WindowsXP

it depends on your drivers!

I had a P3 667 with Win2k .... my Demo runs with 120 FPS
New Maschine Athlon 1.4GHz with WinXP 12 FPS YES 12!!!!!

Unfortunatly, due to my 3Dfx based graphics card and nvidia''s decision to only support American customers, the last manufacturer driver appear in late 2000, the windows 3Dfx driver does not appear to enjoy OpenGL for some reason!!!

and i have the latest of those, dated 3/10/2001!!!

Still no joy!!

IIRC there were new 3dfx drivers out less than 2 months ago

Where are they available from ???

anychance of a url??

www.voodoofiles.com has the latest official voodoo drivers, and tons of third party drivers as well. They also have a WinXP compatible driver.

Nope, it kinda killed my computer!!!

I have upgraded to XP recently, too... and now all my OpenGL apps run at 1-2 fps as opposed to 100-200 fps. I think this is a driver problem.

My graphics hardware is a TNT2 Ultra using an nVidia chipset. Upgrading to the latest nVidia detonator XP drivers (or the card manufacturers own XP drivers for that matter) result in the same problem.... that is, XP crashes and I am forced to rollback to the previous drivers. Tracking through the error log I see that (in both cases) XP reports the problem as being a potential infinite execution loop in the file nv4disp_dll, or words to that effect. I might have also got the dll filename slightly wrong, too... :-)

Has anybody else experienced this and managed to find a driver release that fixes it?

Thanks,

Im starting to get the feeling this thread should be on a microsoft site somewhere!!!

I downloaded the Detenator drivers and everything works fine for me. Before that OGL ran at about 1 frame per 10 seconds.

The problem is that XP''s default OGL drivers do **NOT** support hardware acceleration. If you are distributing OGL apps, you need to make sure you give your customers access to GLSetup, or some other means of getting the latest drivers for their card. Just another reason I don''t care to ''downgrade'' to XP.
