No worries, I hope nobody else experiences the same crash. 
I’m curious, what’s the difference between these three in actual results, both in the graph and visibly?
- setting the Max FPS limiter to 30 and “Fast” VSync in Nvidia CP, but turn on Sim VSync.
- setting the Max FPS limiter to 30 and “Fast” VSync in Nvidia CP, but turn off Sim VSync.
- setting the Max FPS limiter to 30 and “use 3d application setting” VSync in Nvidia CP, but turn on Sim VSync.
For me all three perform and look about the same, both in the RTSS frame time graphs and from what I can see by my eye. (Any differences in the graphs are minor, and make no visible difference.)
