Dexterous,
Thanks for the reply and items to try. Unfortunately those steps did not resolve the issue. The intermittent stuttering/FPS drop is still there.
Also to note, which is more than likely not related is the fact that GPU-Z no longer appears to function correctly. It will report only 63 MB of VRAM being used. This is using version 0.8.0 and 0.8.2. All other VM versions (8,9,10) this works correctly.. well correctly displaying VRAM usage and approx GPU load.
Regards,
Nathan
