure.

If you have another MoBo manufacturer like ASUS or Gigabyte, they also provide similar tools to do OC.

 

In any case, I will be curious to know what benchmark you achieve at 4.2GHz and once it is OC'ed. 

[chiliwili69]

 

 

1.7 in Oculus Tray Tool.

 

Yeah!, you have to amortize your GPU! 

 

I saw that initially you used 1.3 or 1.5, but with the new GPU went to higher SS.

 

I think that, once the CPU/RAM delivers a good benchmark (let´s say above 80 in this VR IL-2 benchmark) at SS=1.0, then people can increase their SS until the fps dramatically drops.

 

For my 1070 card that limit is around 1.4 (in OTT, or 2.0 in SteamVR), but I will do some more testing when to determine that.

 

Have you tried to run this benchmark with your upgraded rig?

While we already have benchmarks on higher end cpu's. The more interesting ones are from the older rigs.

 

My guess is many if not most are running things like Sandy bridge (i5 2500k) And are shying away from VR as they don't feel like replacing a perfectly good gaming computer only to try it.

 

My second guess is that those older CPUs, especially overclocked and with some faster ddr3 would do perfectly fine. But we can't really know until we have the numbers.

As Radek indicated it is also important to have benchmarks for mid-range PCs with low-med-top GPU, and also top-range PCs with low-med-top GPU.

Now my IMHOs

 

Balapan's track is good to compare rigs, but I suppose track is lacking of physical calculations. In online battles at Berloga server FPS almost never locks at 120 (I have 144 Hz BenQ running at 120 Hz) with frequent drop downs to 60-70 and this is with medium settings, unlike in benchmark.

 

There is no current hardware which allow locking FPS at 120 and playing with low motion blur displays

 

Obviously, CPU single thread performance is bottleneck. CPU manufacturers cannot improve this much due to physical limitations. Multi-core is our present and future.

 

IL-2 is indeed multithreaded but there is one thread which works most of the time and limits overall performance

Edited August 16, 2017 by TUS_Samuel

[AceVenturi]

Finally got round to Ryzen benchmark. I think something's very odd with my system as my performance should be much higher and my CPU utilisation on the most-used core sits around 40-60% while GPU is at 30-50%. I'm downloading the IL2 game standalone so I can test without Steam version.

 

Chilli, my old I5 4670K benchmarks were totally wrong, I wasn't using FRAPS correctly so you can ignore them.

What's odd is that in-game I've seen a massive improvement, often even getting 90fps taxiing and most of the time in the air and drops to 45 are normally only flying close to ground or with lots of AI/Players around. (Low graphics)

 

So I'm stumped really. The experience is much better than with my I5 but benchmark says otherwise. My GPU is not remotely being utilised (40% avg) and CPU is hardly being taxed (50% avg) so why isn't the game pushing my hardware? It's like I've got throttling turned on somehow.

I've had the same with my 1600x at 4.0 GHz and a GTX 1080TI. BoS just will not run at 90 FPS despite everything being below 50% usage in the Balapan track. In actual play, it will hit 90 fps at times when up off the ground a little but even then, it's mostly 45. Passmark single thread rating is ~2130. Other games aren't a problem and the really weird bit is DCS actually runs  better for me in VR than BoS does. That's one hell of a reversal from 2d results.

[chiliwili69]

 

 

Balapan's track is good to compare rigs, but I suppose track is lacking of physical calculations.

 

Many thanks Samuel for running this with several GPUs! (BTW, how do you have so many GPUs and no VR?)

 

Congratulations also for your good single thread performance with the 3770K, it is well above average tests.

 

This test doesn´t take into account the online playing, since this depend very much on the online servers, internet bandwidth, etc. We just wanted to analyse this from the user PC side.

 

As you guess, there is one thread of IL-2 which is the one responsible for the overall performance. Splitting this thread in multiple threads would not be an easy task.

 

Fomr you test I clearly see that GPU budget doesn´t translate to more fps. It is wiser to spend that budget in CPU/RAM.

 

Also, if you can try your rig in VR, you would obtain about 70-75 avg fps in the benchmark (just a ballpark rule of dividing by 2 the monitor performance)

I have taken a closer look if the graph you showed. 

 

Normally the fps is in the 140-160 fps range, and the 3 cards show almost the same performance. So CPU is bottleneck.

 

Only when the balapan track show no planes or smoke, the fps rise to 190-210 range and here GPU is bottleneck, so every GPU separate from the other.

 

And then, there is a general big drop when the last bomber is damaged and fire/smoke appear massively on scene. Here only the 1060 lose the trail of the other three cards.

 

I think the Balapan track was created with all sort of things (clouds, stalingrad map, multipleplanes, maybe turbulent wind, etc). I will ask him how it was created.

[A_radek]

Also found Dons result peculiar. So tested running 1.3 in tray tool instead of 1.7 in steam and got a significant drop in fps. Did not doublecheck resolution in occulus monitor, and was testing other things at the same time so can't be sure all was correct. Will investigate further another evening, short on time for a few days now.

[dburne]

Another thing I have found since installing Fraps I now have severe mouse lag when I first launch BoS. Upon getting to the log in screen, it will take around 2-3 minutes before my mouse becomes responsive - whether Fraps is running or not.

 

Going to uninstall it and see if that corrects the issue.

[dburne]

Ok uninstalled Fraps, mouse behavior back to normal now whew.

[TUS_Samuel]

IL-2 is indeed multithreaded but there is one thread which works most of the time and limits overall performance

 

Here is an illustration

 

 

You can see all IL-2 threads on this graph while playing back Balapan's track. Green at the beginning is track loading, does not matter. Then it goes actual playback, red graph shows about 90% CPU usage by the bottleneck thread with maximum peak at 98% (around the last He-111). 

 

Also you can count total CPU usage from this by summing average CPU usage and dividing by core count. In my case it is (90% red + 20% purple + 10% green + 10% other) / 4 cores = 32% which corresponds with task manager.

 

That's why you see only 30-40% total CPU usage, while FPS is low

[chiliwili69]

I added a link (Passmark test) to the procedure, so people can also report their individual passmark scores.

 

BTW, there are a page where the Single-thread CPU are sorted:

SAMUEL!!  Thank you for unveiling something that everybody was suspecting but didn´t proof with data.

 

It was always the typical complaint (CPU is not loaded!) that we had (including myself).

 

Just curious, what tool did you used to obtain and record that data?

[TG-55Panthercules]

The discussion in another thread about GPU upgrades for VR (here: https://forum.il2sturmovik.com/topic/30567-gpu-upgrade-advice-vr-please/  ) got me curious so I went in and ran another test on my 7700K - ST passmark result of 2647, running at 4.2 (I think - can't tell if it's running in turbo mode (4.5) or not - CPU-Z seems to think it is, but Passmark seems to think it's not) - I decided to make one more try at OC'ing to 4.5 and see what happens.

 

Tried using the ASUS utility that came with my MB to OC my CPU - it runs a series of iterative overclocking attempts in .1 increments, and got it up to 5.0 before I stopped it.  Ran a new Passmark test at 5.0, and the ST index/result jumped to 2937.  Then I decided to run another test with the VR benchmark (from 1st post above) to see if there's any practical benefit at this level.

 

Surprisingly (to me), the test on the VR benchmark (from first post above) with my CPU OC'd to 5.0 did not result in any improvement at all compared to running it at stock (either 4.2 or maybe 4.5 turbo - can't tell whether turbo was used or not) - actually a slight reduction at 5.0, but so close as to be within the realm of standard deviation.  But if it's correct, it would seem to indicate a point of significantly diminishing returns to overclocking CPU at this point.  

 

Really curious as to why there wasn't at least some small but noticeable improvement from such a large overclocking.  Didn't notice any unusual fan activity or temperature spikes so I don't think there would have been any throttling kicking in, although I don't know enough about how all this OC stuff works to be sure about anything at this point.

Looks like Performance monitor in Windows. 

 

I did what I thought is the same test using %processor time and got these two results, one with screen test and one in VR.

 

In VR my most used thread only gets to 60% average whereas on screen it goes up to 75% average. Weird but in either case it's not maxing out the CPU.

 

Samuel what counter did you use in Perfmon to get your graph?

Edited August 17, 2017 by AceVenturi

[TUS_Samuel]

0. This is perfmon. It is a windows utility. You can run it as simple as press Win+R and type perfmon, press Enter.

 

AceVenturi, try this

1. Run IL-2 and minimize

2. "Add Counters" -> "Thread" -> "% Processor Time" -> type "IL-2" in textbox -> select all thread instances -> click "Add"

 

Difference is that on your 8 graphs there are usages of each core and on my graphs there are CPU usages for each IL-2 thread. However core usage is also a very interesting information.

 

Below is just my interpretation and only devs can say exactly what is happening. However

CPU load in VR may drop due to a fixed time at which a frame should be ready. If a frame could not be delivered on time then it gets ready whithin next time frame and CPU sleeps for the rest of time. This cannot happen on screen because FPS is not limited and as soon as CPU delivers previous frame it starts processing the next, this gives full CPU utilization.

You can try changing pre-rendered frames in NVIDIA control-panel and see what happens. I think core utilization should be higher and FPS may rise in VR.

Thanks. Have updated and made two new graphs.

 

I tried changing pre-rendered frame settings but just got lots of tearing and lower frame rates. Setting of "1" offered no tearing but also no FPS improvement.

 

The graphs are very similar to the per core graphs but obviously without the extra 'noise' from the other cores. The VR thread does move with the same spikes as the screen version but seems to average about 60% vs 80% so about 20% lower CPU utilisation in VR.

 

I'm no programmer but what you suspect is probably right, low frequency CPUs can't deliver the frames in time leading to overall lower FPS. This explains why the person who got to 5GHz didn't see any improvement over say 4.5GHz as once the frequency is high enough the load probably shifts back to the GPU.

 

Now what would be interesting to see is what CPU speed we need to get max frames possible.

 

I was going to try overclock but someone else with a 1600X at 4GHz wasn't able to get any improvement so I suspect a 'full' frame rate isn't possible on anything lower than say 4.5GHz which puts it out of reach of Ryzen owners. Other VR games run flawlessly but BOS unfortunately does not.

 

Do IL2 Devs look at these threads? It would be good to work with them to see if we can find a way to make BOS work well in VR on lower clocked CPUs.
