yes, you can see the cpu and gpu usage up
I have turned off frame generation and put dlss on ultra performance for big fps and capped it to 60, feels like garbage, capped to 75, still feels like garbage, capped to 90 feels a little bit better but it still feels not smooth, capped to 120 and it became smooth again
I tested The Finals and using their in game cap, 60-90fps caps all feel not smooth only when i put it 100 and higher it becomes normal and smooth
Not really seeing much wrong in the video except maybe one or two stutters.
You mentioned earlier that you tested with 60Hz, but I honestly have a hard time believing that you did (and it seems like you only tried capping to 60fps, which is not the same thing and does not do anything for this problem). Try actually setting your G70NC to 60Hz and try again.
And if you really did test with 60Hz and did not like it, then frankly that's just the way the game behaves, at that point.
Without VRR, a high refresh display running at 60fps will feel infinitely worse than a native 60Hz monitor without VRR. Even with the help of VRR, a high refresh display running 60fps will still probably feel worse than a native 60Hz monitor, providing a less smooth experience overall.
It doesn't matter if the fps counter looks stable or not. You can be pegged constantly at 60fps and things will not be any different. It's just how things are - that's why some form of VRR is mandatory for high refresh monitors, even though the two are two separate things.
i am on the latest frimware (1604) and also latest nvidia drivers
Do you by any chance know which setting is preventing me from changing them, maybe i have to switch to HDMI ?
Switching to HDMI sounds like the right idea. Those Picture Clarity settings are TV oriented, and the Samsung panels are originally HDMI only (G70NC being some sort of modified QN90B/QN90C panel), they just added a DP for convenience on G70NC.
Do you still have one of those features (Adaptive Sync or VRR) turned off? I wouldn't be surprised if them being on will automatically change the right Picture Clarity settings choices for you.
