I've had problems with any 3d accelerated video windows being open in firefox etc affecting games performance wise when in the background, not only if the video is running, but even if paused or stopped- on a 4890. IE anything using GPU accelerated flash

just installed Live Messenger 2011 - and happened to have FRAPS running - and with Live Messenger open its showing in that windows a FRAPS fps figure - does that mean its also using GPU acceleration ? and would it affect games if running in background ?

don't remember Messenger ever showing a fps figure before ?

cheers, Buckster
 
Yeah I get the same with windows live mail and movie maker, never notice it effect games performance. Checking GPU usage when these apps are running shows 0-1 % usage so it won't effect gaming.
 
ah ok - thanks for reply

I'm going to turn off flash acceleration as it bugs me that if I want to listen to news in background while playing a game (yes a bit weird I know) it can affect my frame rates by as much as 30% in game :( never used to be a problem - only since the ATI drivers supported hardware accelerated flash
 
I figure the powerplay clocks have kicked in and are running in lower power state speed when running your app and have not gone up to full 3D clocks when gaming, powerplay was a problem for me and my 5870 as well.
 
Sadly if you have any 2d gpu accelerated content running (including in game) then amd cards use the 2d clock speeds i.e. if you're running a 3d game then open the wrong menu then the card, which has just had it's workload increased, will slow itself down.

Never bothered checking if it was driver or hardware based, because I assume no one could design hardware so ineptly.
 
Seems amd fixed the 2d issue several driver revisions back, but they still won't used 3d clocks if you start some gpu accelerated video (flash, vlc, even ff4/ie9). Still, with amds driver record it should be fixed within 6/9 months =D
