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)
: By using separate executables, users with newer CPUs can still benefit from AVX2 performance gains without being held back by code compatible with older hardware. Other Fixes
The AVX2 remover patch failed to apply correctly, or you are using a different game version. Fix: Verify game files via Steam (Properties > Installed Files > Verify integrity). Re-apply the patch.
Recognizing the issue, developer released an official update on November 16, 2022.
Regardless of the technical nuances, the official patch ultimately resolved the issue for most players. It is worth noting that Intel's SDE emulator was originally , not as a long-term solution for end-users. The fact that it was used extensively by gamers highlights the frustration caused by the artificial hardware lockout. uncharted 4 avx2 fix
Before anything else, ensure your PC meets at least the minimum specs for the game, aside from the CPU:
: Extract the downloaded fix files directly into the game's main directory, overwriting the original files when prompted.
The Uncharted 4 AVX2 Fix: How to Run Legacy of Thieves on Older CPUs
: Newer CPUs continue to use AVX2 for better performance, while older CPUs can now at least run the game, albeit with potentially lower frame rates. Troubleshooting Persistent Issues For a short time, this rendered the game
After the update, players on "legacy" processors have reported the game running at stable framerates (e.g., 40–60 FPS depending on the GPU), whereas it previously wouldn't launch at all. Alternative Workarounds (If Patching Isn't Possible)
Example B: Game crashes on certain areas or after alt-tabbing
Released on GitHub and gaming forums (2023), the fix consists of:
Outdated drivers are a frequent cause of crashes and glitches. Download the latest drivers directly from NVIDIA or AMD. Other Fixes The AVX2 remover patch failed to
Navigate to your Uncharted 4 installation directory and copy the original u4.exe and any existing .dll files to a secure backup folder.
If you are playing an older version or need a manual bypass, several community-driven methods exist:
If you've applied the fix or are using the official patch and still encounter issues, try these general troubleshooting steps that work for many games:
This patch doesn't alter the main game files. Instead, it's an ingenious compatibility layer that works in the background:
Note: Because Intel SDE uses pure software emulation to mimic AVX2 instructions, it introduces massive CPU overhead. This will severely degrade game performance and frame rates.
Create a batch file ( .bat ) to launch uncharted4.exe using SDE. The command usually looks like: sde -- uncharted4.exe .
