Windows 11 Requirement
Ace Combat 8 officially requires 64-bit Windows 11 on PC. Steam does not list Windows 10, so a Windows 10 system is outside the published minimum specification even if its hardware is otherwise fast enough.
Treat the OS line as a compatibility requirement
The minimum table names Windows 11 rather than “Windows 10 or later.” Until Bandai Namco publishes a broader support statement, Windows 10 compatibility should not be promised.
A machine meeting the CPU and GPU minimums can still fall outside support because of its operating system. Check the OS edition and 64-bit architecture before buying or preloading.
What has not been confirmed
The listing does not explain whether the Windows 11 requirement depends on a specific build, TPM setting, Secure Boot setting or DirectStorage. It also does not confirm Linux, SteamOS or Proton support.
A safe pre-purchase check
Open Windows Settings, choose System and About, then confirm the Windows specification and system type. Also compare the GPU, CPU, memory, DirectX and storage requirements because the OS check alone is not sufficient.
