2. Best Graphics Settings for Performance

Optimizing in-game graphics settings can significantly impact your frame rate and help to fix crashing issues in Cities: Skylines 2. Let's navigate through the settings menu step by step.

Go to Options > General

  • Performance Preference: Choose "Frame-rate" or "Balanced" for better performance. Experiment with both options to see which works best for you.

Navigate to Options > Graphics > Simple

  • Screen Resolution: While you can choose your preferred resolution, for better performance, stick to 1440p, 1080p, or lower. High resolutions (4K) can strain your system's resources, and it's important to note that at higher resolutions, the game's optimization tends to degrade, leading to a less-than-optimal experience. Therefore, opting for 1440p, 1080p, or lower resolutions is not only kinder to your hardware but also ensures that the game's optimization remains at a more favorable level, resulting in smoother gameplay.
  • Display Mode: Go for Fullscreen for improved performance.
  • VSync: Turn it off unless you encounter screen tearing issues.
  • Depth of Field mode: Disable it. This is one of the things that gives the biggest fps boost.
  • Dynamic Resolution Scale Quality: If you experience severe stuttering and struggle to run the game, try enabling Constant. Keep in mind that it sacrifices visual quality for better performance.
  • Volumetrics Quality Settings: Disable for a substantial performance boost.
  • Clouds, Fog, and Shadows Quality Settings: Lower these settings for smoother performance.
  • Ambient Occlusion Quality, Reflections Quality: Adjust to your system's capabilities.
  • Global Illumination Quality: Disable it.
  • Depth of Field Quality: Keep it disabled.
  • Motion Blur: Disable it.
  • Terrain Quality and Water Quality Settings: Lower them if necessary.
  • Level of Detail: Low or Medium.
  • Animation Quality: Adjust to a level that maintains fluidity.
  • Texture Quality Settings: Choose High or Medium based on your system's specs.

Options > Graphics > Advanced

  • Anti-aliasing Quality: Set it to Low.
  • Anti-aliasing Method: Use TAA for smoother edges.
  • Selection Outlines Multisamples: Set it to 2x.
  • Clouds Quality Settings: Lower these for better performance.
  • Directional Shadow Resolution: Consider setting it to 20.
  • Terrain casts shadows: Disable.
  • Level of Detail Distance: Keep it around 30%.

TLDR - Top Performance Boosters

  1. Disable VSync.
  2. Disable "Depth of Field Mode" for a rapid FPS boost.
  3. Disable the "Volumetric Quality Settings".
  4. Turn off "Global Illumination" and set "Level of Detail" to "Medium" or "Low" for increased FPS.
  5. For an extra FPS boost, disable "Terrain Casts Shadows" and reduce "Fog Quality."

3. NVIDIA Control Panel Settings

If you're an NVIDIA user, tweaking your GPU settings through the NVIDIA Control Panel can help further enhance performance and fix the low FPS and stuttering issues in Cities: Skylines 2.

  1. To begin, right-click on your desktop and select "NVIDIA Control Panel" from the context menu. This opens the control panel where you can fine-tune your graphics settings.
  2. In the NVIDIA Control Panel, navigate to the "Manage 3D Settings" section.
  3. Select "Program Settings" to configure settings specifically for Cities: Skylines 2.
  4. If Cities: Skylines 2 isn't already listed, click "Add" and then choose the game's executable (Cities2.exe).
  5. Power Management Mode: Choose "Prefer maximum performance" to ensure your GPU runs at full power when needed.
  6. Texture Filtering - Quality: For improved performance, select "High Performance".
  7. Vertical Sync: Set "Vertical Sync" to "Off" unless screen tearing is a significant issue, in which case you can set it to "Adaptive" for a balance between performance and smoothness.
  8. After adjusting these settings, make sure to click "Apply" to save your changes.

Note: If you prioritize a stable and stutter-free gaming experience over high FPS, you can lock the Max Frame Rate to 30 in the NVIDIA Control Panel. As you progress in the game and expand your city, the FPS naturally tends to decrease significantly due to the increasing number of buildings and complexities. For many players, locking the FPS to 30 can be the optimal solution to ensure a consistently smooth gameplay experience without worrying about fluctuating frame rates.

These NVIDIA Control Panel settings should help you fine-tune your GPU's performance specifically for Cities: Skylines 2, ensuring a smoother and more responsive gaming experience. Remember to experiment with these settings to find the perfect balance between performance and visuals that suits your system.

4. AMD Software Settings

Similarly, if you're using an AMD graphics card, access the AMD Radeon Software and optimize your graphics settings to improve the game's performance.

  1. In the AMD Radeon Software, navigate to the "Gaming" tab and click on "Add a game" to create a profile for Cities: Skylines 2.
  2. Locate the Cities: Skylines II executable file (Cities2.exe) and select it.
  3. Set the specific graphics settings for Cities: Skylines 2 as follows:
    • Anti-Aliasing Mode: "Use application settings"
    • Texture Filtering Quality: "Performance"
    • Wait for Vertical Refresh: "Always Off"
    • Tessellation Mode: "Override application settings" and set "Maximum Tessellation Level" to a lower value.
    • Frame Rate Target Control (FRTC): If you prefer a capped frame rate, set your desired target.
  4. Once you've configured the settings, click "Save" to keep this profile for Cities: Skylines 2.

By creating a specific profile for Cities: Skylines 2, you can fine-tune your AMD Radeon Software settings to provide the best performance and fix the stuttering and low FPS issues while playing the game. Experiment with these settings to find the ideal balance between performance and visual quality that suits your gaming experience.
