Hello, my name is Eric and I would like to introduce myself first. Flight Sims are not completely new to me, but I just started with flight gear.
On my main PC I use an older Nvidia card and an Intel CPU. I use all of that under arch linux without any problems. my old GTX 960 doesn't cause any problems with the nvidia proprietary driver.
However, my laptop uses an Intel / Amd hybrid solution. when I start flight gear normally, the integrated intel iGPU is used for rendering. for a better performance i want flight gear to use the amd graphics.
other programs using it with "DRI_PRIME = 1" but the flight gear GUI just stop loading after a few seconds.
The GPU is a AMD R5 M330 and I use the open source "amdgpu" kernel module. any idea what I'm doing wrong? many thanks for your help
