Steam Deck’s latest Windows driver update fixes performance issues


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

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

Below are the updates for Windows drivers that have been released:

  • APU Driver– download here, run setup.exe to install.
    • This driver has been 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 on cs35l41.inf and select Install.
  • (last updated June 13, 2022)
  • Download driver 2/2, right click on NAU88L21.inf and select Install.
  • These INF files are displayed as ‘Setup Information’ files in File Explorer.
  • In Windows 11, right click and select ‘Show more options’ to see the ‘Install’ option.
  • Don’t forget to download the updated APU driver above for audio support.

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

Since Steam does not offer ‘Windows on Deck’ support at this time, Windows users are advised to be careful when installing Windows on Steam Deck as it still causes many problems for the users.

Concerned Windows users took to Twitter to complain about issues such as display driver corruption on Windows and a black screen issue caused by a previous APU driver.
