This is the results I found when trying to compare some graphic cards. The tests where performed 2003-feb on a Compaq 2.26GHz, 1024MB RAM, Vsync off, Windows XP. Latest drivers and some older where used and compared. SPECViewperf 7.0 was used and Cadalyst benchmark 2001 for AutoCAD 2002.
In AutoCAD the following settings where used except that the Driver were changed:
Here are the results from the tests and I let you draw your own conclusions. I cannot explain details of it but the conclusions I draw are these that try to use the newest possible working driver to get the best performance. I tried software accelerations in the Cadalyst test and I didn't let it go for all but in average it took 4 times longer to finish the test. If you use the Parhelia card you should defenately use their hdi-driver for best performance. When it comes to the PNY cards it doesn't matter much if you use AutoCAD's or Nvidia's driver when it comes to performance in these tests.
