sudo pacman -S lib32-nvidia-utils

Configure NVIDIA:

# Open NVIDIA settings
nvidia-settings

# Configure:
# - Performance mode
# - VSync settings
# - Power management

NVIDIA optimizations:

# Enable performance mode
sudo nvidia-smi -pm 1

# Set power limit (if needed)
sudo nvidia-smi -pl 200  # Adjust wattage as needed

AMD Setup

Install AMD drivers:

# AMD open-source drivers (usually pre-installed)
sudo pacman -S mesa vulkan-radeon lib32-mesa lib32-vulkan-radeon

# For newer AMD GPUs
sudo pacman -S mesa vulkan-radeon xf86-video-amdgpu

AMD optimizations:

# Enable performance mode (if available)
# Check with: cat /sys/class/drm/card*/device/power_dpm_force_performance_level

Intel Setup

Intel integrated graphics:

# Install Intel drivers
sudo pacman -S mesa vulkan-intel lib32-mesa lib32-vulkan-intel

Note: Intel integrated graphics have limited gaming performance. Consider a dedicated GPU for serious gaming.

Verify Graphics Setup

Check GPU is working:

# Check NVIDIA
nvidia-smi

What this command does:

nvidia-smi: NVIDIA System Management Interface
Shows detailed information about your NVIDIA GPU
Verifies that NVIDIA drivers are installed and working

What you should see:

A table showing GPU information
Driver version
GPU temperature and usage
Memory usage

If you see an error:

NVIDIA-SMI has failed: Drivers not installed or GPU not active
Solution: Install NVIDIA drivers: sudo chwd -h -a nvidia

# Check OpenGL
glxinfo | grep "OpenGL renderer"

What this command does:

glxinfo: Shows OpenGL graphics information
OpenGL: A graphics API used by many games and applications
| grep "OpenGL renderer": Finds the line showing which GPU is used

Example output (NVIDIA):

OpenGL renderer string: NVIDIA GeForce RTX 3060/PCIe/SSE2

Example output (AMD):

OpenGL renderer string: AMD Radeon RX 6700 XT (radeonsi, navi22, LLVM 15.0.7, DRM 3.49, 6.6.5)

What this tells you:

Which GPU is being used for graphics
If it shows your GPU model, drivers are working
If it shows "llvmpipe" or "software", hardware acceleration isn't working

If command not found:

# Install mesa-utils (contains glxinfo)
sudo pacman -S mesa-utils

# Check Vulkan
vulkaninfo | grep "deviceName"

What this command does:

vulkaninfo: Shows Vulkan graphics API information
Vulkan: A modern graphics API used by many games (alternative to OpenGL)
| grep "deviceName": Finds the GPU name in Vulkan output

Example output:

deviceName     = NVIDIA GeForce RTX 3060

What this tells you:

Your GPU supports Vulkan (good for modern games)
Vulkan drivers are installed correctly
Games using Vulkan will work

If command not found:

# Install vulkan-tools (contains vulkaninfo)
sudo pacman -S vulkan-tools

If you see errors:

Vulkan not supported: Your GPU may not support Vulkan (very old GPUs)
Driver issues: Install/update graphics drivers
Note: Most modern GPUs (2015+) support Vulkan

When to use: If game doesn't use all cores properly
Benefit: Can improve performance on some games

Performance options:

# Disable VSync
-vsync 0 %command%

What this does:

-vsync 0: Disables VSync in the game
VSync: Limits frame rate to monitor refresh rate
Disabling: Allows unlimited frame rate
Benefit: Higher FPS, lower input lag
Trade-off: Possible screen tearing

# Set resolution
-w 1920 -h 1080 %command%

What this does:

-w 1920: Sets width to 1920 pixels
-h 1080: Sets height to 1080 pixels
Result: Game runs at 1920x1080 resolution
When to use: If game doesn't detect correct resolution
Common resolutions: 1920x1080, 2560x1440, 3840x2160

# Fullscreen
-fullscreen %command%

What this does:

-fullscreen: Forces game to run in fullscreen mode
Fullscreen: Game takes up entire screen (no window borders)
Benefit: Better performance, no window manager overhead
Alternative: -windowed for windowed mode

Combining options:

__GL_SYNC_TO_VBLANK=0 -vsync 0 -fullscreen %command%

What this does:
