Display performance is slow with multiple ogl views open
Shaded mode display, the animation mixer, the animation editor, and other OGL views seem sluggish or exhibit poor performance.
Cause
It is possible you have not turned off the Vertical Sync option for your graphics card.
If this option is not disabled, then your maximum refresh rate will be the vertical retrace frequency divided by the number of OpenGL views open. For example, if you have a refresh rate of 85Hz and five OGL views are open, the best refresh rate you could get would be 17Hz.
Solution
In the Advanced Display settings for your graphics card, turn off the option to synchronize buffer swap to the Vertical Sync. It should be set to something like Always off or Off by default. You will have to restart XSI.
