How to Fix Uncharted Legacy of Thieves Unsupported CPU?

Why Uncharted Legacy of Thieves is throwing an Unsupported CPU error?

This particular CPU-related error is appearing on your PC while launching the UNCHARTED: Legacy of Thieves Collection game due to the lack of AVX2 instruction set support on the processor that you’re using. If your CPU doesn’t have AVX2 instruction set support then either you’ll have to refund the game to avoid such an issue or you can simply buy a new CPU (even maybe a motherboard) that basically supports the AVX2 instruction set. It’s as simple as that.

However, that’s not the case for everyone, and some of the affected players have found a couple of workarounds helpful enough to resolve the unsupported CPU error on their computer that was occurring while running the UNCHARTED: Legacy of Thieves Collection game on the PC. So, we’ll suggest you follow all the troubleshooting methods one by one until the problem gets fixed. Obviously, there is no harm in trying out the workarounds manually.

1. Check the System Requirements

It’s highly recommended to check out the system requirements properly at your end whether your PC configuration is compatible with the game or not. If your PC specification or the CPU isn’t supported with the respective game then you may encounter startup crashes, black screen issues, graphical glitches, lags, stutters, FPS drops, and so on while trying to launch the game. If your machine lacks any hardware or software compatibility, try upgrading it.

MINIMUM:

  • OS: Windows 10 64-bit
  • Processor: Intel i5-4330, AMD Ryzen 3 1200
  • Memory: 8 GB RAM
  • Graphics: NVIDIA GTX 960 (4 GB), AMD R9 290X (4 GB)
  • DirectX: Version 12
  • Storage: 126 GB available space

RECOMMENDED:

  • OS: Windows 10 64-bit
  • Processor: Intel i7-4770, AMD Ryzen 5 1500X
  • Memory: 16 GB RAM
  • Graphics: NVIDIA GTX 1060 (6 GB), AMD RX 570 (4 GB)
  • DirectX: Version 12
  • Storage: 126 GB available space

As you can see that you’ll at least require an Intel i5-4330 or AMD Ryzen 3 1200 CPU on your desktop/laptop to be able to run this game. That means you have to use 4th generation processor at least or higher generation to make it compatible. If you’re using any CPU with third-gen or before, the game might not run.

Additionally, we’ve already mentioned above that your CPU will have the AVX2 instruction set support to run the UNCHARTED: Legacy of Thieves Collection game on the computer. There is no way or shortcut to get rid of this issue right now. If your CPU doesn’t support the AVX2 instruction set then make sure to buy a new CPU that supports it. You can check out some of the CPUs below that support the AVX2 instruction set officially (out of the box).
