Multi-Threaded optimisation for Il2 and VR

[TUS_Samuel]

Once again. Task manager shows correct average load.

Of course registry tweaks cannot make thread run faster then single core allows but 78% average CPU load on 4 cores looks too high for il-2. I've never seen such a high load in reported measurements.

Maybe last update + high settings + low 7700HQ frequency gives this 78%. However there is no point to argue without benchmarking.

I like my magic?

 

On a side note, Pimax has released their BrainWarp Software in Beta with a new PiTools update.

Now running PiTool render at 1, BrainWarp at 64Hz with smoothing on, Normal FOW (150 Degrees)

SteamVR render at 50%

Il2 Balanced with high shadows and clouds with terrain distance at 100km and detail at x4

 

Flying smooth in QMB with overcast sky and targets trying to shoot me down.

 

They have also improved their lens distortion profile and it is especially improved on the Vertical.

 

As for conventional tests, they are geared to Gen 1 devices and hold little relevance to Gen 2 HMD's  I am sure there is plenty of people out there with i7 7700 CPU's and 1070 cards who have done those benches.

Hello and thank you for pointing us to these tricks. I have a question maybe someone could shed light on. In the one guide it talks about pagefile size and says to set it to 4096. It also says to set it to 1.5x the total ram in pc. Well if I have 16gb, that math is not making sense. Would it mean that the guides maker has like 2gb ram? Is there something else here? Are we suppose s to do this for is hard drive or game hard drive if they are separate? Thanks.

 read this: https://www.howtogeek.com/126430/htg-explains-what-is-the-windows-page-file-and-should-you-disable-it/

There is also a nice explanation from Microsoft so here pure facts, only I can not find it any more. 

 

But why not test it by your self?????? 

[SShrike]

Thanks 

I will test it but I was just curios of the lack of clarity being that a specific number was to be inserted that didn't seem to reflect any specific ram specs is all. If 1.5 times the pc ram is to be put in then 4096 is way low for 16gb. Was just trying to gain clarity is all

Most of all that tweaking stuff you read is an copy/paste from XP and does not have an to be measured impact in Windows . Same as register cleaning, or set “prior GPU to 8”  here the source from Microsoft as a sample.

GPU Priority

REG_DWORD

The GPU priority. The range of values is 0-31. This priority is not yet used

But if you feel a setting is working, like some see the GPU priority is working, then go for it. It is still a computer and computers can act very strange, but try to measure.

Disabling Hyperthreading in the CPU.

 

Just did that and have not noticed any difference. i7 8700K overclocked to 5.0

[Guest deleted@134347]

disabling HT

registry changes

nvidia priorities

 

all of that resolved 16 plane furball ghosting in Berloga for me on vivepro (medium, med shadows). 

 

however Kuban is still heavy.

If nothing else it should lower your CPU core temps.

Mine was on Auto in the BIOS.

Disabling HT should enable you to increase OC *if you are temperature limited*.

 

You could disable HT, then see how far you can push clocks and save that as a different OC preset. I would expect you attain slightly higher FPS by running higher clocks like that.

 

But you should definitely see a decrease in CPU temp withou HT.

[WB_jokkr]

OK, I don't know if this helps but

 

I've been playing solely on the original BOS. I've tried everything I could find to improve my experience. Some were  snake oil, others made a difference.. Not so much frame rate but clarity. I seemed stuck in the 40-50 fps  level. I did notice when I made a change it initially appeared to help, but as the game loaded the processor it would go back to the old experience.

 

Today, I said Fk iT and downloaded Kuban, It overwrote everything so I spent the afternoon getting all my settings back up.

 

So on high settings with decent graphic settings, ground medium, clouds high etc I took my first flight.

 

Holy shit batman, My fps jumped significantly. With the HUD off I was actually seeing 90fps for the first time, Average was 75+ fps in single mission. HUD does hit the framerate hard, but I was still averaging 20fps better than before.

 

More importantly, with largely the stock setting I could SEE. Airplanes were now not only visible but the detail was far better and I could see the aircraft type. I could even see the props of the other planes a ways off.

 

OMG. If your dealing with low fps in VR with a capable rig, try a reinstall. I don't know if there are improvements in Kuban, not present in BOS but for me it worked out .

 

For fun, I did 1v4 against the IL2, me in a FW. I'm knocking the crap out of them, parts flying off on every pass. Seemed almost invulnerable,  eventually the rear gunner would get my engine. Did they change the damage model?

A reinstall may have brought any fragmented files together helping performance.  As far as the game itself goes, you already had the whole game.  All buying a new "battle" does is allow you to fly the aircraft for the battle (unlocked) and to use the map off line.  All maps are available in on-line servers.

Its already overclocked to 5.0Ghz and very stable, so dont want to push it more than that.

Will give it another try.

[WB_jokkr]

I would have thought the same, but the install was huge and overwrote a number of files (D3x etc) that I would not have expected for a battle upgrade.

5Ghz is almost the highest speed of todays CPUs. Given that i get drops down into the 40s in career mode, OC another 100 or 200mhz wont make any difference. The cause for the high CPU demand should be adressed, no screwing CPU clocks up into impossible numbers.

Considder a complete fresh OS install, or better get an extra m2 SSD only for IL2.

Great idea, this one (256GB) is getting crowded.

 

Thanks

Waiting for Chiliwili to report back

 

Finally I could have some time to test this register trick.

I already had HT disabled and Maximun performance in Window power option.

 

For the registers:

Changed SystemResponsiveness from 14 (Hex) to 0

GPU Priority was already at 8

Priority from 2 to 6

Scheduling Category from Medium to High

 

I run the IL-2 VR benchmark with different SteamVR SS.

The solid lines are before the change. The dotted lines after the change. So I can conclude that there is no gain in my system:

 

 

Thanks to the benchmark we can build some science around this tricky world of feelings.

 

Thank you anyway for always looking potential ways to increase performance but this one doesn´t work for me. 

We always have to be open to the most strange theory, but as Carl Sagan said "Extraordinary claims require extraordinary evidence"!!

 

[Dutch2]

Guess we need a ghost in the magic lamp for 50+ FPS ?‍♂️
