Also gonna jump in here and say iv been having the exact same issue since the patch came out, having had no issues at all before hand. Iv tried reinstalling graphics drivers, making sure windows is updated, validating game files, even changing my cpu clock incase it was overloading as its an intense cpu game. But nothing has worked. Restoring the game via its client worked temporarily but when i played a few hours later the issue came back.

Really hoping they address this as it seems to be something out of our control. Iv played on directx9 a bit but even that can be prone to crashing from time to time.
