Fix for Linux/Proton users who had their game break after the Iceborne update

[Katten]

As a lot of Linux users who play the game with proton will know the recent Iceborne update broke the games performance down to about 1 to 3 fps.
Over on the Proton github page the community have compiled a fix for Linux users to restore performance to a better level again. Read the github thread here https://github.com/ValveSoftware/Proton/issues/175

The fix has been compiled to a version of proton that can be downloaded here
https://github.com/przmkg/proton-ge-custom/releases/tag/5.0-rc3-GE-1-MHW
Be sure to follow the instructions and read the first thread before installing. This version of proton should only be used with Monster Hunter and it might not be necessary when/if Capcom issues a patch to the game.

Thanks for this. And with the knowledge contained in that thread, I won't be buying any denuvo protected games anymore. There's just too much risk in them breaking and it's only a matter of time before they bring the wineserver to its knees in some other way. And in such scenarios I'm better off getting the game cracked, because at least then I will be able to play it

I probably would've not gotten the game had I known it had denuvo. Wish there was a filter that allowed one to filter out things like denuvo from the steam store. Or at least have some kind of flag next to the game so people know that they are restricted in what they can do with the product the are buying.

It does state on the store page it has 3rd party denuvo protection. But I think this is a first where the copy protection bit me in the ass waaay after buying the product. I mean I have 800 hours in this game and to then I just lose the game to a copy protection update. But yeah, I'm all for the filter! No more temptation to buy a denuvo game just because it gets a sale or something like that.

Thanks dude! Finally able to run Iceborne with this custom proton. Just tested it with Capcom's latest patch. As of Jan 18, 2020, I can confirm this works with Iceborne Ver 10.12.01!

For the others who are trying to make it work on their systems, highly recommend using the link OP mentioned. Instructions found on GloriousEggroll's GitHub: https://github.com/GloriousEggroll/proton-ge-custom <- Refer to the readme.md found at the bottom of the page and look for the "How to install" section

If you want step-by-step instructions:

1. Download the tar.gz OP mentioned: https://github.com/przmkg/proton-ge-custom/releases/tag/5.0-rc3-GE-1-MHW
2. Extract the tar.gz and you should see a folder named "proton-ge-5rc-mhw"
3. Copy the folder "proton-ge-5rc-mhw" to $HOME/.steam/root/compatibilitytools.d/
**** If you cannot see ".steam" on you file manager simply press Ctrl+H to show hidden folders; Note that you have to create the folder "compatibilitytools.d"
4. Open your Steam Client
5. Right click on "Monster Hunter World" in your library
6. Click on Properties
7. Check "Force the use of a specific Steam Play compatibility tool"
8. On the dropdown, select "proton-ge-5rc-mhw" (If you can select this, it's the first indication that your on the right track. Otherwise, check if you've missed anything from the previous steps.)
9. Click on Close to save your settings
10. Restart Steam Client
**** For safe measure/For checking ****
11. Right click on "Monster Hunter World" in your library
12. Click on Properties
13. Go to "Local Files" Tab
14 Click on "Verify Intergrity of Game Files" and wait for it Complete before clicking close
**** For safe measure/For checking ****
15. Play Iceborne!

Of course mad respect to GloriousEggroll, przmkg, and @Guy1524 - Those who made the custom proton fix possible. Thanks bros. You guys rock!

My steam client is not detecting any compatibility tools at all.

Hey dude. Check that the extracted content is in "~/.steam/root/compatibilitytools.d/" and you should have a folder in there named "proton-ge-5rc-mhw". Of course inside it are all the files you extracted from the tar.gz file.

If this is a new system, check if you already have steam play enabled:
https://itsfoss.com/steam-play/

Also check if you already have the drivers required to run Proton/Steam Play at:
https://github.com/ValveSoftware/Proton/wiki/Requirements

Hope this helps bro.

Yes I had the same issue, extracting it in /root/compatibilitytool.d/ worked for me.

Do any of you have the Surveyor Set working?

After setting up the ge patch, the game runs okay-ish (it still has some inconsistent slowdown in the new zone that feels unrelated to the threading issue), but trying to use the Surveyor Set after its initial tutorial causes a blackscreen.

Somebody on Protondb.com was kind enough to link the solution:
https://www.protondb.com/app/582010

To fix surveyor camera do this.

1. Create a folder in your root directory named "_TempPhoto" (sudo mkdir /_TempPhoto)

2 .Give it appropriate permissions (I only tested it with full permissions, sudo chmod 700/_TempPhoto)

3. chown yourusername /_TempPhoto (alternatively you can use: chown $USER:$USER /_TempPhoto)

that is it and it will work with the surveyor on Linux

Thanks a lot, this worked. :)

I have a very specific problem- my game won't launch anymore while using GE's custom Proton (it launches with Valve's own Proton versions, but, y'know, those don't have the performance fixes). It launched the first time so I went in to change my graphics settings, which issued a restart to apply. The game hasn't worked with GE's Proton since then. Any clue to what the problem might be? I've tried:
* Deleting my graphics settings file and starting the game again.
* Validating game files.
* Reinstalling the game.
* Reinstalling GE's custom Proton.

I'm assuming your referring to "graphics_options.ini" and/or "graphics_options_preset.ini"...
Instead of deleting the files, try opening them using any text editor and set the values to lower settings like:

AmbientOcclusion=Off
VolumeRenderingQuality=Off
ShadowQuality=Low

...and so forth. Seems like you tweaked a graphics setting that your GPU does not support. Perhaps try switching:

DirectX12Enable=On

into:

DirectX12Enable=Off

...or vice versa. Hope that helps.
