Ensure your NVIDIA or AMD drivers are fully updated.
CPUs without native AVX2 support are likely to handle the game's high-demand tasks less efficiently. This can lead to lower FPS and stuttering during busy scenes.
Performance hits of 40-60% are common. Uncharted 4 may become a slideshow on a Core i7-2600K. uncharted 4 avx2 fix
AMD introduced AVX2 with the Excavator architecture in 2015 and perfected it with the Ryzen series. Older AMD FX-series chips (like the FX-8350) do not support it.
AVX2 is a set of instructions that allows the CPU to process more data at once, improving performance in demanding applications, including high-end gaming. Uncharted 4 was initially coded to heavily utilize these instructions to manage the complex rendering of Nathan Drake’s final adventure. Ensure your NVIDIA or AMD drivers are fully updated
Some users found that limiting the framerate via the NVIDIA Control Panel—rather than inside the game—prevents crashes, especially for those utilizing the AVX fallback.
When the Uncharted: Legacy of Thieves Collection launched on PC in October 2022, many players with older but still capable CPUs—such as the or Ivy Bridge generations—found they couldn't even launch the game. The culprit was a requirement for AVX2 (Advanced Vector Extensions 2) , a set of CPU instructions that older processors simply didn't have. Performance hits of 40-60% are common
AVX2 extends AVX (2011) by adding:
If you are sitting on a vintage gaming rig—perhaps an overclocked i7-2600K or a salvaged Mac Pro with dual Xeons—you can play Uncharted 4 on PC. It is not a myth.
If you are looking to refine an existing fix, the current gold standard for Naughty Dog PC ports involves the scripts found on GitHub (such as those by Nexus Mods contributors). They often use Cheat Engine scripts to NOP (No-Operation) the checks or use the "Intel SDE" wrapper, though the latter suffers from massive frame-rate drops.
If you own an older CPU and have been wrestling with the "Uncharted 4 AVX2 fix," you have come to the right place. This article explains what AVX2 is, why Naughty Dog used it, and—most importantly—how to actually get the game running on unsupported hardware.
