The rapidsharelink doesn't work for me. But in the youtubevideo, on 2.02, did that green mrt have black sheep on it? (i think i spotted myself in the video)
Really 3th place with that little milage? That's good. I can manage to get 5th/6th place if i drive a race without mistakes. Sometimes i come into a slide in a corner and most of the times i can recover from that but what often happens then is that somebody behind me rams into me because i loose speed with the slide and then there is not much recovering left.
I try to race clean, but sometimes i'm out of controll and then everything can happen. But i can't race with a car with only two wheels on the ground and i don't want to spoil other peoples races so i do my best to keep it clean.
I like that track. The faster you come out of that two corners the faster you driver over the straight. Also it helped me finding a balance in the UF1 when braking at (relatively ) high speeds.
In other games you can adjust resolution, details, shadows, viewing distance when your graficscard can't do the job. You can allready change resolution, don't know about the other things but if graphics get fancy i think it's not more then normal you can make them worse to match your pc
For me it still works fine at an XP 2000+, with 750 memory and a Radeon 9500 (@9700)
