Feature Request

I confirm:

  • [ yes] that I haven't found another request for this feature.
  • [yes ] that I have checked whether there are updates for my system available that
    contain this feature already.

Description <!-- The ability to set a default/higher DPI for any newly generated Proton prefixes.

For example, when launching games with launchers on displays higher than 1080p, the DPI is always incredibly small, meaning you need to get really close to the screen to read anything and it genuinely causes me eye strain. Or let's say you need to use an installer for a mod or some kind of tool and you need to run it within the Proton prefix via protontricks, or a mod manager etc. Same deal, the DPI defaults to something really low. Only way to fix it is to manually set your DPI for literally every single newly generated proton prefix in Protontricks as far as I know which is incredibly annoying to say the least, as someone who does a lot of game modding and a lot of playing/tweaking/patching of older titles.

Steam should allow us to set a default DPI for any new proton prefix created, perhaps somewhere in the settings menu. I know this is at least possible theoretically because my default system wine prefix has a DPI set to my liking and resolution so anything I open with the normal Wine program loader loads properly with DPI that I can actually read, along with Bottles etc. it's incredibly annoying to have to do this for any given game I want to do anything with other than play it or drag and drop mods in to the local files. Heroic and even Lutris (which is from what I understand semi abandoned) let you do this, so I feel like this feature is a no-brainer for inclusion. I'm surprised I wasn't able to find anyone requesting it already, but maybe I'm not that good at searching. -->

Justification [optional]

Risks [optional]

None. The only thing I can think of is the fact that it would need to be per machine not per account, but that doesn't seem difficult to set up.

References [optional]

The ability to easily access Proton prefixes from within Steam itself is sorely needed and I plan to make another issue for this specifically. The way it works now you basically either need to go to PC gamingwiki to get the actual Proton prefix ID that the folder is entitled with or, I recently realized, Protontricks actually shows the ID so you can manually navigate to it. We should be able to right click see an option like "browse prefix" just like the option to browse local files. If you don't want to crowd the context menu too much for the normies, make it a toggle that's off by default. It's especially important for games that, for example, store their saves within their prefix or literally anything done in the actual prefix, I.E. too many titles to name here. This is a related issue but I'll probably make another feature request just for this one, but overall more control of our Proton prefixes is something that I think is becoming increasingly necessary as more and more people not only move on from 1080p but want more control over their games.
