Welcome to the new Photo/CAD/Graphics forum
well, thread is newer, so high hopes someone will be able to pop up with similar problems and possibly a fix.Not that i am aware of on the Surface, but on a stationary rig i usually just update the graphicsdriver and DirectX if it's not up to date. It 'can' resolve such issues.
There should be other users of AutoCAD or other CAD/solids applications on this forum so let's see if they will reply. I just do regular 3D modeling, animation and rendering on my Surface and i have not yet run into any issues with my software.
Yes I've done both pre (stock) and Intel newest drivers. No difference. I used the driver uninstall software off guru3d.com site to make sure drivers were fully uninstalled.Have you tried the newest Intel HD 4400 Driver? It has better OpenGL support...
