"Silverstone" is one of the many Formula 1 tracks that I have raced over the years on my PC.
For me, it's both one of the best and one of my favorite Formula 1 tracks.
The modders who re-created this track did a great job. Unfortunately, the base/vanilla rFactor game already has this track (it's called "Northamptonshire").
My impressions are that The Silverstone 90s track is almost no different from the North Hamptonshire Track in terms of graphic quality and everything else...
