The easiest fix is to replace the card with a compatible one. I'd still recommend using the process explorer. It has a GPU tab to examine GPU usage. As it is not supported by PTC I don't see any resolution to the problem unless you happen on a compatible driver. Depending on the Machine brand the driver from Intel may be incompatible.

Typical stats as part of identifying performance problems:
