Mr_Blastman Posted January 1, 2023 Share Posted January 1, 2023 (edited) Ever since the latest open beta/live update my sim has unplayable hitching and stuttering. I used to have butter smooth framerates before. Nothing has changed on my system. My drivers have not changed. Literally nothing else has changed except DCS World's version update. That's all. Other games run fine. DCS is porked. Unplayable now. The sim is a paperweight. Help. Please.

cthulhu68 Posted January 1, 2023 Share Posted January 1, 2023 There are reported issues with shadows. For me turning them off and lowering a few settings almost got me back to pre 2.8 performance. Link to comment Share on other sites More sharing options...
Mr_Blastman Posted January 1, 2023 Author Share Posted January 1, 2023 Seems after further testing the problem is mainly occurring on the Caucuses firing range mission in Instant Action for the Hind. Running smooth on Marianas firing range for 'Shark 3, as well as smooth on Syria firing ranges for both Hind and 'Shark 3. Link to comment Share on other sites More sharing options...

Jakes Posted January 3, 2023 Share Posted January 3, 2023 Hi @Flappie I am having the exact same issues. Constant stutters of up to 3 or 4 seconds, sometimes more, for no reason, on missions that worked flawlessly for 100's of hours before this latest patch. I just spent 2 days trying everything I could find in the forums and even a full pc format...No change whatsoever. So I hope these attached items help...

Flappie Posted January 3, 2023 Share Posted January 3, 2023 Hi @Jakes. I see you are DCS-BIOS and pw-dev_script at the same time. Please try renaming your Export.lua file to "Export.lua.bak" so these scripts are not loaded by DCS. Do the stutters go away? Don't accept indie game testing requests from friends in Discord. Ever.

Flappie Posted January 3, 2023 Share Posted January 3, 2023 (edited) OK, at least this is now out of the equation. Does your motherboard come with an internal GPU? If it does, please try this in your Windows control panel: To set the default GPU for your application or game, you'll need to associate your games with it so your computer will know which GPU to use. From Start Icon, type "Graphics Settings". Click the results from System Settings. Click Desktop App. Click your application. If your application is not on the list, you will need to browse to the folder where the .exe file is located. Once identified, click Options. Set the application to your preferred GPU. Click save. Then try this: Edited January 3, 2023 by Flappie Don't accept indie game testing requests from friends in Discord. Ever. Link to comment Share on other sites More sharing options...
Jakes Posted January 3, 2023 Share Posted January 3, 2023 @FlappieNo onboard graphics, only the 3090. I had already tried the fix by linebacker before I posted here with no effect. I have lowered the quality of all my settings, tried to disable hot plug, tried it with and without head-tracking (both FacetrackNoIR and AItrack/opentrack), tweaked my nvcp settings... Like I said...everything was flawless on max settings before this update...now it wont even run when I dial it back... Any landing that doesn't require the jaws of life....is a good landing...

Jakes Posted January 4, 2023 Share Posted January 4, 2023 Well @Flappie and @jurinko I just got it sorted out... First thing I did was tweak my NVCP settings. Used this video by @JUICE-AWG from the Air Warfare Group and that helped a lot to tweak my settings(never had the 30fps issue)...but it turns out I needed a BIOS update, not sure why it only gave grief now but such is the voodoo of pc's, and to activate "Resizable Bar" in the BIOS... PC is hitting Mach 2 and still accelerating... 2 1 Any landing that doesn't require the jaws of life....is a good landing... Link to comment Share on other sites More sharing options...

PC is hitting Mach 2 and still accelerating... Funny thing about ReBAR. I recently discovered it may not work in DCS since Nvidia have set up an allowed-list model whereby specific games will be configured for ReBAR with an Nvidia GPU. To actually enable it for DCS you need to get Nvidia Profile Inspector. See the following thread I don't know if enabling ReBAR in the BIOS creates a placebo effect for the user who expects it to have some benefit, or if ReBAR actually works in DCS at the point of enabling it in the BIOS.

Thank you for looking into this. I have attached the files. Mine did not generate a new export.lua?

Flappie Posted January 7, 2023 Share Posted January 7, 2023 (edited) You should find an Export.lua file in your "Saved Games/DCS/Scritps" folder, since you have SRS installed. Please check again. In the meantime: I looked at your dcs.log and I don't see anything wrong. Your dxdiag log shows you have 6 HDDs in your PC. Is DCS installed on one of them? Can you please run the following command in a CMD window and paste the result here? wmic pagefileset list /format:list Edited January 7, 2023 by Flappie Don't accept indie game testing requests from friends in Discord.

Flappie Posted January 8, 2023 Share Posted January 8, 2023 (edited) That is strange. WMIC says your pagefile is empty (init size = 0, max size = 0). Would you mind attaching a screeshot of your pagefile settings? https://mcci.com/support/guides/how-to-change-the-windows-pagefile-size/ By the way, the I:\ drive is almost full. You should move your pagefile to drive C:\ or J:\. Since you have 32GB of RAM, ensure the pagefile has init size = 32768 and max size = 32768 (DCS sometimes needs about 50 GB of memory to run, especially over Syria).

Mr_Blastman Posted January 8, 2023 Author Share Posted January 8, 2023 I like to keep my pagefile on a different physical drive from DCS, helps performance, but also keep on a different drive from windows as well, to maximize throughput on demand. My pagefile is set to "system managed" within the advanced system settings -> performance options -> virtual memory, so while it currently is 32 gb in size, it can fluctuate as needed--and does grow to over 50 gb sometimes when DCS is active.

Flappie Posted January 8, 2023 Share Posted January 8, 2023 OK, but you need to give your drives more free space anyway. Don't accept indie game testing requests from friends in Discord. Ever. Link to comment Share on other sites More sharing options...
Mr_Blastman Posted January 8, 2023 Author Share Posted January 8, 2023 (edited) Swap/Space aside, I never had any stuttering and hitching before this update. Nothing has changed on my system. No driver updates, no software patches except for DCS. I just noticed the hitching and it was rather severe on a multiplayer server today. This was not a problem before.

I'm in the same boat, Did a complete reformat of my drive, reinstalled everything. Still same issue. Performance far reduced from before the update. Frame times are rather spikey. Only solution I've found to allow me to play, is to turn down resolution multiplier in VR / reduce graphics settings :((( Edited January 14, 2023 by Sl1ck Link to comment Share on other sites More sharing options...
