## AI overview

A laptop-based eGPU setup with an Nvidia 3080 caused severe stuttering in HTC Vive VR games despite the GPU functioning correctly. The article attributes the issue, with uncertainty, to Nvidia Optimus polling the laptop's other graphics hardware and interfering with smooth eGPU rendering.

## Source excerpt

eGPU stutter from hell I was able to put my hands on an HTC Vive VR headset. Sadly, my computers don't have a strong enough GPU for VR. Since I only have laptops I decided to secure an eGPU (external GPU) - a box with PCIe bus, connected over thunderbolt, which can house a proper big graphics card. I got Razer Core X.
