I can't even get past the main menu ever since the update was released two weeks ago, and Rockstar Support has been completely useless in doing anything to fix the problem.
Yeah, its been bad for many from what I've been reading. I swapped to the newest Aug1 drivers again and after the latest small patch yesterday it was running better in the sense that I didn't have a random crash/freeze in 30 minutes. I also noticed that the game was using about 500mb less video ram than it had been on the weekend. That said, PC version Online was mostly horrid last night. Horses were useless and wouldn't move properly, spazzing out and animal spawns seemed broken again.
