Wow nice helping here.... noot...

Well this seem to happen pretty often with rtx cards.

Try to limit your fps and the Hz on your monitor in the config files and in the nvidia tool for the game. Your gpu probably tries to achive limitles fps even if you cant see or expirience it xD.

Sometimes it seems that graphic cards run at maximum if you dont tell them not to do it by limiting it yourself.

This problem needs to be solved by the devs and is probably related to the unity engine too.
