I’m having some strange issues with Rhino display which I’m quite sure are related to my graphics card settings. Details on the problem, my setup, and steps already taken follow. Any thoughts on potential fixes are greatly appreciated!
Portions of my viewport spontaneously freeze. Typically this happens in shaded mode, single viewport, perspective projection and in the middle of a command. While the majority of the viewport freezes, a portion acts normally and responds to pan/orbit/click mouse actions. However with most of the viewport frozen I am almost always forced to quit the command, at which time the viewport unfreezes, and try again.
In this image, in the middle of ExtendSrf when prompted to select a surface edge, almost all of the viewport freezes. The tiny squarish section of the viewport to the lower right of the Perspective viewport name is not frozen and will pan and orbit normally.
Rhino 5 SR12 64-bit
Windows 7 Professional SP1 64-bit
Intel Xeon E5-1650 3.2GHz, 16GB RAM
NVIDIA Quadro K2200, driver 220.127.116.1166
The NVIDIA 3D settings use the Global preset for Workstation App - Dynamic Streaming with Prefer maximum performance Power Management mode per these recommendations.
I haven’t been rigorous in trying to isolate the problem. However, it occurs independent of the file, view, display style (mostly), and command. It occasionally even happens outside of a command, simply navigating around the model. It doesn’t seem to happen in wireframe mode but it’s not very practical for me to use Rhino exclusively in wireframe.
I’ve changed the driver from the most current available to 340.66 with a clean install and re-established the recommended 3D and power management settings.
I’ve tried a few of NVIDIA’s other global presents but certainly not all of them. Thus far, no preset seems to be immune to this issue.
