- Only one game version tested.
- No AMD AVX2-lacking CPUs (e.g., Phenom II) available—expected similar results.
- Potential legal issues: patching EULA may forbid modification.
Config File (.ini): Allow users to toggle specific instruction emulations to balance stability and performance. uncharted 4 avx2 fix

Step-by-Step Troubleshooting (When the "Fix" fails)
You’ve installed the DLL or set up SDE, but the game still crashes. Here is the checklist: Only one game version tested
Create a Launch Script: Open Notepad. Paste the following:
@echo off
C:\IntelSDE\sde.exe -avx2 -- "C:\Program Files (x86)\Steam\steamapps\common\Uncharted Legacy of Thieves Collection\Uncharted4.exe"
Adjust the path to match your SDE folder and game folder.
Save as: Launch_Uncharted.bat in your game folder.
Run as Administrator: Right-click the .bat file and select “Run as administrator”.
Extract the Files: You will typically find files like com_intel_sde.dll or a modified u4.exe.
When the game tries to call an AVX2 instruction and the CPU doesn't understand it, the application fails silently (or with a generic "Unhandled Exception" error).
