Common crash in driver : Access violation in nvwgf2umx.dll

Hi,

A DX11 game we’re working on is getting the following error in random places in our app:

Exception thrown at 0x00007FFE38EB70A7 (nvwgf2umx.dll) in GLTD.exe: 0xC0000005: Access violation reading location 0x00000000189E5000.
Unhandled exception at 0x00007FFE38EB70A7 (nvwgf2umx.dll) in GLTD.exe: 0xC0000005: Access violation reading location 0x00000000189E5000.

Searching Google for “Access violation in nvwgf2umx.dll” shows this is a very common problem with no apparent
solution. I’ve tried narrowing the problem down, but it appears to be very time sensitive.

Anyone know of anything I can do, so I can work around it?

This is the same on a 1050TI and a 1080. Both with the latest drivers (416.94).

Thanks,

Steve.

Ignore. Fixed it. Driver was copying from a mis-sized vertex buffer, my fault.
