[Insight-users] slow imageviewer

[Karthik Krishnan]

You can run glxgears on windows through cygwinX (although the cygwin emulator does not seem to give you the true numbers) and is 20 times slower than native windows FPS numbers. There's a 3D Mark2005 demo version that you can use on windows though to test your graphics card. I wonder if anybody knows of a way to compare graphics performance platforms (other than running Unreal or doom)!
