iRacing 2023 Season 1 Patch 4 includes improved graphics


The latest iRacing patch has arrived, bringing with it a variety of fixes and improvements for the PC racing simulation. Here’s what’s new in the iRacing 2023 Season 1 Patch 4.

iRacing 2023 Season 1 Patch 4 fixes graphics issues

Compared to other iRacing 2023 Season 1 updates, this is a relatively small patch. Notably, the update fixes a graphical issue. By default, the SpeedTree self-shadow is now disabled.

When this setting was on by default, some players reported stuttering issues as it requires two extra renders of trees. An issue affecting brake glow visual effects is now fixed for a number of cars including the Aston Martin Vantage GT4, Dallara iR-01, Porsche 919 and more.

Additionally, the 2023 Season 1 Patch 4 includes updates and improvements for the NASCAR Next Gen cars and NASCAR Truck Ford F150 along with the Los Angeles Memorial Coliseum, Long Beach Racing Course, and Wild West circuits.

Simulator

Graphics

  • The SpeedTree self-shadow option is now disabled by default for all graphics performance classes. Previously, it had been enabled in all graphics performance classes, but it requires two extra renders of the trees and may have contributed to stuttering or a general performance hit.

Cars

<Car Class> NASCAR Cup Series Next Gen Cars

  • Rub block shapes have been updated.

NASCAR Cup Series Next Gen Ford Mustang

  • Texture mapping on the front fenders has been updated, which fixes issues with damage decals and camera draw distances.

NASCAR Truck Ford F150

  • Fixed an issue with duplicate contingency decals on the nose.

Tracks

Los Angeles Memorial Coliseum

  • Starting grid positions have been moved away from the wall slightly.

Long Beach Street Racing Course

Adjusted the location of the short parade lap grid to give the rear of the field time to get rolling before the green flag is given.

Wild West

Fixed an issue where cars that missed the start would be released immediately and would come out of the pits way ahead of the pack. Now, Race Control properly holds these cars for about 20 seconds so they come out just behind the pack as expected.
