No problems with the video card under other circumstances... games, Maya, etc. After much experimentation, it appears that the hesitation only occurs under the following circumstances:

- Pan, zoom, or rotate a viewport. (Smooth!!! Instant updates.)

- Immediately move the cursor (ie. in one motion: release the mouse button after the viewport change and at the same time move the cursor).

- The cursor "sticks" for a second or so after the completion of the view change.

It's almost as if MoI is intensely busy for a very short interval immediately after the view change.

Not a big deal, though. I can work (uh, play!) around this issue by changing my behavior just a wee bit.

Hi John,

This definitely sounds a little weird.

I'm still not quite entirely clear on what part actually "sticks".

Do you mean that the actual Windows system mouse arrow cursor itself freezes on the screen and does not move anywhere?

Or do you mean stuff that is drawing inside MoI, like a line that you are drawing, or selection highlights, etc.. seem stuck?

Does it happen when you are in a totally blank scene like at a fresh start up of MoI?

Solved it.

"Display pointer trails" was enabled in my Mouse control panel object. With pointer trails enabled, the mouse cursor "sticks" momentarily to each viewport boundary while the navigation icons fade out/in.

Disable "Display pointer trails" to fix this issue.

Thanks for your patience!!

That's good news John, thanks for reporting back here on the results.

I haven't had a chance to dig down into that other display artifact yet, I'll try to look some more at that one after this next beta is out.
