Hi guys, I have an easier solution here, 1) Go To your device manager 2) Uninstall every Human Interface Device you dont need. Only leave the mouse and keyboard 3) Run the game smooooothgekkegast93

The game was running absolutely slow too and then I tried this and now the game is running everything on High and super smooth! Thanks man!
