Yep Exact same issue with my new 3080.Frametime a bit jumpy and the fps stopping at around 138 fps.(had to use the latest driver because of the 3080)
Il uninstall the game for now till it gets fixed.
I tried putting a frame limit of 137 with Riva tuner (because the game inherently stops at 138 for some reason) and its sooooo much smoother.Frametime is 95% of the time at a constant 7.2-3ms
I tried putting frame limit of 137 with nvidiaCP and the frametime was * again.So the Nvidia limiter/reflex is not working correctly. There's something up with the drivers for sure.
