: Modern CPUs still use the standard AVX2 executable to maintain optimal performance, as these instructions help speed up floating-point computations. Manual/Alternative Workarounds
instruction set requirement. This hardware limitation meant that players with older—yet otherwise capable—CPUs like Intel’s Sandy Bridge (i7-2600K) or Ivy Bridge (i7-3770K) were unable to even launch the game. The Official Fix: Version 1.3 November 16, 2022
