It looks like the special set of graphic settings for Cyberpunk 2077 running on Steam Deck is not working properly. When it is selected, the game can run at just 20 frames per second.
Recent patch 1.52 for Cyberpunk 2077 has quietly added support for Steam Deck. Along with it the game received new options on Valve's console , a special set of settings called "Steam Deck".
In theory, Steam Deck owners who aren't interested in manually adjusting each visual option individually can choose this predefined set and enjoy the optimal balance between performance and image quality.
A YouTube user nicknamed Gaming On Linux posted a video, in which he shows that this "preset" does not always work as it should.
AMD FidelityFX Super Resolution (FSR for short) drastically increases the frame rate, with almost invisible image degradation.
Gaming On Linux sums up the situation:
"If people using Steam Deck were to go into the settings, find an option called 'Steam Deck' there, and then learn that it works really badly - that wouldn't look too good.
YouTube user C0haagen also posted a benchmark video from Cyberpunk 2077 with selected Steam Deck settings (at 1280x800 resolution):
Both youtubers use the MangoHud tool to measure the frame rate (it is visible in the upper left corner of the screen). Although in C0haagen's case it incorrectly shows that the FSR is disabled, at the beginning of his video we see clearly that he enabled it in the game options.
So it looks like the Steam Deck graphic preset was supposed to correspond to the "ultra" setting with the difference being FSR enabled. The problem lies in the fact that selecting it does not automatically enable the latter.
At this point everything indicates that in order for Cyberpunk 2077 to function properly on Steam Deck, all you have to do is adjust the graphic settings yourself, choose a preset from the "low" to "high" or "ultra" range, or "Steam Deck" with FSR technology enabled.
CD Projekt RED (the game's creators) is probably aware of this situation, as the game's card on Steam includes information that Cyberpunk 2077 is playable on Valve's mobile device, but requires manual configuration of graphic settings in order to run efficiently.
Gaming On Linux posted the following comment under C0haagen's video:
"Disable FSR, restore the default settings, and then set the graphic options to Steam Deck option. Then restart the game and turn on the benchmark. What result do you get? Something is wrong here, because the graphics in your video look much worse (even taking FSR into account) than in mine."
After that he specified it in the comment under his video:
"Update: upon closer investigation, it turned out that the Steam Deck setting is definitely not working properly. By itself, it simply contains the same options as the ultra preset, but there is more to it than that.
Switching directly from the medium preset to Steam Deck and running the benchmark, I found the performance to be higher than what I posted in my video (...).
It seems that Cyberpunk sticks to the graphic settings you had before you selected the Steam Deck option, and any restart of the game after choosing that preset resets them back to ultra."
