| Setting | Recommended Value | Why This Fixes Crashes | | :--- | :--- | :--- | | | Recompiler (LLVM) | Faster loading. Crashing on startup? Try Interpreter (fast) once, then switch back. | | SPU Decoder | Recompiler (ASMJIT) | Critical fix. LLVM for SPU causes random hangs during fights. ASMJIT is slower but stable. | | SPU Block Size | Safe | This is the magic bullet. "Mega" or "Giga" reduces performance but prevents VM: Access violation errors in Title/Entrance scenes. | | SPU Cache | ✔️ Checked | Pre-compiles fight shaders. Reduces mid-fight stutter-crashes by 80%. | | Thread Scheduler | RPCS3 Scheduler (default) | Do not change to "Operating System" – that causes instability here. | ufc undisputed 3 rpcs3 crash fix better
