AMD Ryzen 7 5800x/ Nvidia GeForce RTX 3080Ti settings.

[Chilli_40]

I'm sorry to be a pain, but I've been trying to figure out what the best settings are for this rig. All the research I seem to find is usually outdated, with half the settings not even listed anymore in the options! What I'm stiving for as I'm sure everyone is, best visual quality yet keeping maximum fluid frame rates. Here's my pc's specs I'm working with:

-Ryzen 7 5800x

-NVidia GeForce RTX 3080Ti

-TUF Gaming X570-Plus

-32GB DDR4 3200

-Oculus Quest 2

I'm trying to figure out best in game settings, Nvidia settings and Steam settings. I installed a while back the FSR app, does it work with IL-2 if so, how do you know it working? I have only been able maintain around a 45fps rate with most settings on moderate, clouds medium. Thanks in advance for sharing what works for you!

My startup.cfg file and my Nvidia Inspector settings. My rig is similar to yours (3080 instead 3080ti, same CPU, 64GB RAM 3600GHZ).

I don't use VR. Screen 4K (3840*2160).

There is a machine with similar config to you (you've got a more than adequate setup) in the benchmark spreadsheet in the following thread:

SYN_Vander BENCHMARK v6 to measure IL-2 performance in monitor & VR

 

There is also really good advice on starting setup for a Reverb G2 (arguably good advice for any VR headset) in this thread:

Best settings for a 3090 for a Reverb G2 and 9900k

 

I would arguably start with dburne's setup and depending on your framerates, start bumping things up one at a time (maybe clouds last) to suit your own tastes.  I prefer blurry landscape myself while dburne like sharp.  I also run FSR mod but make sure if you do that you turn off sharpening in the iL-2 settings.  I ran the SYN_Vander benchmarks and got no substantive difference with FSR on or off (but running it seems to make me feel better).  Also make sure to turn off bloom (bloom=0) in the startup.cfg (under some conditions it will keep setting it to 1 every time you make a change to graphics settings so I make a habit of constantly checking or make read-only (but I think this could screw with updates).  With the machine you have you should be able to run 90fps with a pretty picture.  I have G2 so maybe your 45fps is a Quest thing.  There are lots of threads about optimizing Quest 2 hereabouts and others about spotting versus beauty.  

 

I have a 5950x and a 3090 and run rock solid 90fps under dburne's settings and you are not far behind my rig given I have high latency RAM (working on that problem).

 

My startup.cfg

The or_render_eye = -1 is a new setting that will finally fix the left/right images on your monitor and allow you to choose one image (1=left, o=both, -1=right).. Huzzah!

 

Good luck

Paul

I would first be sure that your system delivers as expected in just 1080p monitor (no VR). To do that you simply need to run the SYN_VANDER benchmark in 1080p. Then, if your fps are similar to other test with the 5800X then you can go to test the GPU with the 4K test.

If both tests are ok then it is just a question of adjusting your settings.

Most of the in-game settings affects just the CPU load (except clouds and MSAA which loads GPU).

I wold try to avoid mirrors since they load the CPU heavily.

 

I have no experience with the Quest2 in IL-2 (not very fun of Meta) by I think that the performance of the Quest2 (for the same resolutions) is worse that other devices (Index, G2, G1) because the data needs to be heavily compressed-decompressed to be sent through the USB cable and this add extra load to CPU (or GPU?).

 

You can use fpsVR tool to know exactly who is lagging your fps while you play.

Thank you for all the help!
