I know. I try to explain better. My laptop has the intel integrated graphics and the nvidia dedicated. From PopOs I usw the hybrid mode, zo both the card are running. From lutris and heroic I have no problem. I switch the toggle andthe game will run with the nvidia card. From steam all the games that will use proton use the nvidia card as default. While all native linux games not, they will use the intel ones if not specified.
The problem are only native linux games runned trought Steam. In hybrid mode they will not use the discrete graphic card. For the rest I have no problem
