PhysX CUDA uses a different method of solving constraints than PhysX CPU....whereas PhysX multi-threading should yield the same result as PhysX single-threading...so whether or not to use PhysX CUDA depends on a case-by-case basis, if it's producing acceptable results. It's the only black-box solver in tyFlow (black-box meaning I don't have access to the source code, because NVidia hasn't released it). All other GPU/CUDA solvers in tyFlow should produce the same results as their non-GPU counterparts...so it's safe to always use them in all situations.
