Continues to Run fine for me graphix wise with new 1.6 patch but I've just noticed that Melee no longer works when riding an Elephant, flipping a vehicle over no longer works unless you charge & run into it,
changing the key to any others makes no difference.
Thank you for reporting this. I will pass it along to the team. In the meantime, please try verifying the game files to see if there are any damaged files. If this persists, please be sure to submit a ticket to Support with your msinfo and dxdiag. You can submit these files via "my questions" here.
