I run my app at home which is only 1.3 duron and nvidia gef4ti and i get 60FPS, same on the machine in work which is a monster but only a gef4 mx440...........However a mate has run it and his FPS is 2, yes no typo 2.......thought he didnt have a compliant card but he says he plays q3 arena daily. Whats going on?

Sounds like a problem in your app...

If you want any more specific answers, you'll need to come up with some specific info. :)
How is anyone supposed to know what your app is, what machines it runs and doesn't run on, which parts of the code you suspect?

At a wild guess, I'd say the problem is in line 57.

;)

he has a slower AGP bus? less memory? more processes running in the background? different version of dx/ogl that's causing it to fail? not checking for failure? I dunno...

something is probobly being forced into software mode.
But i can't tell directly what it is, you need to provide more information, like system stats, more details about your program(what it does and how it does it) and so on.

I seemed to have such a problem with my Creative Contest 2003 demo, my PC ran the demo at about 20 fps (GF4ti4200), all others only got like 5 at most. I still don't know why, after a driver update i got the problem too.

Was only looking for a general yes that happened to me(thanks tree penguin, i updated your rating)

2 of the most common cases for this are:
- selecting unsupported pixel format (PFD)
- using some functionality that is not HW supported (example : aux buffers on gf1)

The first thing you should do is to install a newest verison of drivers you can find (usualy some beta). And do a clean install ( uninstall, clean, install ).

If that doesn't work, then dig into the program gradualy disabling components.

Ok, you kind of set me to solve that problem i had and i found it had something to do with my vertex shaders (one of them actually isn't visible at all). When i disable the most complex shader (the water shader) it runs at 15 fps, when i enable it it runs at at most 4 (even if i don't have any operations (except passing variables) in that shader). I guess it must be my implementation or something.

That's all i know, sorry i can't help you any further. Thanks for the rating!
