PC: Odd Graphical Glitch

[PMB960]

So I was doing train runs with my Ranger(That mission is stupidly easy with Rangers),The Hulk when I noticed something odd. Every time Rouge(Ogg) would spawn I would see these strange purple triangles. Now I know you might think it is artifacting and a coincidence but I have a water cooled computer which right now is running at about 28C. Even playing PSU it only goes to 32C. I only ever noticed it when the Rouge(Ogg) spawned. My friend never noticed anything when he was with me. I am using an X1800 with 2GB of RAM and a 3700+ running at 2.5 Ghz. My processor is overclocked but that should effect anything and again my computer runs at very low temperatures. I can run other games such as Far Cry and Oblivion without seeing anything like this. Has anyone else seen this or know a fix for it?

I have an AMD Athlon64 2x processor running at 2.4Ghz with 2Gb RAM and a 512Mb vid card, and I personally didn't get any purple triangles in my several times soloing Linear Train C nor any other graphical glitches anywhere else. Maybe it's with your video card or chipset, I don't know. :

Yeah it is just really odd since it doesn't show any artifacting using ATI Tray Tools and just letting that run for an hour or so. I just want to know if other people with the same video card are getting that glitch. The triangle aren't large and only flash for a second, like artifacts, but they are very distracting since it flashes repeatedly while fighting those enemies.

I get those in some story missions too. Damn distracting, but luckily, it seems a non-crashing type of bug. I also have an ATI card, X1600Pro.

What drivers are you using? I haven't updated for the latest ones yet so maybe that could be part of it.

[SabZero]

Not very new, since I'm on Win2000. 2006 ish

Okay tried to update to the newest drivers. Played the train level again and I still get the glitch.
