How to resolution issues? (sh.itjust.works)

Hey guys, I just got my Steam Machine and, having never owned or used a Deck, I want to know how you guys are tackling the resolution issue.

It’s hooked up to a 4K 165Hz monitor, which I know is not something the Machine can ever hope to achieve in modern 3D games, but it IS capable of it in the Steam interface and in 2D or old 3D games (majority of games I play).

Issue #1: The performance overlay is too small. I haven’t figured out which of the scaling options affect it (if any)

Issue #2: Some games don’t have AI upscaling, or have it hidden when they detect they’re running on a “Steam Deck”. I tried Another Crab’s Treasure, which barely runs at 30-40fps at 4K, but often hits 120 at 1080p with high settings. Blurry text is the bane of my existence, and I’m seriously conflicted about which resolution to use. Is there any way to inject FSR(4) into games that don’t already support it?

Issue #3: Proton. By default, do games have their Proton version set per game, or globally? Asking because I assume a proper “verified” program would tag the tested software version, but you never know. Is there any risk to setting games to use the latest version? How common are feature/compatibility regressions?

Any tips and tricks welcome, i’m a complete noob when it comes to SteamOS

There is a way to inject FSR 4 into games but only if they already support another upscaling algorithm like FSR 3 or DLSS. Don't know about the Steam Machine/Deck specifically but in general it's called optiscaler. I bet there is a Decky plugin to make it easier to activate.

There is a decky plugin for it, called Decky-Framegen. It originally just enabled frame gen but now installs optiscaler.

There's also a new plugin called Proton Launch that seems like it lets you toggle various proton/GEproton options, including optiscaler, FSR upgrades, various performance settings (DXVK async, low latency, etc), and more.
