Optimizing GPU Memory Usage in Unity on Windows 10
Understand Your Requirements
Before optimizing, it’s critical to assess your game’s graphical requirements and the available GPU resources. Use tools like Profiler in Unity to monitor GPU usage.
Lower Resolution Settings
- Reduce in-game resolution to decrease the load on the GPU.
- Implement quality settings in your game to allow players to adjust based on their system capabilities.
Disable Shared GPU Memory
If possible, configure your Windows 10 settings to prioritize dedicated memory usage over shared memory, notably by tweaking the BIOS settings to allocate a fixed amount of dedicated GPU memory.

Texture Optimization
- Use texture atlases to reduce draw calls and save memory.
- Compress textures using appropriate formats, e.g., DXT1/DXT5 for Direct3D.
Efficient Memory Management
- Unload assets that are not in use with the
Resources.UnloadUnusedAssets()function in Unity. - Manage asset lifecycles carefully, ensuring objects are not lingering in memory unnecessarily.
Advanced Graphics Settings
Utilize Unity’s graphics settings to optimize rendering, such as adjusting LOD (Level of Detail) settings and using Occlusion Culling.
Adjust Windows 10 GPU Settings
Navigate to ‘Graphics settings’ in Windows to allocate GPU resources adequately and manage shared GPU memory.
Monitor and Test
After implementing changes, consistently test your game under different conditions to ensure stable performance and adjust settings based on profiling results.
