ProtonDB now has separate tabs for easier browsing of Steam Deck or PC reports. You can also view a combined tab that includes reports from both.
Both categories can be pretty useful, but some game fixes can only be found in the PC section. A lot of the PC report creators are more experienced Linux users and know of fixes that may not show up in the Steam Deck section.
This is the best summary I could come up with:
ProtonDB is the go-to for a lot of people to see how games run on Linux desktop and Steam Deck, and while its rating system is far from perfect it’s nice to have.
A recent upgrade also makes it a lot nicer to browse.
When the Steam Deck released ProtonDB added dedicated Steam Deck reports to game pages, which ended up making it quite a mess - especially for PC players where every page would have you scroll and scroll until you go to the desktop Linux reports — but no more!
There is now a tabbed submenu above reports on game pages.
In this menu, you can now filter by PC, Steam Deck, or a combined list.
When you select an item in the device submenu, the URL is updated and can be shared to send someone directly to reports corresponding to your selection.
