I'm pretty dissapointed in the lack of graphics settings, they keybind thing I can live with but I never thought CDPR would do that. Seems like another case of playing to the consoles again. The crash/freezing issues prevail however. Last night I managed to keep it running for a couple hours with the driver set to "Prefer max quality setting", thought I'm thinking it's less likely a video driver problem. It's a very common problem from the look of the steam forum and CDPR forum.
Overall I kind of expected the game to look and run better, granted the 2nd map is pretty big with many places to explore, but it does only look like a slightly modified Witcher2. I'm enjoying the story though.
