21.5 iMac GeForce 9400 - Refresh Rate - SethWillits - Feb 23, 2011 02:11 PM

Anyone have a 21.5" iMac with GeForce 9400 10.6.6? Playing this movie I only get about ~30 fps playback according to Quartz Debug. CVDisplayLink callbacks also go at only ~30 fps. What gives? Anyone know if this GPU is really that sad that it can only muster 30 fps?

That's really odd, I get 60 fps on my 1st gen MacBook (Intel GMA 950, Core Duo)

I get 60Hz according to Quartz Debug playing that movie on my 9400M (Mid 2009 13" MBP, on the 24" ACD. 10.6.6)

Well this is very odd. Sad

I tried googling to find if this was a known problem, but I just get a bunch of noise. I really need to find someone with the same hardware.
