Assetto corsa update 1.2 + bonus pack available!

The new build 1.2 of Assetto Corsa is available for all users on Steam, at the URL
http://store.steampowered.com/app/244210/.

The new version provides a considerable update and adds five new cars and one circuit as free bonus content. The free bonus pack does not introduce only new content but, more importantly, new features and sensible improvements, in all sectors: artificial intelligence, physics, multiplayer features, graphics and general performance.
The changelog lists all the updates, fixes and modifications applied to the new build of Assetto Corsa, that now is even more stable, and includes new physics algorithms regarding the tyre model, force feedback and artificial intelligence.
Here is a description of the main areas of fixes, content and features included in the Assetto Corsa v.1.2 update:

General
The updates related to the physics engine and force feedback allows to appreciate even more the new cars included in the bonus pack and rediscover the old ones, since all the previous and existing content available in Assetto Corsa have been updated to take advantage of the latest improvements. Some graphics glitches known since the 1.0 version have been fixed: motion blur feature now works properly on any circuit, tyres “glued” to the road in multiplayer have been corrected, and two new features have been added for the driving view: now the dedicated app allows to find automatically the proper eye position, showing also a visual indication for suggested eyes position and actual eye position for Driver Eyes, in order to help gamers to find the correct match, if they desire to set it manually. All content has been updated in order to set a better driving view position with any car. Also, the limits from Driver Eyes Positioning app have been removed, in order to allow players with dedicated rigs or cockpits, free to set their prefered driving view. A huge operation of fine-tuning has involved all the car values, including lods, instrumentation, 2D/3D details, skins, and so on. Furthermore, continuing the general process of improvement, the game now features glowing brakes for high performance and racing cars.

Physics
Differential were updated with the latest electronic wizardry in order to simulate the intricate torque vectoring system at the base of the Nissan GTR incredible handling. Tyre model was also improved by refining the pneumatic trail math model to generate a more self aligning torque, together with improved relaxation length model it will now feature a much smoother ride and more consistent steer feedback.

Artificial intelligence
Artificial Intelligence is sensibly improved both by making it closer to humans performance in corner exit and in general race craft during the race; AI is now able to choose the proper tyre compound for a given session, better handle turbo strategy during qualify and race, improved DRS usage. Driving lines have been improved, as well as the ability of AI drivers to overtake each other and the player. Now they are more aggressive, and they take advantage of any mistake to take your position.

Multiplayer
The update of multiplayer is the result of the feedback received by the community, that asked for more stability and better tools for a more consistent multiplayer experience and leagues organization.
Amongst the various bug fixes included in this update, like the corrected checksum for circuits that use the new configuration system, better collision samples triggering, tyres that properly jump together with the car and so on, we also get some brand new and highly requested features.

We now offer you the possibility to limit the tyre choice, weather settings on the server side, lock of new players joining races, complete last lap in qualify and practice, add ballast for players and much more. Even more importantly a new complete server side UDP plugin for real time data input/output has been implemented. This particular feature will be of great help to all the league organizers and could bring very important developments in AC multiplayer in the near future.

New content
Regarding the selection of the new cars, the Alfa Romeo Mito Quadrifoglio Verde joins the fight versus the 500 Abarth EsseEsse and can also teach a thing or two against some older RWD machinery; the Audi Quattro is a legendary car so loved by car enthusiasts. The Audi had over 300bhp and 4 wheel drive in the mid 80s. A tuned step1 version with locked differentials and more power has been added to satisfy the hardcore car enthusiasts! The Lamborghini Miura SV is the first Lamborghini model officially added in Assetto Corsa. It defined the term supercar back in the 60s and now we give you the opportunity to drive this million value piece of car history. The Toyota GT86 is a very balanced car, and for this reason, maybe is one of the most wanted model included in the new package. This car has been developed in
cooperation with RSR Nurburg, that knows each single secret of this modern hachi-roku (eighty six), a car that makes every car enthusiast yell with excitement and every tyre tremble with fear. The Nissan GT-R Nismo introduces in Assetto Corsa the active central differential and it's the second 4WD car now available after the Alfa Romeo 155 DTM.

The Circuit of Zandvoort, a well-known motorsport race track located in the dunes north of Zandvoort, Netherlands, is the latest addition of the new build: the circuit gained popularity because of its fast, sweeping corners such as Scheivlak as well as the "Tarzanbocht" (Tarzan corner) hairpin at the end of the start/finish straight. Tarzanbocht is the most famous corner in the circuit. Since there is a camber in the corner, it provides excellent overtaking opportunities. It is possible to pass around the outside as well as the easier inside lane.
