This is an okay game. It could use a better SDK and the ability for players to modify already released cars so that they can drive them with different specs from the default, but otherwise, this is an okay racing game. It needs some music, and has some twitchy controls with steering wheels, but supports practically all steering wheels even the driving force GT steering wheel.
-- Content Creation --
If you are like me and into content creation. You can make your own tracks using the Assetto Corsa track, make car retextures, create a custom car based on the Formula K car that Assetto Corsa comes with and more. I've only done the car retextures and gotten tracks that other modders have made. This helps to make this among the best racing games out there in my opinion. Especially since there are a lot of modders out there trying to make content for this game.
-- Steering wheel controller --
Works mostly with the Logitech G27 steering wheel, but the steering wheel's shift indicator doesn't work... (( Look below for solution to this )) It's okay, though kind of takes away from the feel of the game for me. The game with this steering wheel will shift in such a way that allows you to use the manual shifter (H-pattern) when in a car that has an H-pattern shifter, otherwise you're restricted to the paddle shifters for those cars that have that. I prefer the H-Pattern shifter, but there many cars in the game that don't use that shifter.
-- Other issues --
Currently no career mode, and when its added hopefully it won't force people to drive all manner of cars...
Currently some cars are very twitchy if you accelerate oddly quick. This is mostly something from the high horsepower cars.
-- Solutions to problems above --
* Steering wheel issue with G27 and no LEDs use. Download FanaLEDs program, In FanaLEDs program do File - Open Settings, open Global, change revledtype to 1, then save, close FanaLEDs and reopen it. Now you can set up the RPM percentage you want to start counting at, for me this is 60%. And it will count up each LED on the steering wheel until about 500 RPMs before red line and at red line it will start flashing the LEDs to indicate that you need to shift up. I love Assetto Corsa now that this feature works, maybe they will make it so we don't need to use FanaLEDs to get this to work in the future.
*** UPDATE as of Release Candidate 1.0.1 ***
The game's cars don't act like the real world cars anymore. In particular, the production car ones. They feel too twitchy and act more like what you'd expect on an arcade game instead of being something like you'd get on a driving simulator game like GT5. Hopefully, they'll fix this for the actual release.
