GE-Proton 9-21 released for Linux / Steam Deck bringing more game fixes

GE-Proton 9-21 has been released as the community-maintained version of the Proton compatibility layer for running Windows games on Linux Desktop and Steam Deck. Confused on the Proton versions? Check out my up to date beginner's guide.

As a reminder: you should ideally stick with Valve's official Proton on Steam, unless you need specific fixes from GE-Proton. Since it has less testing, and less support, and it's easier to report bugs to Valve if you're using their Proton.

A lot of the changes come from the official Proton like improvements for modding and initial speech synthesis support in Proton Experimental and related projects. Here's all the changes from GE-Proton 9-21:

Upstream:

• imported piper + PROTON_VOICE_FILES changes
• imported misc proton game overrides
• mono updated to 9.3.1
• icu 64 and 32 bit changes imported
• wine updated to latest bleeding edge
• dxvk updated to latest git
• dxvk-nvapi updated to latest upstream commit
• vkd3d-proton updated to latest git
• vkd3d switched from valve version to upstream wine version (same change was made upstream)

Patch:

• Backported wine bug fix patch 56653 for GetLogicalProcessorInformation, fixes edge case crash on some systems for a few games, notably baldurs gate 3 and divinity original sin 2 (thanks mx-moth)

• Add fix for dirt 3 outside of steam (thanks polluxau)
