I am running into similar problems. When I run the Clothing Tool. I get the message: GPU compute capability 6.1 is not supported by this version of PhysX. Update the driver to the latest version. As far as I know I should have the latest version installed. Also I have a GTX 1070 installed with the latest drivers. As far as updating the PhysX driver itself, I’ve looked at all the available NVIDA downloads and can’t quite figure out if any of them contain the latest drivers. I need to use APEX assets so any help with this would be appreciated.
