SSAO, HDR and improving performance?

[No_85_Gramps]

Something that did alleviate a bit the frame rate is disabling threaded optimization on nvidia control panel. Frame rate doesn't juggle around like crazy and feels somewhat improved with less stutters.

I left the Nvidia global setting on "auto" but for the game, as a test, I turned if off. What a HUGE difference this made in stabilizing FPS and it seems to have cut down on the occasional micro-stutters. If you have an Nvidia card you need try this out.

I think the game doesn't run well on multi-threading.

That's sounds interesting. I have always had threaded optimization auto or on. Never occured my mind to change it off. Maybe it will get rid off annoying micro stutters. Testing after work.

I will give it a go also and see what happens. Thanks.

No improvement for me after quick testing unfortunately.

Just an update on this. I did some more testing and have determined there really was not much, if any, difference on my machine. Don't know how I came to the conclusion I originally did...maybe just wishful thinking on my part. I'm still happy with my current settings as they rarely dip below 40 FPS and with little activity hit 60 FPS. This on an I5 4690K at 3.9 Ghz with 12 megs of ram and a GTX 750TI. And before anyone mentions it, my motherboard does not support overclocking, I just run it max speed. (The K version was cheaper at the time I purchased it.)

I believe, and my point of view, actually in missions where we have many objects, the CPU works more and have a drop of FPS.

 

easy test: go to campaign or generate mission with many objects, then go to Quick Mission and put only your plane and the enemy. FPS big difference both as Stuttering

I really do not understand the amount of difference between my Sandy Bridge cpu against others from the same generation and newer. Puzzles me the lack of performance I get with this game. All in all, at 99% of games there's hardly difference between the Sandy Bridge and the Haswell refresh chips. A few percent up and down. It's really weird.

[Dakpilot]

Maybe it is worth downloading and trying one of the popular 'syntheytic' benchmark tests and comparing the results to give you an idea if you are getting the correct performance, there should be plenty of data available for sandy bridge

This is a test many use, it is payware though. But it seems to be a standard. Look at the single core score for BoS

This is an easy and free CPU comparison website, once again look at Single Core Performance

Thanks for the tip, man. Haven't thought about running benchmarks to pin point the issue. Silly me.

 

Ok, my score is within the i5 2500k range on CPU Boss results:

 

Single Core: 1793

Cpu Mark: 6405

 

That's actually not so much slow than a higher price Haswell i7. Around 18%. Kind of lost now. I think the game just hate me.

 

Only thing out of ordinary I've noticed on my system was the main disk performance, kind of slow. But it's not the same disk I have IL-2 Bos installed. That one is actually fast for a mechanical drive.

Ok, this might sound weird, but looks like Single Thread performance might be improved by disabling all sound devices you're not using on Window Sound panel. I've left only my Audigy soundcard on and got a 10 fps improvement. Still not quite smooth against ground targets, but far better than before. Aerial combats have an average now of 50-60fps.

Some tips for squeezing a bit more performance from your rig in BoS

 

If you use Geforce experience exit out of it before starting BoS (right click the icon in task bar under hidden items triangle)

 

I always right click the desktop (personalise)  and select windows basic before starting BoS , Win aero can use resources even when running in background

 

This app, process lasso

 

https://bitsum.com/processlasso/

 

allows simple one click optimisation, disable possible core parking etc.  right click from task bar and check - bitsum performance  profile, and gaming option, there are many other features, but just choosing these two options seem to help and is much easier than the many registry/BIOS edits etc. needed to do what this small program does

it is very unobtrusive and has given me no issues to date, simply select balanced  profile after playing

 

In Nvidia control panel select - prefer maximum performance under power management

 

In Nvidia control panel - Texture quality- try setting Performance instead of the default 'quality' this can help performance, and I find it hard to notice much, if any deterioration in visual quality,

 

After a clean install of Nvidia  355.60 I am getting/tweaking settings with Nvidia Inspector optimised for best quality with best performance, will post my settings when settled on a compromise I am happy with,

 

Even with great FPS it is hard to find and settle on a good setting with best shimmer reduction, good AA and minimal micro stutter for smoothest picture...more important than simple max FPS or best quality picture IMHO

 

After getting a compromise you are happy with turn off fraps or whatever FPS counter you use and don't worry about framerates  if things are smooth with no visible slowdown be happy and ignore FPS

Great post Dakpilot! I look forward to seeing what you come up with for Nvidia Inspector. Like you, I only run FRAPS while testing settings, once I'm satisfied with performance FRAPS goes away.

[Dakpilot]

Here are my settings, although these are very specific for my monitor, I sit quite close to it and it is 49" 3840 X 2160 native res, although My 970 can run it nicely in 4k with one A/C, if there is much going on my GRX card is overwhelmed (something to be expected), also I cannot run any enhancements.

 

While CPU load is considered for physics and GPU for graphics, when running high res at max on your GPU you are also asking more from the CPU to keep the flow of info fed to your graphics card for processing, if you have a much more powerful GPU than CPU, trying to run the graphics at a high level will stress the CPU especially when it is also at high load for physics calculations, this can lead to micro stutters and glitches even with seemingly good FPS, better to have a stronger CPU as the bottleneck of GPU has less issues, more  issues of AA and graphic enhancements than limitations of min FPS usually limited by CPU.

 

Anyway for the above reasons I usually run BoS at 1920 X1080 however my screen/TV has a processor that upscales to 3840 X2160 native, but it can only do so much and will not improve a bad image or graphic faults, so with that caveat, here are my settings that work for me, 60FPS at takeoff on the ground and all round good image and performance.

 

I imagine they should work also for native 1080P with similar hardware

 

 

 

 

Set Nvidia CP before using Nvidia inspector

 

 

 

I use the terrain .cfg

 

 

One very general tip is that if the Aircraft in the hanger does not rotate smoothly with no judder, then even if ingame FPS is good you are pushing your settings to high, and there will be issues when high load situations occur (big generalisation  ) but valid

 

Hope this may be of help to at least someone, I run these settings with the above posted performance tips

 

**EDIT**  just noticed I had left the - Threaded optimisation to - OFF while experimenting I did not notice any difference from AUTO prob best to leave at AUTO or ON in case there are situations where that may help

Thanks Dakpilot! WIll play around with these, my in game settings are the same except I have HDR on. Also, there is new NVidia whql driver out, 355.82.

[No_85_Gramps]

The control panel changes are working good. The inspector settings introduce some stuttering for me. I am happy with the smoothness, like you said, more important than FPS. I did notice that with SSAO off there was no real change in performance using ultra/high settings, but dropping to normal increased performance slightly. I wonder, and I think it was talked about sometime back, that those settings, ultra/high/normal/low were actually SSAO related. Thanks again for the info. Happy flying!

[No_85_Gramps]

Ooops, meant balanced where I said normal.
