### Install Game Mode for CPU Governor Optimization

Source: https://github.com/lutris/docs/blob/master/Performance-Tweaks.md

Game Mode optimizes CPU governor to 'max performance' during gameplay, potentially improving FPS. Ensure 'gamemode' and 'lib32-gamemode' are installed and your system supports multiarch/multilib. Requires Lutris 0.4.23 or higher.

### Generating Lutris Debug Information (Bash)

Source: https://context7.com/lutris/docs/llms.txt

Provides commands to gather debugging information for Lutris, including submitting a system report, running Lutris in debug mode, and accessing game-specific logs. This is crucial for troubleshooting.

```bash
# Generate system information report
lutris --submit-issue

# Run Lutris in debug mode
# Kill existing Lutris process first
killall lutris

# Start Lutris with debug output
lutris -d
# Reproduce the issue
# Copy terminal output to https://paste.ubuntu.com

# Get game-specific logs
# 1. Launch game in Lutris
# 2. Reproduce issue
# 3. Click log button in right sidebar
# 4. Upload log content to https://paste.ubuntu.com

# Enable Wine debug output for Wine games
# Right-click game > Configure > Runner options
# Check "Output debugging info"
# Re-run game to generate complete Wine logs
```

--------------------------------

### Run Lutris with Debug Logging Enabled

Source: https://github.com/lutris/docs/blob/master/ProvidingLogs&SystemInfo.md

To capture detailed debugging output from Lutris, run the application with the `-d` flag from a terminal. This is crucial for identifying the root cause of problems. Ensure Lutris is not running before executing this command.

```bash
lutris -d
```

### Set vblank_mode for Nvidia Input Lag Reduction - Shell

Source: https://github.com/lutris/docs/blob/master/Overwatch.md

This command adds an environment variable `vblank_mode` with a value of `0` to system options. This is a common technique to reduce input lag on Nvidia graphics cards by disabling vertical synchronization.

```shell
vblank_mode=0
```

--------------------------------

### NVIDIA Environment Variables for Game Optimization

Source: https://github.com/lutris/docs/blob/master/Performance-Tweaks.md

Set environment variables per game in Lutris to optimize NVIDIA GPU performance. Latest drivers are recommended. Be cautious of potential freezes with high FPS and enabled flipping without V-Sync.

```bash
Environment variables can be set per game in Configure > System Options > Environment variables.
```

--------------------------------

### Verifying Trace File Quality (Bash)

Source: https://context7.com/lutris/docs/llms.txt

Checks the size and integrity of a generated game trace file using 'ls -lh'. Valid traces are typically large (hundreds of MB to several GB), while small files indicate insufficient data capture.

```bash
ls -lh program.exe.trace
```

--------------------------------

### Configure Esync for Improved Game Performance

Source: https://context7.com/lutris/docs/llms.txt

Enables Esync to reduce synchronization overhead for better multithreaded game performance on Linux. This involves modifying system limits for open file descriptors, applicable to systemd-based and pam-limits systems.

```bash
# Check if system is esync compatible
ulimit -Hn
# Should return 524288 or higher

# Method 1: Configure systemd (Ubuntu and systemd-based systems)
# Edit with root privileges: /etc/systemd/system.conf and /etc/systemd/user.conf
# Add or modify:
DefaultLimitNOFILE=524288

# Uncomment the line if it exists (remove leading #)
# Restart computer after changes
sudo reboot

# Verify the change took effect
ulimit -Hn

# Method 2: Configure pam-limits (Arch, Fedora, Solus)
# Edit /etc/security/limits.conf with root privileges
# Add (replace 'username' with your actual username):
username hard nofile 524288

# Restart computer and verify
sudo reboot
ulimit -Hn

# Esync is automatically enabled in Lutris 0.5.9+ with compatible Wine versions
# To disable esync for a specific game:
# Right-click game > Configure > Runner options > Disable Esync
```

### Configure DXVK_HUD for Frametime Monitoring

Source: https://github.com/lutris/docs/blob/master/Performance-Tweaks.md

Set the DXVK_HUD environment variable to 'frametimes' to visualize frametime performance. This helps in adjusting in-game settings like V-Sync and FPS limit for smoother gameplay. Works with games running via DXVK.

```bash
DXVK_HUD=frametimes
```

--------------------------------

### Manage NVIDIA Shader Cache

Source: https://github.com/lutris/docs/blob/master/Performance-Tweaks.md

Optimize shader loading performance on NVIDIA GPUs by managing the shader cache. Use `GL_SHADER_DISK_CACHE` to enable/disable and `GL_SHADER_DISK_CACHE_PATH` to set a per-game cache location. The default cache size is 128MB.

```bash
GL_SHADER_DISK_CACHE=0
```

```bash
GL_SHADER_DISK_CACHE=1
```

```bash
GL_SHADER_DISK_CACHE_PATH=/path/to/location
```

--------------------------------

### Disable Network Access for Games

Source: https://context7.com/lutris/docs/llms.txt

Provides methods to block network connectivity for games while maintaining local functionality. Options include using 'flatpak-spawn --no-network' for Flatpak applications, configuring OpenSnitch firewall rules, or using Firejail with '--net=none' for native packages.

```bash
# Method 1: Flatpak (Flatpak package only)
# Right-click game > Configure > System options > Command prefix
flatpak-spawn --no-network

# Method 2: Firewall using OpenSnitch (All packages)
# Install OpenSnitch
sudo pacman -S opensnitch  # Arch
sudo apt install opensnitch  # Ubuntu

# Configure OpenSnitch rule:
# 1. Action: Reject
# 2. Checkbox: From this executable
# 3. Path: /path/to/wine/runner (e.g., ~/.local/share/lutris/runners/wine/ge-proton)
# 4. Duration: Always
# 5. Save

# Method 3: Firejail (Native package only)
# Install firejail
sudo pacman -S firejail  # Arch
sudo apt install firejail  # Ubuntu

# Add as command prefix in game configuration
firejail --noprofile --net=none
```

--------------------------------

### Disable Network for Native Games with Firejail

Source: https://github.com/lutris/docs/blob/master/DisableNetworkAccess.md

This approach is suitable for native Lutris packages. It utilizes Firejail, a security sandbox, to restrict network access. The command `firejail --noprofile --net=none` is added as a command prefix in Lutris game settings to enforce network isolation.

```bash
firejail --noprofile --net=none
```

--------------------------------

### Control NVIDIA Threaded Optimization

Source: https://github.com/lutris/docs/blob/master/Performance-Tweaks.md

Control NVIDIA's threaded optimization using the `__GL_THREADED_OPTIMIZATION` environment variable. Set to '1' to force enable, '0' to disable. Note: This has no effect on Vulkan games and may lower FPS if the CPU is maxed out.

```bash
__GL_THREADED_OPTIMIZATION=1
```

```bash
__GL_THREADED_OPTIMIZATION=0
```
