Geforce + high IRQ

5th January 2003, 17:17

specs:
P4 2.53 Ghz
512 Mb PC3200 Corsair DDR (thx Duron)
Asus P4PE
Gainward GF4 Ti-4400
Liteon 16x DVD
Liteon 52x writer

OS: Win2k Pro

My geforce is on IRQ 16 (together with usb controller). Could this be a problem? In games (UT, UT2k3) I have good fps, but I have random framedrops and I don't know why. Could it be the high IRQ or could it be because I use the onboard sound?

Any advice?
Is there a way to set the IRQ for my geforce to 9 or 11?

high IRQ does not relate to slow/high performance afaik

so the performance drops are due to other things
could be your HD being accessed for data..

I thaught that also, but wasn't sure. I think it has to do with onboard sound, because 3d mark runs without framedrops (no sound is used here)

that sort of thing is also a symptom of some problem with drivers. I can do two clean installs of windows and drivers on the same machine but in one case it will have the frame drops you have for some unknown reason. I dunno what it is. The IRQ thing isnt so much a problem really.

I will do further testing after my exams, but setting the aperture size on 256 instead of 64 helped, I think... don't have much time to test, but I have the impression it helped.
