have you tried reinstalling the game? you most probably have but still...
and also is the game fully updated?

if action is what you want you can try out both Trine 1 & 2
Capsized is pretty good too and if you are in the mood for something retro try out Captain Claw

you can try to run the game in compatibility mode if you haven't already

should have posted in primary games discussion or any platform's section

The Witcher 2 is pretty good the combat is engaging and challenging but not insanely hard like Dark Souls
Diablo 3 is nice too
if you wanna play something a bit old then you can try the 'Neverwinter Nights' series and Dungeon Siege (only the first game was good the sequels were a joke)

pretty much al the good games have been mentioned
i will suggest you to try the 'S.T.A.L.K.E.R.' series and Metro 2033
