Dramatic drop in performance of a graphic card
I have a curious problem here and I am hoping one or more of the hardware wizards can explain.
I had a Radeon graphic card installed on a box running an AMD 2GHz processor and 2gig memory. This box died for some reason and, since I had to enable the services in short order, I moved the disc containing the OS (SuSE 11.2) and the card to a new box.
This has an Intel Pentium running at 1.7 GHz and 1 gig of memory.
Bearing in mind that the software (OS etc) and the graphic card is the same (same physical disc, same physical card) and even the monitor is the same I don't understand why the card is now giving frame rates some 5+ times slower than on the other machine.
On the original box, glxgears gave an average FPS rate of upper 3000 to early 4000. Now, it gives upper 600 to early 700. I kind of expected that I might see a little drop to account for the 300MHz drop in CPU power but this is ridiculous.
Monitoring the memory use during the glxgears run shows no swap activity at all so the 1 gig memory is sufficient.
