During 3dORBIT the frame rate is slower (about 10 times) using hardware acceleration (sort of moves for a bit then stops) and slows down allot more when the mouse is moved. It is unusable with hardware acceleration on. Also it doesn't degrade to wire frame with shading is turned on.
The performance is the same with the graphics card set to the default values or optimised for speed.
I've searched for new Heidi drivers but was unable to locate any.
