For a short time, this rendered the game unplayable on popular budget CPUs and older Intel/AMD processors (such as some Xeon models, older Core i7/i5/i3, and AMD FX series). Fortunately, a definitive fix was released, rendering complex workarounds unnecessary. The Official Solution: Patch 1.3.20812 (November 2022)

Example A: Game crashes immediately with “illegal instruction” Some users have shared custom file sets (often

Before attempting third-party workarounds, check your game version. Following intense community feedback at launch, the developers released official stability updates. Later patches optimized how the engine handles legacy instruction sets, reducing or eliminating the hard AVX2 requirement for certain hardware configurations. Open your game client ( or Epic Games Store ).

This created a significant problem for players who had capable GPUs like the GTX 1060 or RX 580 and found that their older, but still powerful, CPUs were the sole bottleneck preventing them from enjoying the game. Share public link D
