something I noticed, is that when i try to spin around with 2 or more viewports open, my CPU usage jumps to 30% (up from 3 or 4% when ideling). Using one viewport it stays pretty much around 3-4%...probably the highest it jumps then is 7%.

That doesn't seem right.

So the hardware acceleration becomes disabled when using a second viewport. Reverting to an older driver perhaps can help...

Do you open the second viewport in a separate window, or switch a panel to a viewport?

I tried both opening in a second window and switching to a panel in a viewport.

I'll try going back to an earlier driver tonight to see if that helps anything. Although my card was only released in November so I won't be able to go back very far because the drivers for this card are custom by Sapphire. So before the release of this card no drivers exsisted for it. We'll see if that helps though.

With my experience, there is no way to fix it with my card.
I've tried all drivers when after I purchased it.
I don't know this whether AMD's fault or NL's fault.
But I hope that NL team should more opengl test with these cards (radeon) when they release 2.0.

I have not had a chance to roll back my drivers yet, but seeing that I had this same problem with an Nvidia card I do not believe drivers are the issue. Having said that, I never had this issue before I switched to Vista.
regardless, I will try rolling back drivers when I have time because I do not want to rule out anything

I was able to get feedback from Next Limit support, although I was basically only able to get get the general "make sure your graphics card drivers are the latest"" response. At the time they were the newest available, which were probably 4 weeks old at the most...I do believe they were actually only 2 weeks old though. I sent him/her a link to this thread so that the customer support person would be able see the fixes that i've alredy tried. Hopefully I will be able to find and answer to this soon. :-\
