Do you render on internal or external display with the eGPU?


It's in a minipc so there is no internal display. The system is reconfigured to run everything on the given device and the monitor is plugged into that device for these tests. So for the 780M the monitor is plugged into the minipc ...

2 guesses:

1. You're running much higher graphics settings with the 7800XT
2. One is an Nvidia GPU and the other is an AMD GPU and you're on linux which means you get that whole experience with drivers.


1. The settings are the same, maxed out I guess in both cases though when trying various ...

I am experiencing a very odd behavior with Factorio where a very beefy GPU is seemingly unable to render 60fps while the much more modest iGPU is blazing away at 200fps.

Somehow Slow

Fast iGPU

This behavior seems consistent across sway/gnome. In both cases I started the compositor on the same ...
