Why Unreal Engine 5 Titles Stutter on PC
Modern titles utilizing Nanite geometry and Lumen dynamic illumination compile Pipeline State Objects (PSOs) on-the-fly when encountering new materials. When this happens during gameplay, frame times spike from 14ms to over 75ms, perceived by human eyes as a jarring hitch.
The 10GB Nvidia Driver Cache Tweak
- Open NVIDIA Control Panel > Manage 3D Settings > Global Settings.
- Scroll down to Shader Cache Size.
- Change from the default Driver Default (4GB) to 10 GB or Unlimited.
- Click Apply and restart your system.
This allows your system to retain pre-compiled shaders across game patches and driver updates without forcing annoying in-game recompilation.
