GE-Proton 10-9 released with NTSYNC and FSR4 upgrade support

GE-Proton 10-9 is out now with some exciting sounding new features like NTSYNC and FSR4 upgrade support for gamers on Linux, SteamOS and Steam Deck.

This is the community-made compatibility layer, not supported by Valve. See my explainer on the different Proton versions and my guide to install GE-Proton for more.

From the changelog:

• Added ntsync support:

Enable with PROTON_USE_NTSYNC=1

NOTES:
1. Your kernel must be patched with ntsync patches. If your system does not have /dev/ntsync then your kernel does not have the patches required to use ntsync.
2. Some applications, mostly 32 bit, may also need PROTON_USE_WOW64=1 when using ntsync

• Added FSR4 upgrade support via PROTON_FSR4_UPGRADE=1 (auto upgrades from amd directly https://download.amd.com/dir/bin/amdxcffx64.dll).
• Added fixes from upstream for flicker/rendering issue when using wine-wayland.
• Refactored a lot of the patches section and cleaned up outdated or merged patches.
• Update wine-wayland patches.
• Updated wine to latest bleeding edge.
• Updated dxvk to latest git.
• Updated vkd3d-proton to latest git.
• Imported all upstream proton changes.
• protonfixes: added a fix for winetricks wget gnutls failing inside fex.
• protonfixes: add fix for sifu freeze (thanks UsernamesAreNotMyThing).

Before getting too excited about NTSYNC though, do note what Valve developer Pierre-Loup Griffais mentioned that I included in the Linux kernel 6.14 release post:

We already include fsync, which should be as fast or faster as ntsync. We developed ntsync as a general solution that'd be acceptable in upstream Wine, but there's no urgency in including it in the Deck / SteamOS kernel.
