Ok, so i've bought an old Dell Optiplex GX260 (2.4ghz Pentium 4, 512mb RAM, 160gb HD, CD/DVD) to convert into a Windows 98 gaming machine (Windows 98 SE installed).

I've coupled the system with an ATI Radeon 9600XT AGP card, 256mb. Direct X 6 and Direct X 9.0c installed.

Everything runs 60fps smoothly, mostly. However an odd issue is plaguing my setup. When playing Star Wars: Episode 1 Racer, every 1 second it seems, there is an ever so slight jump in the graphics, like a jerk. And also, a few texture issues at the beginning of each race, especially when the camera pans. The jerk happens both over VGA and DVI (using a DVI to HDMI cable).

The game still runs at a perfect 60fps, but every 1 second, that jerk happens.

Latest Omega drivers installed for the Radeon, mobo bios updated to the latest, A09. I have also tried the ATI drivers hosted on the AMD site, and the jerk still occurs. I have also tried the machine on 2 different displays. Same results.

Any ideas what might be causing this? Will installing a Nvidia GPU solve this issue? Any info you guys can give would be most welcome. Thanks in advance!

Matt

I haven't checked the temp yet, i'll do that. I did put fresh thermal paste on the gpu heatsink + fan, and the fan runs smoothly, so it can't be a temperature issue surely?

As for the drivers... I had no idea. I suppose an option, if the temperature is ok, is to get a Nvidia card. Also, I've read around that increasing the AGP bus voltage ever so slightly could help also?
