Note that using the filters might result in a slower server list query due to higher data load.
- Server List – trigger request of only immediately accessible servers when appropriate.

When toggling from filtered/sorted full-server list mode to default 100 weighted server list.

- Added backend support for British GT BOP.
NOTE: the British GT season has its own specific BOP for shared tracks (Silverstone, Brands Hatch and Spa) when in single player (only when played through the British GT season in the UI).
In Multiplayer, the shared tracks (Silverstone, Brands Hatch and Spa) always use the GT World Challenge and GT4 European Series BOP.
- Fixed unintended asymmetrical setup presets on various cars.
- BOP-regulated fuel tank limitation implemented in 2020-season Paul Ricard and Spa, values set for all cars.
- Improved vehicle ground collision simulation.
- Improved rev limiter behaviour of the AMR V8 Vantage GT3, AMR V12 Vantage GT3 and Lexus RC F GT3.
- Improved heat generation versus tyre volume, wear, pressure influence for all GT3 and GT4 wet tyres.
Potentially improves the handling of lighter, mid-engined cars in the rain.
Improves the durability of wet tyres in light-moderate wet conditions.
- Fixed front-rear inconsistency in cold wet tyre temperatures on the Audi R8 GT4 and Maserati GT4.

- Improved the influence of ambient conditions on water dissipation in the dynamic track model.
- Fixed an issue with cloud level incorrectly influencing water dissipation during night hours.
- Minor adjustments to the dynamic weather scaling (both single and multiplayer).
Wider cloud variation, lower potential rain deviation from base and lowered maximum weather drift range throughout the weekend.
General notes and guidelines still apply. In MP, variability combined with sessions set on the 3rd day of the weekend still has a chance of notable deviation from base settings.
- Shared memory – added global flags, yellow flags per sector, MFD tyre pressures, fuel to add, tyre set and compound names to shared memory writer.
- Added real-time contact shadows in Visual Options.
Less taxing alternative to using the highest settings for regular dynamic shadows, also helps with shadow pop and undercar shadows when objects leave the shadow cascade.
