Uncharted 4 Avx2 Fix Upd -

While the patch allows the game to launch , it is important to manage expectations regarding performance.

Go to your Library and ensure UNCHARTED: Legacy of Thieves Collection has updated to the latest version.

In the custom function, use standard SSE4.2 instructions to mimic the 256-bit AVX2 behavior (this will require two 128-bit operations for every one 256-bit operation). 3. Core Logic Example (C++)

AVX2 allows CPUs to process larger blocks of data simultaneously. Modern game engines use these instructions to optimize heavy calculations. When Uncharted 4 attempts to run an AVX2 command on an unsupported CPU, the processor does not understand the instruction. This causes an unhandled exception, resulting in an instant crash to the desktop without an error message. Share public link uncharted 4 avx2 fix

Uncharted 4 AVX2 Fix: How to Play Legacy of Thieves Collection on Older CPUs

The game builds a massive shader cache upon first launch. If your system instabilities crash the game during this process, it can corrupt the cache. Navigate to your game directory or AppData folder. Locate and delete the psolib or shader cache folder.

thanks to a late 2022 update. This means you no longer need "unofficial fixes" or emulators like Intel SDE to run the game on legacy hardware like Intel Sandy Bridge or Ivy Bridge. The Official Fix: Patch 1.3.20812

This method does not emulate; it simply deletes the CPU check. The game may behave unpredictably (random physics glitches, audio popping) if it tries to use an AVX2 instruction that doesn’t exist. However, it offers native performance. When Uncharted 4 attempts to run an AVX2

In November 2022, a patch was released (v1.3 or Patch 3) that added for older CPUs. This update officially addressed the requirement, allowing the game to run on processors that lacked these specific instructions, though performance on such aged hardware may still be limited. Community Workarounds

Ensure your NVIDIA or AMD drivers are fully updated.
