rFactor Issues...

I'm not sure how wide an audience we have for this game but there are a few driving enthusiasts floating around on this forum so here goes nothing. I just purchased rFactor online last night after seeing so many screenies of the CTDP F1 2005 mod. The game runs fine provided I don't choose the cars in the CTDP mod. What I'm getting are tyres05.mas errors with gMotor2 spitting out saying that. If I manage to purchase the Minardi car and run it, it renders a box with 4 wheels, literally.

Hope someone knows the problemm first hand and has a solution.

A quick note about the gameplay. Seems like RH05 for F1C and the Sauber F1 game in rFactor are worlds apart. The Sauber gameplay is much more arcadish, imo. I hope it's just the settings I have (TC, etc).

One last question. Does rFactor automatically modulate the graphics according to system specs? It looks like it's running at 800x600 on my 1280x1024 LCD due to my low spec vid card.
