So is it stuttering in the game or stuttering in the menu as well?

sze5003 Posted November 13, 2023 Share Posted November 13, 2023 So is it stuttering in the game or stuttering in the menu as well?Mostly it's pretty consistent stuttering in game while I'm flying. Once in a while it will freeze in the main menu or on exiting a mission and that is when unchecking cpu 8 from affinity list unfreezes it. But the stutters while flying occur randomly and often in VR. Even when I see that asw is engaged and I'm at 45fps I'll get stutter or I'll see the frame time graph jump both cpu and GPU graphs dip. I'll usually get the stutter before I realize the graphs have dipped too. 1 Asus ROG Strix Z790-E | Core i9 13900K-NZXT Kraken X73 AIO | 32GB DDR5 G Skill Neo 6600mhz | 2TB Sk Hynix P41 Platinum nvme |1TB Evo 970 Plus nvme | OCZ Trion 150 960GB | 256GB Samsung 830 | 1TB Samsung 850 EVO | Gigabyte OC 4090 | Phanteks P600S | 1000W MSI MPG A1000G | LG C2 42 Evo 3840x2160 @ 120hz Link to comment Share on other sites More sharing options...

Have a look at your dcs.log and look for errors. I have a similar system to yours, and even in VR I can fly stutter free with my settings maxed out.

Kobymaru Posted November 16, 2023 Share Posted November 16, 2023 Interesting video from Jabbers about VRAM usage: His workaround was to reduce the number of CPU cores so that I/O threads don't step on each others toes when loading textures. Potentially related to our issue, is our "disable core 8" solution maybe similar to his "use only 4 cores"? Or is it just coincidence and another reminder that Multithreading is hard on modern CPU architectures? 1 1 Link to comment Share on other sites More sharing options...
speed-of-heat Posted November 16, 2023 Share Posted November 16, 2023 I suspect a bit of both, for me dropping to four cores really tanks my performance, dropping core 0 and then dropping all the v-cores and e-cores gives me the best results I also suspect that jabbers is talking about a similar, though different problem 1 SYSTEM SPECS: Hardware Intel Corei7-12700KF @ 5.1/5.3p & 3.8e GHz, 64Gb RAM, 4090 FE, Dell S2716DG, Virpil T50CM3 Throttle, WinWIng Orion 2 & F-16EX + MFG Crosswinds V2, Varjo Aero SOFTWARE: Microsoft Windows 11, VoiceAttack & VAICOM PRO YOUTUBE CHANNEL: @speed-of-heat Link to comment Share on other sites More sharing options...

I can tell you the MT version absolutely hates my 4 core i5-7500 but the ST version works perfectly smoothly in it. If they take the ST version away I'm going to be forced to spend all my module money for the foreseeable future on a new CPU and maybe a new motherboard to support it.

If you're running the OpenXR Tool kit Companion App, try disabling or runnig it in safe mode. Mine recently started doing the 5 sec freeze. I was testing something else and switched off turbo mode, problems for me started after I switched it back on. After realizing the stutters went away in disabled mode, I uninstalled then reinstalled OXRTK and it's fine again.

redshark Posted November 20, 2023 Share Posted November 20, 2023 My PC config is AMD 760K GTX1660S 32G RAM WD hardisk , When I updated to 2.9, use MT mode to run game ,very stuttering in the game ,I use the processor lasso to disable one cpu core, try everyone , still stuttering and freeze, but yesterday , When I disable CPU1, still stuttering , then I to enable CPU1, I found the stutter disappeared .............. 1 Link to comment Share on other sites More sharing options...
durp Posted November 20, 2023 Share Posted November 20, 2023 I can only add that the last update increased the frametimes for me in the menu from 1.6ms to 10.5ms (CPU) and DCS can't maintain 45fps in VR that way (in the menu!), despite both frametimes being in the green. The menu is not 'stuttering' or lagging, but that drop in performance in MT is massive and flying in MT is no longer an option.... In comparison the ST version has a CPU frametime of 0.8ms in the menu and and the HMD is locked at 90fps (HMD max) Link to comment Share on other sites More sharing options...

Yodeling Posted January 14 Share Posted January 14 (edited) I'm just curious whether this is even being worked on? The issue is fairly old and it sounds like it's affecting a lot of people. I would totally understand if MT was problematic for a small number of people with very non-standard rigs, but it mainly seems to affect people with the latest Intel CPUs and latest Nvidia GPUs. I assume ST will be retired at some point, and when that happens, are some of us going to find ourselves without a playable game?

Hillman Posted January 14 Share Posted January 14 I moved the audiodg.exe process to a seperate thread from DCS and set the fps limit to 60 with Nvidia CPL. Also put DCS on P-cores only. This seems to have helped some, but still I get some audio and game stutters, so hoping ED can fix this soon. I play almost only in VR, the few times I tried flatscreen I don't have any issues and get extreem FPS's... In ST VR it seems to work, but then I get issues with FPS on complex campaigns, so MT is almost a must.

So do I, but as long as that's not the case I keep disabling CPU core #8 for DCS in the Task Manager everytime I launch DCS which makes the issue go away, so I'm not afraid of DCS becoming unplayable if ST gets removed eventually. Having to use such workarounds is pretty annoying of course, but at least it allows me to enjoy DCS while ED tries to fix the issue which doesn't seem to be trivial.

Frankly, I don't understand how this is possible. I won't presume to understand the complexities of debugging a complex game engine, but as someone who fixed thousands of bugs over several decades (even multithreading bugs), it never took me more than a few days to pinpoint an issue, and no more than a week or two to fix it (usually a couple hours). The only time I couldn't fix a bug quickly is if: A) I couldn't reproduce it, or B) It wasn't priority. I find it hard to believe that after many months this issue cannot be reproduced, especially since this seems to be pretty consistent with every 12th/13th/14th gen Intel CPU in stock configuration, and it can be reproduced by literally launching the game and sitting in the main menu. Which leads me to believe that the problem is option B (It's not a priority). Edited January 17 by Yodeling 2 Link to comment Share on other sites More sharing options...
