C3PO Posted October 31, 2022 Share Posted October 31, 2022 (edited) Hi - noticing a significant FPS drop in 2.8 in VR (it is otherwise a lovely update). After going into the cockpit scene, the textures take up to 10 seconds to load and looking around is choppy. Rig is 5800X + 3090FW Ultra + 4200M.2 drive and 32GB RAM. There were no issues like this earlier this year. Gone back to nVidia drivers from late July / early August, no joy. I am running Win11 which I am not too pleased about generally, and cannot now "downgrade" to 10. Is there anything in the OS settings that I can tweak? Checked SteamVR settings for my HP G2 and they seem the same as before. Oh, I deleted the contents of FX and metashader folders. Thanks for any help / advice.

ED Team BIGNEWY Posted October 31, 2022 ED Team Share Posted October 31, 2022 Hi C3PO we are looking into it. We have a shadows issue that maybe contributing to it. In windows 11 open your command prompt as admin and type logman stop HolographicShell -ets and press return, it will turn off windows 11 vr logging and save some frames. We will continue to look at the data in 2.8 and tweak as necessary, thank you 1 4 Forum rules - DCS Crashing?

Antix70 Posted November 1, 2022 Share Posted November 1, 2022 Same problem for me, huge FPS loss with the update, from 45-50's down to 25-35. All of the performance I got out of upgrading to OpenVR/OpenComposite has vanished. Wasn't there talk of ED maybe supporting OpenVR or OpenXR, or something other than SteamVR? I was able to execute that command line by running cmd.exe in Admin mode. So I will see how it performs next time I'm in the game. Link to comment Share on other sites More sharing options...

You used OpenComposite to utilise OpenXR Link to comment Share on other sites More sharing options...
hanab Posted November 1, 2022 Share Posted November 1, 2022 Same problem too. Big fps drop between 2.7 and 2.8 and long texture load. I am on windows 10 and rift s. All is up to date. 2 Link to comment Share on other sites More sharing options...
Elphaba Posted November 4, 2022 Share Posted November 4, 2022 1080ti, 8700K o/c to stable 5.0ghz, 64gb ram, ssd. I went from 40-45 fps with shadows on, Ssao, sslr etc all on and global cockpit illumination on 2.7 to 18-24 fps with shadows off (except terrain object to flat) ssao/lr etc all off and lower clouds/textures and no global cockpit illumination. This is unacceptable. Z-depth on shadows isn’t the only problem. Link to comment Share on other sites More sharing options...
C3PO Posted November 4, 2022 Author Share Posted November 4, 2022 The patch hotfix, understanding it wasn't a "be-all" repair job, has resulted in the same FPS issues for me. It takes 6 seconds to load cockpit textures, and 10 seconds to load ground textures (replacing the sea) in any particular mission. Earlier this year they'd both pretty much load up instantly.

edmuss Posted November 4, 2022 Share Posted November 4, 2022 I've noticed that if you load a mission where you don't need to choose a slot then it doesn't take any time to load at all. As soon as you need to choose a slot it results in a long texture load, about 3-5 seconds for me typically. 1 1 Ryzen7 7800X3D / RTX3080ti / 64GB DDR5 4800 / Varjo Aero / Leap Motion / Kinect Headtracking TM 28" Warthog Deltasim Hotas / DIY Pendular Rudders / DIY Cyclic Maglock Trimmer / DIY Abris / TM TX 599 evo wheel / TM T3PA pro / DIY 7+1+Sequential Shifter / DIY Handbrake / Cobra Clubman Seat Shoehorned into a 43" x 43" cupboard.

Cayman41 Posted November 7, 2022 Share Posted November 7, 2022 With a fresh install of Windows 11 (and all the Windows tricks from Thud enabled) and a fresh install of 2.8, im having to significantly turn down settings to get a suitable experience in MP. I’ve turned off all shadows and reverted to the VR settings tab and still have issues. During 2.7 I had a lot of settings turned up quite high and it ran quite nicely in MP. It runs okay in single player Instant Action as long as I turn shadows off, but horribly in MP. My computer: i9-12900K, 32 GB RAM, 3080Ti, Valve Index.

dutchili Posted November 7, 2022 Share Posted November 7, 2022 Let's hope for an update. In contrast to many others is in had increased performance when 2.8 was released so I guess something changed that really helped (my oculus). It was gone with the patch and I had turn things back down too. Just imagine what happens with multi core. We might see close to similar performance as 2d. I like that thought!!

jonfog Posted November 7, 2022 Share Posted November 7, 2022 I just noticed that F18->Training->Taxi and Takeoff gives me around 37 FPS whereas F18->Instant Action->Caucasus->Cold and Dark gives me 50+ in FPS Could it be the Clouds? Otherwise it may be the scripting of the training. Same aircraft and map Link to comment Share on other sites More sharing options...

I'm just about there, myself. It's really bad right now. In a busy MP server I wouldn't have a high framerate but it would be relatively smooth and definitely doable, targets could be tracked while rolling around and such. Now it is a choppy slideshow that is impossible to function in, and it was the Caucuses map (one of the better performing maps). I am REALLY looking forward to the long-awaited engine upgrades! Good luck fixing the issues and getting framerates/frametimes back where they should be, devs, and even more luck updating the engine!

dureiken Posted November 25, 2022 Share Posted November 25, 2022 (edited) Hi @BIGNEWY made some more tests, and here are the results, helped by @edmuss , for a 12600k, 4090, 64GB and reverb G2, on openXR with fresh new Win 11 install and last nvidia drivers. Settings on HIGH, just playing with terrain shadows. Made all tests twice to be sure. And perf track is disabled of course. As we can see, we have a lost of performance between 2.7 and 2.8, even without shadows, around 0.5ms of GPU, nothing on CPU. The real problem is with shadows, on 2.7 we can see that flat shadows costs just a little (0.4ms) where it costs a lot more in 2.8 (1.5ms !!). And the total lost for default shadows from 2.7 to 2.8 is more than 20% for me. Hope it can help and you will be able to find something in your team, if I could contribute don't hesitate ! Thanks a lot Edited November 25, 2022 by dureiken 2 Link to comment Share on other sites More sharing options...

edmuss Posted November 26, 2022 Share Posted November 26, 2022 I've just finished running some back to back testing specifically on the three terrain shadows settings for corroboration. Rolled back to 2.7.18.30765 and recorded a short track flying over Beirut in the A10. Replayed the track with each terrain shadow setting and all others as per my normal config. Updated to 2.8.0.33006 and repeated the three tests. There is some performance lost between OB's which is to be expected with the new lighting. The main issue is with the flat shadows now incurring a much larger performance penalty than they did, 1ms of lost frametime, presumably due to the soft edges? @BIGNEWY are the soft edges intentional on the current flat shadows or are they meant to be hard as per 2.7? My personal preference would be to retain the option to use the same hard edged shadows as 2.7 or perhaps be able to seperate the default/flat/hard/soft into different options? 2 Ryzen7 7800X3D / RTX3080ti / 64GB DDR5 4800 / Varjo Aero / Leap Motion / Kinect Headtracking TM 28" Warthog Deltasim Hotas / DIY Pendular Rudders / DIY Cyclic Maglock Trimmer / DIY Abris / TM TX 599 evo wheel / TM T3PA pro / DIY 7+1+Sequential Shifter / DIY Handbrake / Cobra Clubman Seat Shoehorned into a 43" x 43" cupboard.
