Since purchasing the Beta this is the only car I have driven - my main use for the original rFactor was the modern F1 mods, so with rFactor2 i decided to focus on the car that was the closest match whilst trying out the new tyre model, physics and FFB.
Yes this car is very twitchy, and by default the setup has a lot of oversteer, but if you can get used to it (and perhaps make some changes to the setup to suit) it becomes a very fun car to drive... and very challenging.
Going through high speed corners the car is always on edge, and you actually find yourself making small corrections with the steering and throttle to keep the car on line - if you're too aggressive you'll be sent into the gravel. I'm not saying this is the first sim to give such a sensation, but it feels real, and when it goes wrong for me i always understand why - that's the sign of a very good physics engine.
Maybe the Formula Renault should have a bit more grip, i'm not sure, but the default setup has quite low wing so people shouldn't really judge the car based on that. It is very difficult to drive at low speed but the engine has a lot of power and the car is very light, so it shouldn't be easy. At high speed it is simply a great challenge - a fun challenge with lots of lateral sideways movement, four-wheel slides and a dangerous change of direction. I love it.
Problems with the Beta?
Well once again I'm having to use Sparse-Grid Super-Sampling in order to smooth out the jaggies, just like every previous ISI based sim. This is really annoying as it cuts the framerate a lot, but if i don't use this setting i have annoyingly jagged painted white lines on the track sides and lots of flickering trackside objects (fences etc).
Circuit texture colours seem very cartoonish and over-bright. Yes i am a bit disappointed in the overall graphical standards here, but the game can actually look very nice at dusk and dawn... unfortunately at midday the colours want to burn my eyes out.
Also the shadow LOD's are truly shocking, especially during the trackside camera replays - no shadows at all under the cars until they get very close to the camera... it just looks awful and ruins what would otherwise be a nice looking sim. Even in the cockpit view i see shadows on the grandstands drawing-in as i'm driving.
Overall though i'm very happy with the Beta as it has had the opposite affect to C.A.R.S.
C.A.R.S. looks stunning, but the physics feel so sluggish that i just can't enjoy driving it - i don't want to drive it. rFactor 2 doesn't look like anything special, but the physics are so good i just want to finish this post and get back behind the wheel again. Of course i know C.A.R.S. isn't even close to Beta stage yet, so it's an unfair comparsion. It's just nice to have something which finally feels like a progression in terms of driving experience.
