Hi,
I have a Asus R900V with a Geforce GT 630M. This laptop has a Nvidia Optimus technology (hybrid Intel/Nvidia graphic rendering). It is old but works very well but I cannot run any games on Steam that use Proton.
For example, for Kards :

Same issue with Total Annihilation, it doesn’t run (I set everything in Steam to allow Proton, I did it on other computers).
But Tomb Raider (2013) works … I think, it’s because of its native runtime. It doesn’t use Proton but at start-up a warning is display about the driver (may be not optimal, etc …).
I’ve look into the drivers and I saw that I’m using Bumblebee drivers :
$ mhwd -li
video-hybrid-intel-nvidia-390xx-bumblebee 2021.12.18
I think it may be because of this driver (but I’m not sure of it). So I’ve read a lot about it in the past few day but I’m not sure the tutorial is up-to-date : [HowTo] Set up PRIME (output offload) with NVIDIA proprietary driver.
I don’t want to go into something complicated if I don’t need to. I try to disable the Intel GPU from the BIOS but it seems that I can’t 
So my question is : what is your advice for this setup ? Do you think that if I setup a NVidia-Prime configuration, it will fix my issue with Steam ?
