iRacing.com have released a sizable new build for the popular online only racing simulator, containing a host of updated content, new and improved features including DX11 support and the inclusion of four brand new cars from Audi, Mazda, Renault and Mercedes Benz. Perhaps of significant interest to fans of the simulation is the new DirectX 11 beta executable, aimed at improving the rendering processes to reduce CPU bottlenecking and hopefully enhance the fluidity of the gaming experience. It should be noted that both DX9 and DX11 launch options are available and the graphical settings for each version are independently stored within the game. iRacing advise users to note that when setting up any application overrides in your GPU’s device driver’s settings to take care to set them for the correct executable name(s). Also of interest in the latest version of the simulator is the inclusion of a new 'Time of Day' feature that contains options for both morning and late afternoon on all tracks and race modes within the game. Alongside a vast number of changes and fixes to a wide variety of cars within the sim includes the addition of visual dirt/grass/debris pickup on car both player and opponent tyres. Now when a car goes off track and gathers grass or gravel debris the visual dirtying of the tyres is slowly cleaned off as your car circulates the remainder of the race based on surface type, grip and speed of the vehicle. This is a very cool physics based feature that has been available since the previous season build but is now visually represented within the game. With a changelog far too sizable to add to this article, the 2016 season 2 build is sure to be a significant upgrade to the simulation that continues to grow and improve with each new update.
