the original author already has a pull request open for it:
Right, there's no point in tracking this as a general feature request when there's already direct communication between the patch author and the Proton devs. Closing in favor of https://github.com/ValveSoftware/wine/pull/116.
Feature Request
FSR hack support for mainstream proton
I confirm:
contain this feature already.
Description
I have used proton_FSR hack in a custom proton version called proton_ge and it works great. The best part is it works on all games(Only Windows games that run through proton) even if it(the game) doesn't have fsr by default.
Justification [optional]
Because it depends on how proton works rather than wine based on the documentation of the feature in proton_ge
Risks [optional]
unknown as of now
