I run an overclocked 2.4 Northwood 533 at 3.2 with an x1650pro 512mb, 6xAA and 16XAF and my cpu shows consistently 90-100% cpu usage. Would not a dual core or quad core reduce cpu usage and allow graphics card to work to full capabilities?

Thanks for stating the obvious. Top speed fluctuates instead of reaching its max with the speed governor (intake restriction) for variable differential settings.

when using AI to test setups.

Cars do not accelerate to maximum speed regardless of changes in gearing at the differential, at least the FO8 failed to reach terminal velocity.

enough said.

Love the available tracks and cars available with LFS. That being said, if I were to request anything further, I would suggest replicating the tracks from Geogg Crammonds' GP4 with all the subsequent texture updates by Caelean and company. I'm particularly enthralled with the latest edition of the Nurburgring in rFactor, but the 2001 F1 tracks from Crammond's GP4 would be ideal...and they are DX8 compatible.
