01.Why Does Genshin Impact Stutter?
Even on powerful PCs, Genshin Impact can suffer from tiny stutters when loading textures for new environments or particle effects from new attacks (Bursts). This happens because the game uses the Unity engine, which sometimes struggles with real-time asset streaming from slower HDDs or SSDs.

02.1. Shader Cache Optimization (NVIDIA/AMD)
The most effective solution is to provide more space for the driver to store graphical calculations:
Go to your NVIDIA Control Panel > Manage 3D Settings > Look for 'Shader Cache Size' and set it to 10GB or Unlimited. This drastically reduces the stuttering that occurs the first time you use a skill in each gaming session.
03.2. Settings That Eat FPS
- Render Resolution: Keep it at 1.0 or 0.8 (if your PC is very weak). Above 1.0, the performance hit increases exponentially.
- Shadows: Low. Shadows in Genshin are processed by both the CPU and GPU simultaneously.
- Visual Effects: Medium. At High, FPS drops whenever multiple characters use Bursts together.
- Bloom: Disable (This helps with visual clarity and provides a small frame boost).
04.3. Process Priority
Open Genshin Impact, minimize the game, and open the Task Manager.
Go to the 'Details' tab, find GenshinImpact.exe, right-click > Set Priority > Above Normal. This ensures Windows gives special attention to the game over useless background processes.
