fpPS4 VS steam-deck-utilities

PlayStation 4: fpPS4 is the best PS4 Emulator according to the emulation wiki (PS4 Emulation is very early in development so it's not recommended you use PS4 emulation): Download fpPS4

Yes, in fact the PS4 is beginning to see HLE with various emulators, most notably fpPS4 (free pascal PS4).

There's a couple actually. Spine was the most impressive at the time of its last release, but it's been about a year since that release and whether it's still being developed is still unknown. fpPS4 and Obliteration seems to be the most promising right now.

PS4 emulation is in the works, but playing something like Ghosts of Tsushima is years away. fpPS4 and Obliteration are experimental emulators / compatibility layers, but they’ve only been in development for a few years and can just boot simple games. That being said, Ghost of Tsushima was one of many games listed in the GeForce NOW leak from Ighor July a few years ago; Since then, many of the games listed have indeed been announced for PC, so a PC port might be on its way.

There's a PS4 emulator being developed in Pascal. For real.

CryoUtilities for performance optimization.

First you will need Cryoutilities installed. Set it up and set the recommended settings. There is a guide on how to set VRAM to 4gb in the video for Cryoutilities, so do this as well. Next install the Starfield Potato Mode Textures Mod and use the 256 bit version for slightly better quality (the standard version is a bit better performance but I don’t like the muddiness of the textures).

Then I installed the CryoByte utility as described here: https://github.com/CryoByte33/steam-deck-utilities (also worked fine).

CryByte33 utilities app. Pay attention that you will need to apply 4G graphics memory fix from Steam Deck BIOS too.

CryoUtilities will let you keep the shader cache on the same storage device the game is installed on. I still think an SSD is a worthwhile upgrade but I thought that was worth mentioning.

Use https://github.com/CryoByte33/steam-deck-utilities to move your game's shader caches to the drive each game is on, instead of the default 64gb ssd.

INSTALLATION: To install Cryo Utilities, make sure you have a sudo password already set otherwise it cannot perform tweaks necessary for this to work. 1st download the installer here: CryoByte33/steam-deck-utilities: A utility to improve performance and help manage storage on Steam Deck.
