Hello I installed the game last weekend on my new gaming laptop. It "froze" during the intro movie but then worked correctly after I hit escape. When I exited the game the screen went awash in a weird yellow pixelated pattern that only cleared on a reboot. I checked graphics drivers in GeForce Experience and found I was up to date. I did notice that Grim Dawn is on the supported games list but the applet is not detecting it though the parent folder is in the search list. Does anyone know what file GeForce is looking for? I had to create a empty text file with the 32bit executable name to get GeForce to find Elder Scrolls Online on my system but my google foo has failed in finding similar for Grim Dawn.

Best thing to do is not use GeoForce for the game. Causes more problems than it's worth.

Yeah, those softwares are rather advert, made to sell hardware, they are not seriously done.

Just install drivers and none of the added software. Games run best that way.
You can find out how it's done on the internet. Good luck!
