I used the uninstaller. Then reinstalled with the same outcome. I ended up uninstalling then installing the 2020.4.1 with zero issues. The 2020.5.1 did give me 10 to 11 fps on the 2018 tomb raider on the most gpu intense settings from a avg of 13 to avg of 21 to 22. 2020.4.1 was just a few fps less being 19 avg
