How to know if my CPU supports AVX or AVX2 instructions?

Some of the high-budget (AAA) games released these days require an AVX (Advanced Vector Extensions) compatible CPU to run on your PC. Such as Sonic Frontiers, Victoria 3, NBA 2K23, Star Citizen, WWE 2K22, Death Stranding, Yakuza 3 Remastered, Age of Empires IV, Dying Light 2, UNCHARTED: Legacy of Thieves Collection (AVX2), etc...

If your CPU doesn't support AVX, when you try to run a game that requires AVX, the game will not launch, and you will see an error message like the one below.

"Your CPU needs to support AVX instructions to run this game."

"Unsupported Hardware Detected. This game requires a CPU supporting the AVX instruction set to run."

"Fatal error. Error launching the application. Please check the system requirements. (AVX)"

"Minimum requirements failed. Warning: Your system is below the minimum requirements. For optimal performance please refer to the supported hardware list. Following CPU instruction sets are required: AVX"

Note: The game may crash even without any error messages.

How to check if CPU supports AVX

Before purchasing a game with AVX requirements, it is wise to check if your CPU supports it.

You can use free software to check this. You can install it by following the steps below. Then use it to make sure that your CPU supports AVX.

HWiNFO Installer
  • Then install it and run HWiNFO64.
  • A tiny window like the one below will appear. Just hit the Run button.
  • When HWiNFO64 is opened, look into the CPU section.
  • If AVX is green, it means your CPU supports it.
  • If you want to play a game on your rig that requires AVX2. You can also see it there. AVX2 is right next to AVX. If it's green, your CPU supports it too.

How Do I See If My Processor Supports AVX or AVX2 via Steam?
