A small list of fixes has been added to the GT World Challenge sim racing game from Kunos Simulazioni with Assetto Corsa Competizione Hotfix v1.6.4 released for the PC version via Steam.
The update doesn’t include any massive changes, although there are a couple of improvements specifically for the non-eve Ferrari 488 GT3 and 2018 Porsche 991 GT3 R if you regularly drive those cars. But probably the biggest tweak is an improvement to the automatic setup calculation accuracy.

It’s not surprising the hotfix update is pretty small, considering we’ve had four released since the big change to version 1.6.0 and release of the 2020 GTWC Pack DLC on November 18th. And you can check out Assetto Corsa Competizione Hotfix V1.6.1, V.1.6.2 and V1.6.3 if you need to catch up on the tweaks made since then.
Assetto Corsa Competizione Hotfix v1.6.4 Change Notes:
PHYSICS:
- Ferrari 488 GT3 (non-evo) corrected erroneous engine assignment in Paul Ricard 2020 BOP.
- Fixed wrong wet tyre assignment for Porsche 991 GT3 R (2018) in 2020 BOP.
