Hunt Showdown 1896 HDR on linux

Here I will show you how to get huntshowdown functioning properly with HDR and the Steam Overlay using Gamescope.
First we will enable the steam compatibility to proton experimental and ensure experimental is on on lastest/bleeding edge.
Then we will install gamescope using yay in the terminal using the command:
yay -S gamescope-git
After that we will insert launch commands into the game properties via steam.
The launch commands we will be using I will list;
gamescope -W 2560 -H 1440 -r 240 --hdr-enabled -f --force-grab-cursor %command%
A break down of what each of these does,
gamescope launches gamescope
-W sets the width of pixels if you want a different resolution use different pixel counts 1080p is -W 1920 -H 1080 UHD/4K -W 3840 - H 2160
-H sets the height of pixels
-r sets the refresh rate for the window. I recommend not exceeding your monitors refresh rate, but you can set this to any number. I use 240 here because that is my monitors max FPS/HZ.
--hdr-enabled enables hdr
-f forces full screen when launching
--force-grab-cursor forces the cursor to stick in the game window. Useful if you sometimes have your cursor leave the game window and click somewhere out of the game causing your system to lose focus on the game. Good for dual monitors, or if you have weirdness with the mouse like sensitivity is way too high or low.
%command% targets the game executable with these launch options.
I personally use Arch Linux with KDE Plasma as the desktop environment.
