sadly changing the FSB back to normal didn't solve or reduce it, Descent sadly has the same issue, the AGP version didn't suffer from that.

the only odd part about this PC (other than the V3+GF2 setup) is that Im using a 700Mhz Coppermine in an Abit BX6 rev1 motherboard that officially only supports a 600Mhz Katmai, though I can't imagine that causing the issue

another game that does this is Beneath a Steel Sky, on this one, the flicker is on the right side of the screen.

Absolutely gorgeous build!
