Troubleshooting
Intel Turbo Boost and eGPU Stuttering
When connected to an external PCIe device (eGPU), Intel Turbo Boost may cause micro-stuttering. The stuttering appears to be related to how the CPU’s power or frequency scaling interacts with the eGPU, which does not occur when using the internal display. To resolve this issue, disable Intel Turbo Boost in the Performance section of the UEFI firmware.
