GloriousEggroll has released a new custom build of their Proton fork based on the latest Proton release.

Proton-5.11-GE-3-MF

This is another stability/quality update, aiming to provide a better gameplay experience and building on top of the previous build.

Fixes:
-Re-enable rawinput (seems staging had it disabled in the previous build)
-Re-enable FakeDLLs and SECCOMP (seems staging had it disabled in the previous build) - needed for Doom Eternal,Detroit:BH, Origin
-Re-enable HideWineExports (seems staging had it disabled in the previous build) - needed for FFXIV
-Fix issue with not being able to regain focus after alt+tab in various games
-Fix issue with GTA V keyboard input not working
-Fix issue with rawinput not working properly within a virtual desktop
-Fix issue with Warframe and SWTOR not rendering correctly in dxvk on nvidia
-Added patch that allows Indiana Jones and the Emperor's Tomb to run
-Added patch that allows MGS: Ground Zeroes to run (keyboard+mouse input is currently broken, needs more work. Works with controller)
-Added workaround for Warframe launcher rendering all black in wined3d mode (game still crashes in wined3d) - Thanks Iglu47
-README has been overhauled. Thank you TheEvilSkeleton!

Again this update is mainly to tackle some of the bigger gameplay related problems and fix some of the issues in the previous two builds.

More notes:
-No additional updates for media foundation, so no changes on that end or any games related to it.
-No updates on EAC. Guy and Blitzcrank are still working on ironing bugs out for that
-No updates on RDR2, Brendan has not made the patches public.
-No, the MK11 desync issue has not been fixed yet and I do not have a time estimate when it will
-No, the MK11 fullscreen hack issue has not been fixed yet, awaiting a rebase from Valve
-Esync and fsync are still disabled and also awaiting a rebase.
