Update: If you're having mouse problems since this update, there's a new Beta to opt into. See here for the details.


A brand new update to Steam Play Proton has arrived ahead of the weekend with Proton 4.11-10, giving out of the box play for Halo: The Master Chief Collection.

For Halo, you will need the Steam Beta Client if you're on an older distribution, plus online matchmaking still won't work due to Easy Anti-Cheat not supporting Steam Play Proton. However, single-player does work fine and you should be able to play with friends outside of matchmaking. I've tested Halo myself, and it does work first time without issues signing into Live:

Also added in this release of Proton is a claim of major mouse handling improvements. They said this improved the experience in Fallout 4, Furi, and Metal Gear Solid V. On the subject of input there's also force feedback improvements, an Xbox controller performance regression was solved, and fixes for multiple games having problems with controller mapping like Telltale games with Xbox controllers and Cuphead and ICEY when using PlayStation 4 controllers over Bluetooth.

There's a new integer scaling mode available, which they said will "give sharp pixels when upscaling". You can enable it with the "WINE_FULLSCREEN_INTEGER_SCALING=1" environment variable.

Apart from that there's a fix for Metal Gear Solid V hanging on launch, Trine 4 should no longer be locked to 30 FPS and a frequent IL-2 Sturmovik crash should be solved. They also updated D9VK, FAudio and pulled in some misc DXVK bugfixes.

See the changelog here. To get the update, your Steam client should download it automatically. If not, ensure you have Proton 4.11 installed in the Tools menu.

Quoting: Schattenspiegelshould you guys not at least wait till they released more then one game of the collection?

My understanding is that buying the collection now will grant access to each game as they come out. Basically a preorder at a discount. This does not apply if you simply buy just Reach.

Quoting: Luke_NukemThis fixes what were some pretty bad FFB faults for steering wheels in a few driving games. link

finally awesome work from berarma and aeikum

A side-note: If you have a G920 wheel, you will need to use kernel 5.4.x plus, or 4.9 and lower. FFB and some other stuff broke around 5.1 series. You will alos need to do a steam --reset after upgrading the kernel..

Ah - so it is a limited time deal then? Then it might actually be wort the gamble, I guess. Just thought that is not really guaranteed that the other entries of the series will actually work with wine/proton so pre-ordering is kind of a risk.

Eeh, looks like I forgot to click "post comment" yesterday. Well, good thing I always install "form history control" on my browsers, here it is (sorry if bits were answered in between) ^^"

Quoting: GuestDoes this update really work well enough with Halo?I'm considering to buy it for a Xmas present... :)

Most people can't play co-op. Achievements seems locked because of EAC (though maybe it works if you launch it with EAC?). Unlocks are disabled as well.

What seems to work quite well is singleplayer, as well as custom multiplayer games.

I'm waiting a bit before buying it myself, to see if the EAC situation could improve, and if they will implement split-screen. I would have bought it already if the MCC pack had been a "complete your collection" bundle.

Tested the new Proton release running the just released Gothic Playable Teaser: it worked like a charm! :)

Unfortunately, 4.11-10 messed up something with Borderlands 2 for me. Whilst Nvidia reported FPS around 120, it kinda looked as if every other frame was being displayed---jumpy, not smooth. Most disconcerting was the way a frame would flash on the screen from an entirely different sequence altogether, like a menu frame while running through Sanctuary or something.

Rolling back to 4.2-9 fixed it right up. Would this sort of regression be best reported to the Proton github page, or should I just assume it'll get fixed up on a later iteration? Or maybe I'll just lock Borderlands 2 to 4.2-9 and call it good.

Never, ever assume a bug will just get fixed. Always report. This could be a d9vk regression.

Integer scaling! Is this for WINE in general or a Proton-only thing?
