Our team are aware of the issue and are looking into this. In the meantime, FusionPhysx and Narxes081206, I'm sure you have already but just to be sure, have you ran through our troubleshooting guide, being sure to verify your game files, update your drivers and OS, make sure you don't have any unnecessary background programs running, and reinstall supporting software such as DirectX?
As said though, we're looking into it, so we'll post again in this thread if there's specific troubleshooting we'd like you to perform to help with our investigation. Thanks again for your updates!
