Hi Lar_q and KnightPT I also had major problems with Divinity 2 - very poor performance in menus - inventory about 5-6 FPS and in game (all settings set to medium and resolution to 1360x768) 25-40 FPS. But now its all gone - some forum user proposed to use russian crack - yeah it's lame I know, but I tried it anyway and... everything works perfectly now! All settings set to max and I still have solid 60 PFS and o stuttering in menus.. I have original Polish version of D2 so I don't know if I gonna use this because it may cause compatibility problems with my savegames. Still maybe it's the problem with protection used in D2?
...and I won't say a word, that having original game I still need to use crack to fully enjoy game
