I played them just fine on Windows but I guess nothing can be done. Thanks for the help though
Maybe an older version of Proton or Proton GE could help you out for the moment.
I found this report about an older version working on a more vintage hybrid system:

it might be harsh but i can understand that a company will end supporting a product after a decade.
and sorry, if i wanna game i need a powerful gpu, that’s fact.
i can understand if someone runs such a card for office-applications and some youtube-videos, but the specs do not fulfill the recommendations for nowadays games, so nvidia stopped supporting it.
