Bloody awesome mod you've made, the amount of cars is astonishing.
Now I only got a "slight" problem (looked in the thread and the exact same problem hasn't been adressed yet)
First of all my PC specs:
Windows Vista
3GB RAM
Intel Core2 Quad CPU (2.4 GHz)
nVidia 8600GT
I tried running a full-grid race on the VLN 3 Groups track...ok that caused a Run Time error.
I restarted only adding 18 AI's, and then manually add cars using the Add AI button. I got as far as "60" but as soon as I tried to a 61st car, the game crashed.
Tried it again and again and again, didn't work.
So then tried to race with 60 cars (no FPS problems at all) but after 1.5 laps the game crashed..also tried this a couple of times. And trying to proceed to Practice 2 also caused a CTD.
So I'm kinda stuck now.
But don't see this as a negative post! It's a really impressive mod, especially considering it's done by one person. I just hope this might help you to make an even better fix
