Physx GRB (GPU rigid bodies) is broken on Titan V (volta) was OK with Maxwell.. #74

Hi, had Kapla demo from SDK compiled from original 3.4.0 release and worked nice on a GTX 970.. upon changing to a Titan V sample doesn't work correcty.. upon starting all objects fall below the floor.. the same error is present also in Snippet GRB sample.. so I downloaded lastest SDK here (3.4.2) and recompiled Kapla demo and same error is present still.. I notice more clear errors are shown upon pressing space key for shooting objects to the scene:

This can't be fixed by myself as GPU portion of PhysX is still closed.. log running Kapla and shooting:
