Lutris is an Open Source gaming platform for Linux.

This article uses MI Pro (i7-8550U, GTX1050 ti) as an example

Regarding GPU performance: Minimal performance loss (Runs smoother than Windows with only Overwatch installed)

Install Lutris

sudo pacman -S lutris

Install Nvidia Drivers

Prerequisite environment: Bumblebee already installed If you already have Bumblebee installed, there’s no need to disable the service

sudo pacman -S nvidia nvidia-settings

Overwatch is a 32-bit application, so we also need 32-bit Nvidia drivers:

sudo pacman -S lib32-nvidia-utils

Overwatch depends on DXVK:

sudo pacman -S dxvk-bin  # Requires archlinuxcn repo, otherwise install from AUR

Install Nvidia-xrun

sudo pacman -S nvidia-xrun

Configure Nvidia-xrun (Mostly following ArchWiki)

Set nvidia bus id

If /etc/X11/nvidia-xorg.conf.d/30-nvidia.conf already has the bus id configured after installing nvidia-xrun, you can skip this step.

If you installed nvidia-xrun from the [nvidia-xrun github repo], you’ll need to manually set the bus id.

Get the ID: Typically the bus ID is 1:0:0. To confirm, run:

lspci | grep NVIDIA

The ID can be found at the beginning of each output line.

Create /etc/X11/nvidia-xorg.conf.d/30-nvidia.conf with content like:

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
EndSection

Similarly, you can adjust some NVIDIA settings if needed:

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    # Option "AllowEmptyInitialConfiguration" "Yes"
    # Option "UseDisplayDevice" "none"
EndSection

Manage nvidia GPU with bbswitch (Directly following ArchWiki)

Normally use bbswitch to disable the nvidia GPU. When needing to run programs with nvidia, executing nvidia-xrun will activate the nvidia GPU and automatically launch the configured window manager.

• Load bbswitch module at startup

# echo 'bbswitch ' > /etc/modules-load.d/bbswitch.conf

• Options to disable nvidia GPU

# echo 'options bbswitch load_state=0 unload_state=1' > /etc/modprobe.d/bbswitch.conf

Reboot the system to apply.

Check status:

cat /proc/acpi/bbswitch

Toggle GPU using bbswitch commands:

# tee /proc/acpi/bbswitch <<<OFF
# tee /proc/acpi/bbswitch <<<ON

More bbswitch info at Bumblebee-Project/bbswitch

Running KDE with Nvidia

Edit ~/.nvidia-xinitrc and add:

export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json  # Prevents Vulkan loading issues
startkde

After logging into tty, launch KDE desktop environment with NVIDIA rendering using:

nvidia-xrun

Overwatch Left CTRL Key Not Working

Use xmodmap to map left CTRL to right CTRL:

xmodmap -e "keycode 37 = Control_R"  # Only valid for current tty session

The End

Next, log out of current KDE session

Open a new tty and launch KDE with:

nvidia-xrun

Launch Lutris and install Overwatch as usual
