OCCT 17.1.3 is available ! Changelog : Gpu3DAdaptive : Fixed : Reverted the Unreal engine upgrade, went back to 5.4 due to critical bugs within the Intel ARC drivers. Fixing this will take time, and might prevent us from using this Engine version. Gpu3DAdaptive : Ported the reliability improvements from the 17.1 branch in this build Enjoy !
