So finally got the beta and have to say I'm pleasantly surprised by what I've seen and felt so far. The Megane is a fun car to drive, while the Formula Renault is a bit meh. The 1960 F1 car is something that needs a bit more practice in before I can fully commit to it.
The Tyre Model seems to be similar to netKar Pro in that when you get understeer going on you can 'feel' the front tires wash out and scrub. There grip line seems to work well and running through the gravel (as I often do) creates problems down the line
The only criticism I can aim at it so far is that the AI seem a bit scripted (lock wheel then bizarre spin) and that it's a hog on the CPU at the moment as such my PC which meets the min spec easily, suffers some FPS lag when it gets busy in a race.
Overall though, good fun, and that what I look for in a game.
