I have updated my video driver.
I first moved from Org to Thunder Bluff (thinking it was a lag issue).
then
I removed my 2 key maps for High and Low Video Settings for swap. When I remove them, my swapping from window to window is almost seamless (how I remember it before the patch).
However, when they are enabled, it seems about a .5 second delay when swapping.

Here are my High and Low settings. Note, I have also tried the newer ones from the sticky, still no success.

I feel something needs to be removed because of the patch.

Any ideas?

thanks,
Acid
