After the update the freezing cleared up, but the moment I saved and re-entered the game it returned. It is so bad it is next to impossible to use the mouse to exit the game from the menu. The texture issue never left.
The irritating part about all of this is that my brother was having the same issues (minus the freezing, but he had low frame rate) and all of his issues cleared up the moment he used the current patch. Both of us are using identical 5850's. The only different being my CPU is Intel Core 2 Quad, and his is AMD's Quad equivalent. Now while I know that would cause some differences, I wouldn't imagine the differences would be nearly on this scale. It is demoralizing to see him playing it (he stopped, saying he wants to paint models, but I'm guessing it's because he doesn't want to play the very same game I'm having issues with). I'm at a complete loss as to what to do about it and have looked over Steam forums, and this forum, trying to find solutions and either the ones I find don't apply or out right do nothing to change the issue. So I've made this thread as a means to ask for help related to my particular PC issues, so I can hopefully better solve this problem.
The things I have done so far are this: I uninstalled ATI everything, used Driver Sweeper (in Safe Mode) just to make absolutely certain, and installed the updated patch (identical to the patch used by my brother). I have overclocked and copied the Catalyst settings of my brother. I have created the AppData folders (which created the two files related to the folder creation) and I have rebooted the computer more times than I care to recall. I also re-installed the game, which gave me the most success, though immediately reverted to every problem previously encountered upon restarting the game.
To say I'm at my wits end is an understatement and any, and all, help would be greatly appreciated.
