FPS limit set bellow 150 causes stutters (Core parking force disabled in registries)

[AJaromir]

As you can see in the video. Once I set FPS limit to 150, everything is instantly fine. Bellow that the suttering occurs. Core parking is forcibly disabled in the windows registries.

After like 10 game restarts it finally works without stutters. I really don't understand what happened.

For me it looks like Vsync. I see it's disabled, but maybe active over nvidia driver? It would also explain the parking.

No. I have set "leave the decision to the 3d application" for everything.

Today i turned the game again and the issue is back. Seems like it happens randomly. Something is parking. But I don't know what because all cores are unparked.

This may or may not help but see especially around the 16min 16sec part, I have affinity set to FF and DCS runs way smoother (12700k CPU)

You think it is possible to overflow 24GB VRAM and 64GB RAM in main menu?

With a 144Hz Gsync monitor you should set the Frame Limiter in DCS to off (all the way to the right) then in Nvidia CP set a frame limit of 144Hz to match your screen or perhaps 2-3 fps lower if you still see tearing. Turn Vsync off in DCS and NCP.
