Portal 2 patch changes performance

A patch was released tonight for Portal 2 that improves MSAA performance on all GPUs.

So I reran the timedemo on the top 2011 iMac versus top 2010 iMac versus 2010 6-core Mac Pro. GOOD NEWS: the 2011 iMac is faster than yesterday. BAD NEWS: It's no longer faster than the Mac Pro at 2560x1440. Here's the results:

At 2560x1440...
57 FPS = 2010 iMac Core i7 2.93GHz with Radeon 5750 (1G GDDR5)
83 FPS = 2011 iMac Core i7 3.4GHz with Radeon 6970M (2G GDDR5)
123 FPS = 2010 Mac Pro 6-core 3.33GHz with Radeon 5870 (1G GDDR5)

At 1920x1080...
85 FPS = 2010 iMac Core i7 2.93GHz with Radeon 5750
125 FPS = 2011 iMac Core i7 3.4GHz with Radeon 6970M
187 FPS = 2010 Mac Pro 6-core 3.33GHz with Radeon 5870

(Advanced Video settings used: 4x MSAA, Anisotropic 8x, Vertical Sync disabled, Multicore Rendering Enabled, Shader Detail Very High, Effect Detail High, Model/Texture Detail High)

Those are pretty great results! Sweet!
 
At 2560x1440...
61 FPS = 2011 iMac Core i7 3.4GHz with Radeon 6970M (2G GDDR5)

I'm getting the i5 but with 2GB GDDR5 on the 6970, but... whoa!

Nice, that means a 27" iMac with a 6970M can play any current OSX game at native resolution and high-to-maximum settings with decent framerates.

Makes the decision much easier. ;)

Thanks for the comparison!

I like that the i5 3.1ghz with 6970 1gb beats the
i7 3,4 ghz with the 6979 2gb with a few fps.

I already said a while back the i5 is more then enough for gaming and that the virtual cores makes more hurt then good when it comes to gaming.

Glad im seeing it in test now also.
