What fixed it for me was after the yesterday's patch, I went to AMD Adrenalin to reset shader cache, repaired the game and moved game's options and save files to another folder, then I started a new game, that fixed it for me. Patch alone doesn't fix it unfortunately. I don't know how to reset shader cache on Nvidia cards but I presume it offers a similar option. And the save files are in the Documents>Dead Space>settings folder. We could easily fix it if we could share save files but as far as I can see everything is encrypted.
