I Finally found a solution to the stuttering in fc25 for pc.

Lowering resolution / lowering details... not really a FIX...
On my system game runs bad at 4K, but very smooth at 1080.

So not a fix at all.

Problem is EA side not optimizing for higher resolutions.

Running smooth at 4K would be a real fix.

(i9-13900K, 4080ti, 64 GB ram.... so let's no kidding. I can run Cyberpunk2077 full details 4K butter-smooth)

And what you suggest, you can easily do it with Nvidia settings. No need at all of Rivatuner and other stuff.

I did the same you did with NV inspector, but still can't run smooth 4K.

Again, as you also say, NOT a fix.
