GE-Proton brings DirectX 12 fixes for Steam Deck and Linux desktop

By - | Views: 27,049

Another release of GE-Proton is already available, the third in the space of a week and GE-Proton 7-46 includes some DirectX 12 fixes for Steam Deck and Linux desktop. The previous release also removed DXVK-Async, a popular patch people were using to improve the shader cache stuttering issue.

For GE-Proton 7-46 here's the games that had their DirectX 12 mode fixed:

  • Warhammer 40,000: Darktide.
  • Death Stranding.
  • The Division 2.

But it's noted that Monster Hunter Rise is still problematic.

Here's a video going over how to install and use it, a run over the patch notes with an example of The Division 2 DX12 mode now working and some settings to pick for it:

Text Guide to install GE-Proton:

  • Download
    • Desktop: head to the official website, scroll down and pick your favourite download option either AppImage or Flathub.
    • Steam Deck: simply download ProtonUp-Qt from Discover in Desktop Mode (Steam Button -> Power - Switch to Desktop).
  • Load ProtonUp-Qt.
  • Make sure it's set to Steam at the top and select to install GE-Proton.
  • Reload Steam to update the compatibility layer list.
  • In Steam:
    • Desktop: right click a game and go to Properties.
    • Steam Deck: find the game in your library, go to the little COG on the right and then select Properties.
  • Compatibility menu -> Tick the box, select GE-Proton from the drop-down

Update: the article originally noted (as in the video) that God of War was included but it was an error in the GE-Proton changelog as it’s DX11.

The performance on my rig(r7 5700x, 6700xt, 16gb ddr4 on Lutris) it's sucks!!! I hope with this new Proton release works better than now.
Cheers to Kurumin ! It was also my first distro of choice in the linux world.

I'm yet to try again, but last time I played on my Linux Mint 20 I had performance issues. Turns out that Radeon driver didn't ramp up the GFX when needed. I found a manual script to do it for me; otherwise it stayed at idle clocks and it's pretty much 50% off of the performance.

Now only if any of these systems actually recognized & worked easily, for I know I am quite adept with linux and still I struggled to figure out what's the cause and even more so as to how to fix it.

I don't think that it's a GPU Drivers problem, actually I can play Horizon Zero Dawn (and others) in Ultra setting. The Division 2 it's look not to be optimized as it should, we need wait for some patch. Even some Windows users have some problems with this game.
