Works -- mark as solved that is/was annoying

its not solved, no other opengl application or game, (apart from the Realtech VR app) exhibits this problem, so it should be fixable application side.

Even with changing the Threaded Optimisation settings, I've found that XP Guest OS's wont work properly with the latest nVidia drivers (Windows 2000 and Ubuntu are fine though).

It hangs are the Welcome screen and then BSOD with : DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS

The offending file seems to be the Intel graphics driver (intelppm.sys)

You have one of those optimus setups?

its not the nvidia driver if its occuring in the intel system files.

Turning the threaded opt to "ON" worked perfectly, first time. Saved three virtual machines our family uses that are very important to us. Thank you, squall leonhart!

Thanks for the solution to deal with the appcrash generated by "nvoglv64.DLL" , turned the switch to 'ON' problem gone

nvidia have resolved applications unsafely creating display threads on the driver side.
