I am running a setting where I am using an eGPU (RX 580) box on a Yoga 920 (i7-8550u). In Windows 10 this nets me very decent performance, on medium settings easily surpassing 100 FPS.
Using Wine Staging 5.19 with the Lutris default install script and using the
DRI_PRIME key with value
1 to enable the eGPU I don’t get anywhere near that performance. I think the eGPU is being used, as I’m still getting 30-40 fps, however this can very easily dip and I think the frame-times are also bad as it does not feel consistent.
