Freddy Benchmarks Cyberpunk 2077 2.5 on Steam Deck OLED's New OS
A Steam Deck OLED runs Cyberpunk 2077's 2.5 update on SteamOS 3.10 with nothing touched but the OS and Proton, and the test splits XeSS from FSR across two frame targets.
A new operating system build and a major patch landing in the same week is exactly the kind of coincidence that should make anyone with a Steam Deck nervous, because 'update' is a word marketing loves and compatibility layers love to punish. FreddysGamingBenchmarks ran the obvious test: drop Cyberpunk 2077's 2.5 patch onto a Steam Deck OLED running the freshly pushed SteamOS 3.10, touch nothing else, and see what Proton does with it.
The test methodology is the one part of this worth dwelling on, because it's the correct one. The channel's rundown is explicit that the Deck runs with 'factory settings', meaning only the OS update and Proton get credit for whatever happens on screen, no custom tuning, no community config pulled off a forum to flatter the result. That's the difference between a benchmark and an ad, and it's rarer than it should be.
What actually got tested
The video from FreddysGamingBenchmarks runs through a specific sequence rather than a single number, which tells you the real question here is upscaler behavior, not a headline frame count:
- Proton setup and launch, the step everyone skips until it breaks
- Graphics settings as shipped, before anything gets touched
- XeSS upscaling with the frame rate capped at 30
- XeSS again with no frame cap at all
- FSR with no frame cap, run back to back against the XeSS pass
Putting XeSS and FSR through the same uncapped run on the same silicon is the useful part. Intel's upscaler landing on a Deck at all is still a relatively new wrinkle for SteamOS, and whether it holds its own against Valve's long-favored FSR on the same patch is a fair thing to want answered before you go flipping that setting yourself.
Why the 'factory settings' line matters
Cyberpunk 2077's 2.5 update has already been the subject of plenty of coverage on this site, including the patch notes around its new dual-wielding mechanics, but a feature list doesn't tell you whether the thing survives contact with a 7 inch OLED panel and a locked 15 watt power budget. That's a hardware question, not a patch-notes question, and it's the one this run is actually built to answer.
Freddy's channel also has a separate walkthrough on getting to SteamOS 3.10 in the first place, which is worth a look before anyone updates a Deck mid-playthrough and finds a save file or a control scheme behaving strangely. Test your own rig before you trust someone else's chapter markers, but at least this one shows its work on what wasn't changed.
