This guide helps you diagnose and resolve common issues when using Ryujinx. Follow these troubleshooting steps to get your games running smoothly.

​
System Requirements

Before troubleshooting, verify your system meets the minimum requirements:

RAM

Minimum: 8GBInsufficient RAM is a common cause of crashes and poor performance.

Graphics

OpenGL 4.5+ or Vulkan 1.2+Update graphics drivers to the latest version.

CPU

64-bit CPUModern multi-core CPU recommended for best performance.

Operating System

Windows 10/11, Linux, or macOSKeep your OS updated to the latest version.

​
Log Files

Log files are essential for diagnosing issues:

​
Locating Log Files

Default Location:
%APPDATA%\Ryujinx\Logs\
Or from Ryujinx executable directory:
<RyujinxInstallDir>\Logs\
Quick Access:
  1. Press Win + R
  2. Type %APPDATA%\Ryujinx\Logs
  3. Press Enter

​
Enabling Detailed Logging

For better diagnostics, enable additional logging:
1

Open Logging Settings

Navigate to File > Settings > Logging
2

Enable Log Levels

Enable these log levels:
"LoggingEnableDebug": true,
"LoggingEnableStub": true,
"LoggingEnableInfo": true,
"LoggingEnableWarn": true,
"LoggingEnableError": true
Trace logging provides even more detail but impacts performance:
"LoggingEnableTrace": true
3

Enable File Logging

Ensure file logging is enabled:
"LoggingEnableFileLog": true
4

Reproduce the Issue

  • Save settings and restart Ryujinx
  • Reproduce the problem
  • Check the latest log file for error messages

​
Reading Log Files

Log files are named by timestamp: 
Ryujinx_2026_03_10_14_30_25.log
Look for lines containing:
  • ERROR - Critical errors
  • WARN - Warnings that may indicate issues
  • STUB - Unimplemented features being used

​
Common Issues

​
Startup and Installation Issues

Solutions:
  1. Check for missing dependencies:
    • Windows: Install .NET 8.0 Runtime
    • Linux: Install .NET 8.0 via package manager
    • macOS: .NET is bundled with Ryujinx
  2. Verify system requirements:
    • 64-bit operating system
    • Minimum 8GB RAM
    • OpenGL 4.5+ or Vulkan 1.2+ support
  3. Run as administrator (Windows):
    • Right-click Ryujinx.exe
    • Select “Run as administrator”
  4. Check antivirus/firewall:
    • Add Ryujinx to antivirus exceptions
    • Temporarily disable to test
  5. Delete configuration and restart:
    • Backup and delete Config.json
    • Ryujinx will create a new default config
  6. Check logs for specific errors:
    • Look in Logs folder for recent log files
    • Search for ERROR or EXCEPTION messages
Causes:
  • Outdated graphics drivers
  • Unsupported graphics backend
  • GPU doesn’t meet requirements
Solutions:
  1. Update graphics drivers:
    • NVIDIA: GeForce Experience or nvidia.com
    • AMD: Radeon Software or amd.com
    • Intel: Intel Driver & Support Assistant
  2. Try different graphics backend:
    • Edit Config.json
    • Change "GraphicsBackend" from "Vulkan" to "OpenGl" (or vice versa)
    • Restart Ryujinx
  3. Verify GPU capabilities:
    • Windows: Run dxdiag and check GPU
    • Linux: Run glxinfo | grep OpenGL or vulkaninfo
    • macOS: About This Mac > Graphics
  4. On multi-GPU systems:
    • Force Ryujinx to use dedicated GPU
    • Windows: Graphics Settings > Add Ryujinx > High Performance

​
Game-Specific Issues

Diagnostic steps:
  1. Verify game file integrity:
    • Check if file is complete and not corrupted
    • Try loading a different game to test emulator
  2. Check firmware and keys:
    • Ensure latest firmware is installed
    • Verify prod.keys is present and valid
  3. Enable file integrity checks: 
    "EnableFsIntegrityChecks": true
  4. Try different graphics backend:
    • Switch between Vulkan and OpenGL
    • Some games work better with specific backends
  5. Check game compatibility:
    • Not all games are fully compatible
    • Check compatibility list or community forums
  6. Review logs:
    • Look for “Missing service” errors
    • Check for decryption failures
    • Note any ERROR messages
Common causes and solutions:
  1. Insufficient RAM:
    • Close other applications
    • Upgrade to 16GB RAM if possible
    • Don’t use 6GB or 8GB DRAM expansion unless needed
  2. Graphics driver crash:
    • Update to latest GPU drivers
    • Reduce graphics settings (resolution scale, AA)
    • Try different graphics backend
  3. Shader compilation issues:
    • Enable shader cache if disabled
    • Delete shader cache and rebuild: 
      <RyujinxFolder>/games/<TitleID>/cache/
  4. Mods causing issues:
    • Disable all mods in Mod Manager
    • Test game without mods
    • Re-enable mods one by one to find culprit
  5. Game-specific bugs:
    • Check if known issue
    • Try different game version/update
    • Report on GitHub if reproducible
Performance optimization:
  1. Enable PPTC (Profiled Persistent Translation Cache): 
    "EnablePtc": true
    • Requires 2-3 launches to build cache
    • Dramatically improves load times and stability
  2. Reduce graphics settings:
    • Resolution Scale: 1x or 2x
    • Anti-Aliasing: None
    • Disable texture recompression
    • Use Bilinear scaling filter
  3. Optimize backend:
    • Use Vulkan for best performance (if supported)
    • Enable shader cache
    • Set Backend Threading to Auto
  4. System optimization:
    • Close background applications
    • Disable browser, Discord, streaming software
    • Set Windows power plan to High Performance
    • Update all drivers
  5. Memory manager mode: 
    "MemoryManagerMode": "HostMappedUnsafe"
    • Default and fastest option
    • Try “HostMapped” if experiencing crashes
  6. CPU turbo multiplier:
    • Don’t change unless you know what you’re doing
    • Values over 100% speed up emulation but can break games

​
Graphics Issues

Solutions:
  1. Clear shader cache:
    • Navigate to <RyujinxFolder>/games/<TitleID>/cache/
    • Delete shader cache files
    • Restart game (cache will rebuild)
  2. Try different graphics backend:
    • Vulkan → OpenGL or vice versa
    • Different backends handle some effects differently
  3. Update GPU drivers:
    • Critical for graphics stability
    • Use clean installation if available
  4. Adjust graphics settings:
    • Disable texture recompression
    • Change anti-aliasing method
    • Try different scaling filter
  5. Check for overheating:
    • Monitor GPU temperature
    • Clean dust from cooling system
    • Reduce overclock if applicable
  6. Macro HLE setting: 
    "EnableMacroHLE": true
    • Try toggling this setting
    • Some games have issues with it enabled/disabled
Solutions:
  1. VSync mode: 
    "VSyncMode": "Switch"
    • Use “Switch” mode for proper frame pacing
    • Avoid “Unbounded” unless using VRR display
  2. Force VSync in GPU driver:
    • NVIDIA Control Panel: Manage 3D Settings
    • AMD Radeon Settings: Gaming > Global Settings
    • Force VSync on for Ryujinx
  3. Window vs Fullscreen:
    • Try switching between windowed and fullscreen
    • Some setups have better VSync in one mode
  4. Enable FreeSync/G-Sync:
    • If you have compatible monitor
    • May allow using Unbounded VSync without tearing

​
Audio Issues

For detailed audio troubleshooting, see the Audio Settings guide.Quick fixes:
  1. Change audio backend:
    • Try SDL3, OpenAL, or SoundIo
    • SDL3 is usually most reliable
  2. Check volume:
    • Ryujinx volume slider (Settings > Audio)
    • System volume mixer
    • In-game audio settings
  3. Audio driver updates:
    • Update audio drivers (especially Realtek)
    • Update motherboard chipset drivers
  4. Disable audio enhancements:
    • Windows: Sound Settings > Device Properties > Disable all enhancements

​
Input Issues

For detailed input troubleshooting, see the Input Configuration guide.Quick solutions:
  1. Connect controller before starting Ryujinx:
    • Ryujinx detects controllers on startup
    • Reconnect and restart if controller was connected later
  2. Reconfigure input:
    • Settings > Input
    • Remove and re-add controller
    • Remap all buttons
  3. Check controller in other applications:
    • Verify controller works in other games
    • Test with gamepad tester tools
  4. USB vs Bluetooth:
    • Try wired USB connection
    • Bluetooth can have latency/reliability issues
  5. Update controller firmware:
    • Check manufacturer’s website for updates
    • Xbox controllers: Xbox Accessories app
    • PS controllers: PC/Steam firmware updates

​
