This method tricks the Uncharted 4 executable into thinking your CPU supports AVX2. It does this by translating AVX2 instructions into AVX or SSE instructions on-the-fly. There is a slight performance penalty (5-10%), but the game becomes fully playable.

Before we jump into the fix, let’s understand the enemy.

AVX2 (Advanced Vector Extensions 2) is a set of CPU instructions introduced by Intel with the Haswell architecture (4th Gen Core i-series, ~2013) and by AMD with the Ryzen series (2017) . uncharted+4+avx2+fix+free

These instructions allow the processor to perform mathematical operations on large blocks of data (vectors) in a single clock cycle. Game engines use AVX2 for physics calculations, texture decompression, and audio reverb.

The problem? CPUs older than Haswell (like the popular Intel i7-2600, i7-3770, or i5-2500K) do not have AVX2. They have AVX (original) or SSE (Streaming SIMD Extensions).

Sony Interactive Entertainment and Iron Galaxy (the porting studio) compiled the game’s executable with mandatory AVX2 flags. Without hardware support, the game crashes before the logo appears. This method tricks the Uncharted 4 executable into

What to expect:

Are you trying to run Uncharted: Legacy of Thieves Collection on your PC and encountering an immediate crash or an error related to "AVX2"? You aren't alone.

With the recent surge in players grabbing the game (perhaps during a free giveaway or a deep discount), many users are discovering that their hardware isn't quite up to the task—not because of graphics power, but because of specific processor instructions.
