Build 1.4.5 of Automobilista has been released, introducing Stock Car Brazil 2017, Curvello and a whole host of new fixes... Now coming with some dramatic improvements to the artificial intelligence as they react with the other computer generated cars and player, plus a rule update to match the 2017 Stock Car Brazil regulations, the new update adds plenty of interesting changes to the core game code. Alongside updates and fixes, new content in the form of the 2017 Stock Car Brazil season and the Curvello track are added to the sim for free. Check out the trailer and changelog below: CONTENT Added Curvelo circuit ("A" & "B" layouts) Added Stock Car Brasil 2017 series UPDATES & FIXES Revised AI overtaking risk calculations - AI now constantly looks for a way past a slower car ahead (no longer backs off overtakes) * Revised & Expanded Push-to-Pass functionality, simulating Stock Car 2017 season (including windshield lights indicating activation / availability) AI now also uses P2P to overtake / defend from opponents Added new car-specific AI risk calculation parameters for overtaking - AI now factors corner radius ahead to decide whether to try switch lines to overtake Added new AI function to prevent AI car from trying to rejoin the track after a spin until there is no oncoming traffic AI now affected by grass / gravel grip levels & dirt on tires (it will lift a bit until tires are clean again) Added new controller damping sliders & presets for better keyboard & gamepad control ** Moved camera settings to DISPLAY UI screen, & added a "Lock to Horizon" slider (where 0% is pre-v1.4 setting, and 100% is latest setting) Added Garage UI warning message for series in which race refuelling is not allowed, & disabled HUD pit menu fuel adjustment for those series *** Several minor UI fixes & adjustments Adjusted audio occlusion, low pass & wind filters Adjusted AI drafting, slip reaction, aggression levels Changed default cockpit FOV from 50 to 45 degrees Adjusted traction control functionality (as a driving aid) Added PLR file setting to disable track scoreboards (known to cause some issues in live streaming) Track state regression between sessions & overnight reduced from 2% & 10% respectively to 1% & 5% Corrected excessive fuel consumption in Caterhams, MCR, Marcas, Lancers Updated sunrise/sunset lighting values for all tracks Updated Cadwell, Brands, Imola, VIR, Curitiba. Cascavel, Kansai, Velocittá, Taruma, Goiania, Spielberg, Santa Cruz, Guaporé, Londrina, Interlagos terrain & road textures to latest quality standard Minor road & curb updates at Curitiba, Tarumã, Goiania, Santa Cruz, Londrina, Interlagos to match their 2017 layouts Fixed F-Ultimate tire options for Interlagos, Kansai Karts: Fixed handling-breaking suspension bug from last hotfix MCR: Fixed RPM LEDs not working in left-hand driver side Camaro: Added 2017 Stock Car Safety Car skin * For this build Medium aggression is generally recommended for best AI racing; higher settings may be suitable for tin tops in which more bumping & rubbing is acceptable; Low aggression disables all new risk bypassing functions and effectively reverts to their pre v1.4.5 behavior with regards to overtaking. ** Users of digital inputs should review their settings for steering, throttle and brake rates. *** All cars / tracks still allows race refuelling for all classes, so users looking to get around series refuelling rules should use that for both single & multiplayer races (be advised that AI fuel strategy for longer races may not be ideal). Important note for Logitech G29 / G920 users: Support for auto rotation is still on a dedicated Beta Branch labeled v1.4.5_G29. Further instructions as to how to switch to a beta branch here. GENERAL NOTES: If you have an online race tonight, you may stick to or revert to the previous v1.4.32 by selecting that branch from the Steam Beta tab. Further instructions as to how to do that here.
