My install went fine and it was work fine before the install. I suspect this latest version (419.67) for Windows 10 is not compatible with this latest version on t_Rex.
I have 3 Windows 10 rigs, and I have only updated this one. The other 2 are working (well creeping along really slow due to such high difficulty levels).
I can install the earlier version of nVidia drivers, but thought you might want to take a look at whats causing this.

419.67 should be working fine. Someone from Discord had the same issue and then said it was fixed by "properly" installing the new drivers. Not sure what that means but I suspect the driver update screwed something up in the system so they had to clean everything up and reinstall the drivers.
