I have 3dsmax Design 2012 installed, with the hotfix applied. My GPU is an ATI 5750, and worked smoothly with 2010 and 2011.
Eversince I installed 2012 (before and after the hotfix), whenever the files get polygon heavy I have the following problem: when I perform a viewport operation, such as pan or orbit or zoom or select, there is a lag of 1-2 seconds before I can do another one. This happens ONLY on perspective or camera views, shaded or not. The same thing does NOT happen on top or front/left/right views even there may be 8 million polygons on a shaded or wireframe view.
It seems weird because if for example I do an orbit operation on a perspective viewport, it is really smooth on files of millions of polygons. but when I release the mouse button it freezes for 1-2 seconds. I presume it must be caching data on the GPU or something, but I can't be sure about that.
I have the latest ATI drivers (11.5 suite) installed and max is using the Nitrous drivers, although the same thing happens with Direct X and OpenGL (they are a bit slower though)
My question is: does anybody experience the same problem? Is it an ATI problem? Should I try an NVIDIA card?
