Always running on one thread ?

[gemat]

I am running DCS on a pc with a ryzen 7 5800 x3d. Nomatter how I setup the game, it always runs on one thread that goes to 100% and the game (in VR) stutters. If I disable that core, the load transfers to enother thread that goes near 100% and the game stutters again.
Sometimes the load is somehow balanced between the cores/threads and the game runs great! I am using proccess lasso and PBO2 tuner. It is an improvement but the problem is not solved...
I am watching the stats/fps of OpenXR and I can see that there is GPU and CPU performance to spare like 50% but still when the one thread that takes all the load goes up to 100% DCS stutters...
I am using the Reverb G2, 64 gigs of memory and a 7900XT 20gb of Vram. The games runs with an FPS limit of 55 .... Nomatter how low I set the visual settings when the one thread that the game runs goes to 100% I get stutters....

Actually all I do is disable the E-cores in my bios tweaker (your mileage may vary), but everyone has the single processor maxing out or near maxing out going on.

On my end, I do see that the other cores/threads seem to be utilized and share the remaining load somewhat equally.

Hopefully Vulkan may improve the situation, but right now the single core issue is present to everyone.

However, if you are tweaked right, you really should not be getting a lot of stuttering as a result of this issue.

There are tons of tweaking guides out there, I have no one specific one to give you, but I would suggest that you have not "tweaked" everything you need to tweak to eliminate the stuttering, because as I said, we're all dealing with the single processor running maxed or almost maxed. Let me look a little bit and post some links so you can check those "other" settings and maybe find the "magic bullet" to fix your stuttering.

You might start here. This video has most of the basic settings you should check, and multiple people have responded it fixed their stuttering issues.

DCS 2.9 Optimization Guide in 2D and VR (Quest 2)

I would add a few notes to the video that I disagree with / change:


1. Leave the windows service "Power" on automatic. I think the intent is to disable the "power" options, but if you research, disabling it can bring some bad juju to your pc
2. In Nvidia Control panel settings, in "Vertical Sync", I use "Fast" in all games. It eliminates screen tearing so you can leave "Vsync" OFF in game settings. (SINCE YOU HAVE AN AMD CARD, IF IT HAS A SETTING SIMILAR TO NVIDIA THAT ELIMINATES SCREEN TEARING IN LIEU OF USING IN-GAME VSYNC, USE THAT).
3. I would be leery of his actual "in game" graphics settings. He seems to be turning everything up, WAY up. Use your own judgement on how you need to set those.
When it comes to setting the "in game" settings when it comes to "eye candy", I use MSI afterburner in-game monitor, and fly a sort of unit heavy mission and dial up the "eye-candy" until I get to about 85-90% on the GPU. That leaves you with about 10-15% GPU overhead for any graphics heavy areas you might encounter.

Hi
I have an AMD video card so Nvidia settings do not apply. Still there is absolutely no problem with anything that I add or remove from the settings. My PC can handle the game with quite high settings. The problem is the one core that maxes out at times.
Before the latest update the first core (threads 0 and 1) were maxing out causing the same stuttering effect when I was moving my head. Excluding the threads 0 and 1 made the load mainly move to core 4 (threads 6 and 7) that were high but did not go to 100% so the game ran nicely. At times I could see all cores/threads taking load but most of the work were done by threads 6 and 7.
After that last major update the performance became even better. So much better that I could disable FSR and still get better performance than before that I had FRS at 82% of the native 4320x2160 resolution.
Things went bad after the additional "FIX"! After the fix there was ALWAYS a thread reaching 100% causing stutters and I cannot find a way to keep it under 100%. I even tryed to overclock the 4th Core but it did not make much difference....
The game is generally playable, but if I could eradicate this little hickup it would be awesome!

You should post over in the official forums.

As I noted, everyone deals with a 1 or 2 cores going to 100% at times. That doesn't mean you're going to get a stutter every time it does that.

That is why I suggested that you look at others suggestions / settings, and make sure all the other things (including windows settings) are tuned correctly as some of those things can cause stutters.

I would also thing fooling around and moving your cores in use might be doing more harm than good.

Post over in the official forums in the performance areas. Maybe others can explain it better than I do, but again, you aren't dealing with something that others don't deal with as far as cores hitting 100%. That shouldn't be causing the massive amounts of stuttering you are describing. But I suspect there are other settings at play that you need to check or set, such as HAGS, virus software exclusions, etc. You don't make any mention of checking those types of settings, you seem entirely focused on eliminating the cores hitting 100%, which I don't think is going to happen.
