Thanks for the update and trying to see if the latest drivers fixed the issue. Would it be possible to provide crash dump files so that we can figure out if the driver is crashing or if a hardware hang is occurring and the GPU is getting reset.
If its a crash, there should be a windows message box saying this application has been forced to close. In that case, it should be possible to get a .dmp file following the steps below:
1.Create the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps
2.Create a DWORD called DumpType and set it to 1 for a minidump (smaller file size) or 2 for a full dump (much larger file size)
3.The dump file will be saved in the %LOCALAPPDATA%\CrashDumps folder.
4.Open the .dmp file with Windbg and type !analyze -v and start looking at the failing callstack.

If the GPU is hanging and getting reset, you should get a popup in the windows taskbar (attached). In that case, please send us any .dmp files that exist in the C:\Windows\LiveKernelReports\WATCHDOG\ folder.
