Blurry Melbourne track on GTX275

[Wally]

Hi guys, with my Nvidia GTX 275, the white lines on the Melbourne track are horribly smeared and blurry. I have negative LOD bias set to clamp in the nvidia control panel, whcih normally fixes this. Other tracks are generally OK with this, but this track is shocking. Has anybody got any suggestions?

Did you fix this Wally? You could try setting the changed the 'pre-rendered frames ahead' to a higher number (nvidia panel), but it will cost you fps. Could also just be track related.

No fix yet - nothing I changed made any difference, but I didn't try to increase the pre-rendered frames. I'll give it a go - I have plenty of fps to spare. I think you're right about it being track related. I was reading about poor Mip levels on textures on some tracks and so on. Nearly every other track looks fine.
