yes, it goes back to normal, another thing is that I have realized without the active vsync it seems that it uses 98-99% of graphics but activating the vsync does not use it as it should, that is to say when falling frames could use more percentage, an example would be that it goes down from 60fps to 50fps and the graph is using 70% for example, thus being able to use 99% and give more frames. the frametime is also very unstable, it varies a lot.
edit Regarding what happened with the resolution 2k happened to me changing graphics, resolutions and limiting in rivatunner, perhaps a conflict was created in which the fps were limited, although in rivatunner the limitation was 0. I am doing verifications with rivatunner and the frametime is stable and limiting from there is controlled a bit, although I still do not understand what happens sometimes and sometimes not …
another test: vertical synchronization activated low low of 60fps up to 30fps in certain zones, with the vsync off this does not happen, I think that the vertical synchronism works badly. What I said before blocking frames at 2k is also fixed when you return to the menu and re-enter.
