Reguarding HairWorks. Did you had a Chance to view the files before commenting? They are similar to APEX files (.fbx and .apx) and they just like APEX get a boost using NV cards but it should work on all just like APEX. So suport for HairWorks should be same avaible just like it is for APEX reguarding “hardware”. So there should not be trouble supporting it.
And YES. APEX clothing can run on non-Nvidia gpu’s. If someone is usnig one they get a slight boost in framerate but it does not prevent other from viewing them. Same with destruction. Only turbulence would require some fixing.
