Uncharted: Legacy of Thieves Collection
Playing Uncharted: Legacy of Thieves on Older CPUs If you’ve been trying to run on an older PC, you likely hit a wall: the AVX2 instruction set requirement . Without it, the game simply wouldn't launch. However, a major official update has changed that, making the game accessible to many more players. The Official Fix: Patch 1.3.20812
9. Conclusion
- Uncharted 4 is a AAA action-adventure game with heavy CPU and SIMD usage for physics, animation, and AI.
- AVX2 provides 256-bit SIMD, doubling vector width vs. SSE and enabling higher throughput, but requires careful alignment, register management, and handling of denormals/FP state.
- Common problems migrating code to AVX2: unaligned loads/stores, mixing AVX and SSE without VZEROUPPER, clobbered XMM registers, and assumptions about register width in assembly intrinsics.
- Memory freeing bugs in games often stem from use-after-free, double-free, mismatched alloc/free APIs, or freeing memory still referenced by asynchronous GPU/physics tasks.
