Sudden Framerate drops on overpowered PC

[plutomaniac]

If the issue is that the game dips to 30 sometimes, this is normal with vSync enabled. A specific event in-game could be "heavier" for your graphics card and temporarily dip below 60 and thus automatically to 30. Try disabling vSync or if you have an Nvidia card check Adaptive vSync at the Nvidia control panel. Adaptive keeps vSync on at 60 frames and disables it when it dips below that. So, if you go to 58fps at some point in won't jump all the way down to 30 (noticeable stutter when that happens) but instead it will disabled vSync momentarily until you are able to play at a stable 60 again.
