NorthstarProton

A Proton build based on GloriousEggroll's proton-ge-custom that serves as an official, stable, and supported runner for playing Titanfall 2 + Northstar on Linux and SteamDeck.

IMPORTANT

• This is a custom build of Proton, and is not affiliated with Valve's Proton.
• The use of this Proton build, or any Proton build, outside of Steam is universally unsupported.
• Report any issues with this Proton build to this repo -OR- make a ticket on the Northstar Discord invite link. Do not take them to upstream wine, Valve, or GE.
• Do not use this Proton runner for any games other than TF|2 / Northstar

What's new (vs. legacy NorthstarProton)

• Valve wine base instead of wine-staging
• Soft fork of proton-ge-custom instead of using Proton-TKG build system
• No longer requires a minimum system glibc version
• Support for SRMM

LatencyFleX

Once you have installed the vulkan layer properly, LatencyFlex can be enabled by adding LFX=1 %command% to your Titanfall 2 launch options, nothing else is required.

Building

1. Clone this repo by executing:

git clone --recurse-submodules https://github.com/R2NorthstarTools/NorthstarProton

2. Drop any custom patches into patches/, then open patches/protonprep-valve-staging.sh and add a patch line for them under #WINE CUSTOM PATCHES in the same way the others are done.

3. Apply all of the patches in patches/ by running:

./patches/protonprep-valve-staging.sh &> patchlog.txt

in the main NorthstarProton directory. Open patchlog.txt and search for "fail" to make sure no patch failures occured. An easy way to do this is like so:

grep -i fail patchlog.txt
grep -i error patchlog.txt 

4. Navigate to the parent directory containing the NorthstarProton folder.

5. Type the following (note: if using docker instead of podman, change to --container-engine=docker):

mkdir build && cd build
../configure.sh --enable-ccache --build-name=SOME-BUILD-NAME-HERE --container-engine=podman
make redist &> log

Build will be placed within the build directory as SOME-BUILD-NAME-HERE.tar.gz.
