While it may run, it often results in a "20 FPS slideshow" in intense scenes, though menus might run fine.
Since the game is programmed to look for these specific instructions, there is no simple "On/Off" switch in the settings menu. However, the modding community has created workarounds.
AVX2 Safety and Correctness
Recognising the demand, the developers at eventually released Patch 3 (v1.3) on November 16, 2022. This update: uncharted+4+avx2+fix+free
Software emulation places a massive burden on your CPU. Expect significantly lower frame rates, stuttering, and long loading screens when using Intel SDE. Method 2: Community Made Fixes and Modified EXEs
Uncharted 4 requires a CPU that natively supports AVX2. If you are running an older—yet structurally powerful—processor, the game engine attempts to call an instruction your hardware cannot understand, leading to an instant crash. Affected CPU Generations
The comprehensive guide below addresses the , providing a free and legal method to bypass the CPU limitation that prevents the game from launching on older processors. While it may run, it often results in
While this is often the most convenient fix—sometimes requiring you to simply drag and drop a few modified files into your game folder—you must be highly cautious. Always ensure you are downloading files from reputable, community-vetted forums (like Nexus Mods or trusted GitHub repositories) rather than sketchy "free game fix" websites.
If you encounter issues after installing the bypass, utilize these community-vetted workarounds:
Follow these steps precisely to set up the emulator and get your game running. Step 1: Download Intel SDE AVX2 Safety and Correctness Recognising the demand, the
Phenom series, FX series (Bulldozer/Piledriver like the FX-8350), and older APUs. How to Get the Uncharted 4 AVX2 Fix for Free
Initially, the game would crash on startup for anyone without a CPU from roughly 2013 or later. This was frustrating for many players who had hardware that otherwise met the game's performance needs but simply lacked that specific modern instruction. The Community's Workaround
On a CPU that supports AVX but lacks AVX2 (e.g., Intel Ivy Bridge), the CPUID feature flag for AVX2 (CPUID.07H:EBX[5]) returns 0. When the game executable attempts to execute an AVX2-specific opcode (such as VPBROADCAST , VPMULLD , or 256-bit integer vector operations), the processor fails to decode the instruction. This results in an unhandled exception, crashing the application immediately upon initialization or during asset decompression.
If you are still having trouble launching the game, verify your hardware capabilities:
