I'm going to test a cracked version of 1.2, just in case. In order to make certain, I think we should post our crashes and details on things like reproducibility, and if so, how you reproduce them, exact description of the crashes, computer settings, driver versions, how often they occur, etc My crash happens after about 2-4 hours of extended playtime. My computer makes a beeping sound while immediately shutting down and half a minute later restarting. The crash is not reproducible intentionally as far as I know, and happens to nother game I own. I use the 260 NVidia drivers. I have tried everything posted in this thread, minus CTD solutions and anything solution involving ATI cards, and have read it entirely, I think. I posted a solution before which only worked on some computers (Uninstall DX10 / 11, Install DX9), but for me this only extended playtime to 2-6 hours, max. No forced NVidia settings or ENB Series where placed. No mods have been placed either. I have run 1.0, 1.1 and 1.2, to no avail. I have tested these versions across Steam, DVD and Pirate installs, except 1.2 on the latter. The only Long term solution I have managed to find is running the game under Wine in Ubuntu, but that's not a solution for most of you. My system settings are: Intel Core i5 2.70GHz Overclocked Windows 7 Home Premium 64x / Ubuntu 11.10 32x 4GB RAM 1GB Nvidia Geforce 250GTS 1TB Hard Drive I think we should record each crash and hardware report and relate them to each other and categorise them. This may help pin down the problem, since not every user is experiencing the problems, otherwise this game would not have been received so well. I will copy each post regarding crashes and hardware and categorise them myself.
