[Insight-users] slow imageviewer

[Reinhard Hameeteman]

Hi Todd and others,

I agree that the card isn't a fast one, but I'm not asking much of it. All I'm doing is
drag a crosshair over an image. It seems to me that this should be a simple task.

Regards,
Reinhard

This little app looks like it reports and test opengl in various modes and extensions.

http://www.realtech-vr.com/glview/

3DMark is a Direct3D benchmark, there are not many opengl benchmarks, but I found this
one.

http://www.glexcess.com/xsmark/

Scores from their database:

~22k 6800/X800 class
~13k 6600/9800Pro class
~8k Ti4200 class

The 7000 series would come in around 2k, it is not a fast card. So it may be running in
hardware mode, but you may be asking too much of it.

Todd

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)!
