Yes it does, two completely different OSes, two different drivers. The point is that nVidia has been getting sloppy with their drivers for quite some time now.

Absolutely agree. I know this is about OpenCL, but I've had terrible problems with recent NVIDIA OpenGL drivers creating holes in meshes in Studio and Blender viewports (more than just holes in Blender—an indescribable mess). I've reverted to the drivers that came with my computer, which are now about a year old. The most recent drivers I tried did not have the holes, but crashed Studio frequently. These are for cards that are supposedly professional. However, I'm wondering if pro 3D applications use OpenGL for their viewports. It's something I know next to nothing about.
