Many thx for your suggestions.

Many THX. That’s exactly what I have searched for. I was confused by frame_timing.

Yes, I think the card is the weak point here or better the weak driver support. My next laptop will definitely have a AMD card. But I have absolutely no idea which one is good enough to handle actual games with full details and usable fps. I don’t expect Desktop like experience but at least 40 fps with full details in an actual game would be fine. Im not a professional gamer, but when I have the time to play, it should be fun and not frustrating. Mostly I do coding with VSCode and some database stuff in different flavors. So a not to small display is a must have.

Can you recommend a good GPU? For the rest I can do my own research…

Yes, of course. But nothing helped really. There is a small difference between the used Proton version. With 8.25 GE i get 13 fps and with 6.4 GE1 i get 19 fps. Using PROTON_USE_WINED3D11=1 makes it more worse than ever, with only 5 fps.

On the same laptop with windows, I have ~ 60 fps.
