Here is another small follow-up to our 2016 Season 1 Release. We’ve fixed a few more issues, and added in a few more balance tweaks.
SIM
– Fixed an issue that reduced the maximum number of car positions transmitted to you by the server, causing fewer than the actual number of cars to be displayed.
Rendering
– Improved the Level of Detail selection of the track surfaces for very wide fields-of-view in three-screen mode. Previously, the side monitors could render distant portions of the track at a higher level of detail than necessary.
– Added the ability to limit the number of track surface decals rendered from the cockpit cameras. These limits can be specified in the โrenderer.iniโ file. The โMaxTrackDecalsInCockpitโ setting is for the driverโs view, and the โMaxTrackDecalsInMirrorsโ setting is for the driverโs view in the mirrors. Because track surface decals are rendered in clumps, try adjusting the settings using increments of about 150. If any portion of a clump would render, the entire clump will render, so the limit input may be slightly exceeded. All decals very near the camera will render even if the limit is exceeded to avoid very obvious popping in of the decals. Mirrors will only render track decals when the โHigher Detail Mirrorsโ setting is enabled in the Graphics/Replay options screen, which will negatively affect performance.
Opponent Cars
– Fixed an issue where the tires of opponent cars would wobble, causing smoke.
Telemetry
– Several values have been added for better monitoring of the McLaren MP4-30, including: ERS Battery Charge, Power from Battery to MGU-K, and Power from MGU-K to Battery.
McLaren MP4-12C GT3
– Fixed an issue where a second steering wheel could be seen in the external model.
NASCAR Sprint Cup Chevrolet SS
– Extra gear options have been added for this vehicle at Atlanta Motor Speedway due to the rev limiter.
NASCAR Sprint Cup Ford Fusion
– Extra gear options have been added for this vehicle at Atlanta Motor Speedway due to the rev limiter.
NASCAR Sprint Cup Toyota Camry
– Extra gear options have been added for this vehicle at Atlanta Motor Speedway due to the rev limiter.
Star Mazda
– Downforce has been increased in response to feedback from a real-world driver.
– Diff locking has been reduced from 10% to 3%.
– Tire grip has been increased slightly.
