Valve on Friday announced that it has updated the APU driver for Windows on the handheld PC gaming device, Steam Deck as well as released a couple of other driver updates.


According to Lawrence Yang, a UX designer at Valve, the new APU driver fixes performance issues with Halo Infinite and many other titles that have regressed recently.


Below are the Windows Drivers updates released:

  • APU driver– download here, run setup.exe to install.
    • This driver is updated as of June 16, 2022.
  • Wi-Fi driver– download here, run install.bat to install.
  • Bluetooth driver – download here, run installdriver.cmd to install.
  • SD Card reader driver– download here, run setup.exe to install.
  • Audio drivers
    Download driver 1/2, right-click cs35l41.inf, and select Install. 
  • (last updated June 13, 2022)
  • Download driver 2/2, right-click NAU88L21.inf, and select Install.
  • These INF files will show up as ‘Setup Information’ type files in File Explorer.
  • On Windows 11, right-click and select ‘Show More Options’ to see the ‘Install’ option.
  • Don’t forget to get the updated APU driver above for audio support.

Currently, dual-boot with SteamOS is not available. While Steam Deck is fully capable of dual-boot, the SteamOS installer that provides a dual-boot wizard isn’t ready yet. This will ship alongside SteamOS 3 once it is complete.

Since Steam is not providing ‘Windows on Deck’ support as of now, Windows users are advised to be careful while installing Windows on Steam Deck as it is still causing a lot of problems to the users.

Troubled Windows users took to Twitter to complain about issues such as display driver corruption on Windows, and black screen problem caused by previous APU driver.
