I played this game quite a bit and enjoyed it very much (WIndows 7x64). It's been a few weeks since I played it and now when I try the screen goes black, the large Two Worlds logo appears and at the same instant it crashes for an unknown reason. I tried changing compatibility settings, running as administrator, removing the PhysX.dll and everything else I could find as a suggesting but no luck. None of those things should have mattered anyway because it worked fine before. If something changed with my system I haven't the faintest idea what it is or how to go about figuring out what's causing this crash. Any solutions are greatly appreciated as I would like to get back to playing the game. Thanks

That is odd. My best suggestion right now would be to back up your savegames and then try reinstalling the game. The saves are probably located somehwere in My Documents, but if you have trouble finding them there are many threads in the GOG forums about possible locations. Sometimes they are placed in a virtual store location, for instance. Two Worlds is a recent enough game that my guess is they go to the Documents folder somewhere though.

Same thing, I had a quite high level, nice weapon and for the last 6 months almost have forgotten about the game because it started crashing in the beginning. Newer drivers for nVidia might caused this, I installed older, no results. Reinstalled few times the game, nothing.

Try installing the NVIDIA PhysX Legacy System Software. Two Worlds needs older PhysX files that are no longer included in newer PhysX versions so it could be that a game/driver update has updated your PhysX.

The Legacy version installs alongside the normal PhysX version and won't be overwritten by future PhysX updates.
