Hi all, I just upgraded to win10, reinstalled Houdini after first crash but still getting crashes when using the view port with houdini both 16.5.2684 (which worked fine on win7) and 16.5.536. AMD A6-3420m apu radeon hd 6520g - pretty old.

Is there a display setting I can change in Houdini perhaps? GL/DirectX related?

Amd drivers are updated exclusively by windows update, so I'm not sure how find and install older versions for Radeon, or if it's a good idea.

Just ran both above versions in win7/8 compatibility mode from properties - same issue - crashing when rotating in view port or creating a primitive from shelf.

I was planning to do more Houdini twitch streaming, but his throws a spanner in the works for sure.

Any help, much appreciated.

The update probably changed the graphics driver on you. Unfortunately AMD doesn't update drivers for that GPU anymore, but you can try manually updating it from the AMD website, if you can find one (https://support.amd.com/en-us/download).
