Compatibility Report

having the same issues here but after changing to dx11 i had no performance cost, on the contrary, had more frames and better stability

I reproduced this on an RX 470. No problem with RDNA1 or RDNA3, so it might be Polaris-specific. I also looked at some RenderDoc captures. It seems like some indexed draws that should normally happen are simply missing, but the draw calls also seem to be reordered every frame, so different geometry goes missing from frame to frame and hence the flickering.

It doesn't happen with RADV_DEBUG=syncshaders or a debug build of vkd3d-proton with breadcrumbs enabled, so it seems like some kind of sync issue. Maybe the game simply expects a faster graphics card?

I have an issue with the in game voice chat. On multiple proton versions (including GE and non GE) The voice chat breaks when joining a party, my mic starts clipping and I have to disable voice chat and re enable it for it to work again. It also breaks when joining a trial.
I'm using pipewire.

1. when you say non ge proton you should specify all versions with which you could get the issue to happen.
2. how often do the mic issues occur? how often does it cut off, how often does break completely? Tried a couple of trials and several group joinings but no issue I could hear or the other person could hear
3. Have you noticed if it only happens when playing with certain people? I played with a pc player, but as I understand there's crossplay, so there's a chance it only happens with certain connections
4. run the game with the following launch parameter PROTON_LOG=1 %command%, this will create a log file on your home folder called steam-1304930.log, if you run into the problem again, upload the log, if it's too big try zipping it first.

1. Any version I tried like proton 9 or hotfix or experimental, they all had this problem.
2. It doesn't break completely, I just keep getting cut off, like a stutter kinda, It starts whenever I enter a trial WITH other players, like during that shuttle sequence. It doesn't happen if I join a trial by myself and I'm the only one there.
3. It happens both with this group I play with and with random pubs.
   EDIT: I should mention that all of the players in my group are on PC and on steam.
4. I will, next time I play.

Microphone input seems to be broken for voice chat in this game too with Proton

(Same symptoms as the reply above, when you go to settings for mic test when alone in lobby, it usually works fine, but when you connect to a game, it will start glitching out and go crazy)

Flairs should be updated as this game is also Steam Deck verified now

For anyone having this issue, I was able to workaround the same (or a very similar) issue by forcing sound=alsa for The Outlast Trials (I used Protontricks for this).

Unfortunately I looked into this and settled on that workaround early last year so I've forgotten many of the details, but I was seeing this spew in my log specifically when joining a 4 player VOIP session:

pipewire-pulse[xxxx]: mod.protocol-pulse: 0xXXXXXXXXXXXX: [The Outlast Trials] overrun recover read:0 avail:1126400 max:15360 skip:1122560

I looked at the source code to the pipewire-pulse module and it looked to me like the issue was related to a hard coded buffer size used in that module for I think pulse sinks.

One thing I do remember is that most recommendations I found on the internet when searching for the above error amounted to "adjust the niceness values of pipewire" and none of those fixed the issue for me. Bypassing the pipewire-pulse module outright was the only workaround I found that solved the issue for me.
