AdrianL Posted October 20, 2023 Share Posted October 20, 2023 (edited) See this post. For me it was CPU 8 but see if you have a maxed out CPU. If so, try to remove affinity from that CPU Edited October 20, 2023 by AdrianL Link to comment Share on other sites More sharing options...

I cannot reproduce this issue (since I have a Ryzen CPU) and I keep bumping the internal report nonetheless. As I said earlier, one fellow tester is affected, though. How can ED be barely able to reproduce this when you have a whole thread full of people who can reproduce it on a daily basis? I can reproduce it right now if you want. Is three anything we can do? Do you need more logs, do you need more system info, should we run some debug build? It's getting a bit silly, MT was super promising, now other features are depending on it, but game-breaking, perfectly reproducible stutters are ignored for months? What are these priorities?

Ballinger French Posted October 20, 2023 Share Posted October 20, 2023 (edited) Has anyone affected by this issue tried updating their motherboard chipset drivers and/or verifying they have all the latest Windows updates? Although I haven't installed 2.9 as of yet, I have been running the 2.8 MT version for about six months using a I7 12700K CPU (hyperthreading enabled) and Windows 11 Pro without issue. SSAA never worked with the 2.8 MT version, so I was never able to use it, FYI. Edited October 20, 2023 by Ballinger French Link to comment Share on other sites More sharing options...

Ballinger French Posted October 20, 2023 Share Posted October 20, 2023 (edited) Weird. In the past, running Prepar3D Flight Simulator, I had problems with certain add-on aircraft causing stuttering which I traced down to an overloaded CPU as others here are mentioning having issues with DCS 2.9 Using windows Task Manager, I masked half the cores on my CPU with Prepar3D still running, then immediately reactivated them again. This had a net effect of 'rebalancing' all the threads running on different cores so that no single core was maxed. In other words I didn't have to keep any core masked but instead I could essentially rebalance the distributed load as I described.

speed-of-heat Posted October 20, 2023 Share Posted October 20, 2023 Hi All, I have a 12700k and when DCS is being used i see a huge spike in activity on CPU's 16, 17, 18, 19, which are the eCores, I have checked with a friend and he is seeing the same thing? so Why would DCS choose to use the eCore rather than the pCores?

AKULA_OPTIMUS Posted October 20, 2023 Share Posted October 20, 2023 I can confirm stuttering go (mostly) away when using the ST version instead of MT. I have an i5-7600 CPU @ 3.50GHz, Its 4 cores, not 8, how to do the CPU affinity stuff with 4 cores? Thank you Link to comment Share on other sites More sharing options...

I put this in the target box of the icon shortcut C:\Windows\System32\cmd.exe /C START "" /AFFINITY 0xFFFFFFFFFFFFFEFF "E:\Eagle Dynamics\DCS World OpenBeta\bin-mt\DCS.exe" Change the path, obviously. You can add any DCS params at the end. The affinity mask will be based on your actual CPU but for the i9-13900 it is the one listed above (See https://bitsum.com/tools/cpu-affinity-calculator/). Also, if you read thru this whole thread, for some it is CPU0, etc. Whatever CPU is maxed when you just start DCS. So the affinity mask needs to change accordingly. If you look at the top of your DCS log you will see it switched off if done correctly, This worked to fix the stuttering issues for me, at least Edited October 20, 2023 by AdrianL 2 Link to comment Share on other sites More sharing options...
Gh0st007 Posted October 20, 2023 Share Posted October 20, 2023 (edited) I can confirm since the recent patch (2.9) it has made the stuttering worse. In some cases I can't even fly. Core 8 and core 10 is fully "pinged" aka full usage so to speak. I posted a month or so ago and it's getting worse. I have current bios version and drivers up to date, problem still happens. You can see - CPU BOUND (Main Thread) in red when the stuttering happens.

KoleTang Posted October 20, 2023 Share Posted October 20, 2023 For those having the "Major Freezes" issue. Which can seem like a stutter if the freezes are short. If you get a long freeze try clicking your mouse anywhere. My experience has been that this will immediately end the freeze. From my professional experience, this would lead me to think that DCS is losing focus and the mouse click brings it back. This could be perhaps from a hidden window. What is particularly frustrating is that it seems to be totally random in occurrence. You can fly the same mission again with no issue. Perhaps it is some debugging code showing up in production. I would be interested in knowing if others can get the same effect from clicking the mouse. To be clear this will only work on the long freezes, not the consistent stuttering. I have been waiting to post this until 2.9 was released hoping it may be fixed. Unfortunately not. This needs to be elevated in priority as the single-thread bin updater now launches the multi-threaded preview. At least that is what it says at the bottom of the main menu. 1 Link to comment Share on other sites More sharing options...
Mr_Blastman Posted October 20, 2023 Share Posted October 20, 2023 Before the 2.9 update I could fly the Apache in the Instant Action Live Fire Range mission with butter smooth framerate. Everything was perfect. There were no stutters, there was no hitching. After the 2.9 update... Nighmares! Hitching. Stuttering. Popping. The moment I take off I begin seeing intermittent stutters and frame skips. This is driving me nuts! What is going on? System: Intel 7700k CPU 32 gigs RAM NVIDIA 1080 GTX GPU DCS loaded on SSD Operating system on NVME .M2 SSD Page file on a separate SSD Nvidia driver version 536.67 Steps taken to try to resolve: Deleted DCS shader caches Deleted NVIDIA shader caches Rebooted many times Nothing fixes. I had a similar issue almost a year ago, but that was eventually resolved. Alas, here I am again, and I'm going insane. I need butter smooth framerates to fly precisely. As things are right now, DCS is a paperweight again. Please help. Thank you. Link to comment Share on other sites More sharing options...

Honestly, it's probably not even a specific issue, but just simply bad performance as your CPU is pretty outdated by now. 33 minutes ago, KoleTang said: For those having the "Major Freezes" issue.
