RvL

I have used steam years ago but not with DCS. I normally only see more negatives using steam vs standalone. So your saying you dont need the oculus software when using steamvr? Cant imagine that being true. Im gonna check whatever that dx11 option does for dcs and if that helps my vr performance. Thanks for the info!

Same issue here. Similar specs as you, also Rift S and RTX3070. I have found some similarities with players having bad fps in vr using oculus and also 3070's. I have tried almost everything to fix this. No solution yet unfortunatelly. Im almost starting to think this is a Oculus only thing. Im also getting overall bad fps in mp. Lots of kickbacks to 20 or less fps. Changing ingame visual settings dont make a change in fps. Next thing im gonna try is Rebar. But im running out of ideas.

Just tried 2D, but there is no way back. I turned down my pixel density a bit to 1.2 and mssa to 2x wich ofcourse increases performance. From the current tests i did it does look promising. Hopefully i can get used to the decreased visuals. Seems like its either that or major stuttering, ghosting and screentearing. A VR focussed patch would be neat.

No im not using the mod anymore since 2.7 came out. Was just wondering if it still has any benefit fps wise.

Just had a lot of screentearing and low fps again. Not sure what to do anymore. Does the vr shadermod still has any use since 2.7?

Since yesterday after i updated the last 2 updates for DCS World, and i cleaned up my SSD's from old drivers and other old files im having better stable mp fps and somehow my graphics look better. Yesterday i did had 1 moment during MP i got major stutters and lag with screentearing for 10 seconds. But overall im happy with my current performance and visuals. Edit: nevermind. Just had terrible fps again with screentearing damnit...

Box was unchecked for some reason, but on or off didnt make any difference, untill the latest 2 patches came out and that was solved for me. Today i cleaned up my ssd's using windows "cleanup disk" utility, and i got rid of 7 gigs of old drivers and stuff. Since this and the latest 2 patches im getting better fps, but also my graphics look better. Not sure how or why, but im quite happy with my current performance and visuals. I still get some low fps down to 20 sometimes, but its way less noticiable. Im also very happy with the cloud jitter fix wich fixed it 100% for me. Clouds are also looking way better since the patches. I noticed that when i overclock my cpu from 3.4 to 4.1ghz, i get crashes. Without OC i havent experienced any crash so far.

Yep ED fixed it! No more jittering! Great job ED.

Here an Rift S user aswell, with weird problems like screentearing, low fps, massive stuttering at certain not explainable times on MP servers. Tried everything without being able to fix it. Change of visual settings do not change anything to my fps. My oculus sometimes even get so much stuttering with screentearing it loses connection with the gane and gets me back into the oculus home screen with DCS still running in the backgound but unable to get it back into oculus without closing DCS and restarting. Never had anything like this as it seems before the 2.7 patch for some reason.

Im having the same issues and am running a 3070 with a Rift S with groundtextures to low. Im not sure this can be related with running low on Vram. Even turning every setting to the lowest doesnt make any difference, same low fps dips etc.

I believe i have that box checked. I've heard that this is also a bug in 2.7 forcing VR players to alt enter for full screen. I'll check it out tomorrow when im home. Thanks.

Havent experienced CTD's or the extreme screentearing with massive lag/stutters. But i still have big drops to 20fps on PVE servers with arround 20 or more players. Changing my visual settings from low or very high doesnt fix it or make any change in fps. I guess my RTX3070 doesnt seem to be the issue. I was thinking it might be my cpu, ryzen 5 2600. But member Flappie says its more then OK for DCS. Im not at home to be able to make a screenshot of my settings. but normally i have my settings like: Medium to high with 4xmssa. Shadows flat. 1.0PD with OTT AT 1.2. When entering the cockpit i always turn off mirrors to save fps. Tomorrow im going to try to restore Nvidia settings. See if that helps. @NathB what module(s) do you fly? Maybe its module depended. Im mostly flying the F14, wich already eats more fps then any other module.

Hi Flappie, thats something i have to do already everytime i play, otherwise my cursor goes outside of the DCS screen making my window go out of focus.

Havent experienced a CTD anymore. I do still get big drops to 20fps or even lower on pve servers. Looks like when a server has +/- 10 players im okay with stable 40fps. With players up to 20 or more i get drops to 20fps with some screentearing at the edges of my VR view when moving. I have tried setting my visual options at max low or off, but joining the same servers the frame drops continue. So visualy it doesnt really matter what settings i put it. Does this had something to do with my cpu? I have a ryzen 5 2600. Time for a upgrade?

We sure arent alone in this. I believe 2.7 brought this with it. In the earlier versions of DCS World i have never experienced the problems we are encountering right now with 2.7. Lets hope its fixable and unfortunately part of the open beta. I did not uninstall DCS, only the module and mods and did multiple slow repairs. Those didnt help. I also did not try previous NVidia versions. Perhaps we can give that a shot, who knows. I only play DCS, i do not fly any other VR games in my simpit. So no idea if this is a DCS only issue. Yesterday though, after a playbreak for some days i installed the latest verion of DCS, and had a online PVE playtime for about 2 hours with no issues. I did had some fps losses down to 20fps but i guess that was due to many things happening at once. The weird visual lag or DCS crashing out of oculus did not happen. Maybe it was a luckyshot, later today i will do some more online testing. Lets see what happens. I'll keep you posted.

Tested a bit of flying on PVE servers with a new 750W PSU. I havent had any CTD yet, hopefully thats in the past. I do notice a sudden fps loss from a solid 40 to 20fps, with nothing big or anything fps demanding happening during flight. If the drop happens it also makes my screems extremely laggy and nothing seems to be able to fix it wich forces me to exit the game. Even the Oculus menu has become very laggy what makes me start to believe its not even a DCS problem, but an Oculus problem.

Hi NathB, Been reading through your posts. I have made an post myself about problems flying VR in MP, mostly about CTD problems, but im also experiencing sudden framedrops to 20fps out of nowhere. Im using the Oculus Rift S. Just like you said, nothing really happens what explains the sudden drop to 20fps. When it happens, im also getting some kind of screentearing and massive stutter/lag making it unplayable forcing me to exit the game. Like you said in your last post thinking about buying a new PSU, i have just done that last week. Having a RTX3070 myself, and used to have a corsair 550w gold, i upgraded to a Sharkoon 750W gold. Unfortunally it did not solve the problem.

Thanks for replying Flappie. Unfortunally i already reinstalled the module. I also got a BSOD a little later. Im not sure whats going on. For now im considering a upgrade of my powersupply cause i have a corsair 550W. The internet says it should be enough while having a RTX 3070 wich has the requirements of a minimal of 650W, but ive got the feeling my pc is struggeling sometimes to deliver.

Just had another CTD, but no log file has been made. I just dropped a mk82 from the F14 and while looking back at the impact it quits VR. VR just quits with audio of the game still going on. Sounds like the game is still running and is responsive to keybindings like changing views from the sound of it. Desktop visual is freezed. Had to cntr alt delete to stop dcs. This is getting really annoying.

Here's mine. [Window][Debug##Default] Pos=60,60 Size=400,400 Collapsed=0 imgui.ini

Thank you for helping Flappie!

Yeah im not sure if its the overclock thats causing it. I forgot to mention i also changed my pagefile to 32gb after my last crash. Today i have flown for another 2 hours this afternoon with no crashes! I do hope someone like Flappie will respond on the log to help us understand why it crashed.

I have just managed to play for 3 hours on a server without crashes, this time without overclocking my CPU. I wonder if thats the problem. @5ephir0th Do you overclock your CPU?

With the help of member Flappie i have found where to look into the logfile, but i do not understand the meaning of these files. 2021-05-13 13:08:44.045 INFO EDCORE: D:\DCS World OpenBeta\bin\ImGui.dll 2021-05-13 13:08:44.048 INFO EDCORE: # C0000005 ACCESS_VIOLATION at 033E1E5A 00:00000000 2021-05-13 13:08:44.052 INFO EDCORE: SymInit: Symbol-SearchPath: '.', symOptions: 532, UserName: 'Richa' 2021-05-13 13:08:44.055 INFO EDCORE: OS-Version: 10.0.19042 () 0x300-0x1 2021-05-13 13:08:44.101 INFO EDCORE: 0x0000000000051E5A (ImGui): ImGui_ImplDX11_InvalidateDeviceObjects + 0x6A 2021-05-13 13:08:44.105 INFO EDCORE: 0x0000000000052BD9 (ImGui): ImGui_ImplDX11_Shutdown + 0x9 2021-05-13 13:08:44.109 INFO EDCORE: 0x0000000000051667 (ImGui): ImGui::ed::shutdown + 0xB7 2021-05-13 13:08:44.112 INFO EDCORE: 0x0000000001C38FD3 (DCS): AmdPowerXpressRequestHighPerformance + 0xE49FCF 2021-05-13 13:08:44.113 INFO EDCORE: 0x0000000000A071BE (DCS): SW + 0x71680E 2021-05-13 13:08:44.116 INFO EDCORE: 0x0000000000017034 (KERNEL32): BaseThreadInitThunk + 0x14 2021-05-13 13:08:44.116 INFO EDCORE: 0x0000000000052651 (ntdll): RtlUserThreadStart + 0x21

Great info Flappie, thanks!
