Quote - Now about the dodgy drivers...I wonder why my Maya, Max or Vue doesn't have any problems.
Those being 64bit apps also.

Poser Pro (the previous one) doesn't have any problems with Ati and opengl nor has silo. Though those are 32bit applications.

How on earth have those developers managed to do it with the dodgy drivers?

Or maybe they're just not using opengl at all :/

This is not so much about 32 or 64-bit. There are many OpenGL features, few applications are using all of them. Different applications use certain features in different ways, or to achieve different things. Newer versions of the same application might use newer features, as older features become deprecated or poorly supported by hardware vendors. That's why one application might suffer from a driver issue, while others don't.
