This has to be the worlds dumbest, I hate to even call this a solution, to get Ratchet and Clank running.
BIOS: VRAM 6GB (I keep it at that anyway)
Windows Res: 1280x800 but higher works fine
Game:
Fullscreen (NOT Exclusive, at least I haven't tested it because I use lossless scaling)
Resolution: 1280x800
Aspect: 16:10
VSYNC: ON
Frame Gen: OFF (Stuttery mess, Lossless Scaling works better anyway).
Upscale: FSR 3 (or DLSS for better fps if you know how to force it, not getting into that here)
Quality: Balanced
Dynamic Resolution: Off
Graphics : I have everything pretty much as low as it goes. Still looks perfectly acceptable and get nearly solid 60fps.
NOW FOR THE STUPIDNESS: Your Windows page file needs to be 40GB. 24GB has about a 15% success rate, 40GB it loads up fast and perfectly every time.
So last night was a fluke. There's more to get getting it playable and it all seems graphical related. And even with the below ADDITIONAL Fix you are bound to crash. About every 15 minutes.
First you need to go into regedit
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
New > DWORD (32-bit) Value of 0. Disables Crash checks.
Reboot.
Go into the the game folder for Ratchet and Clank. Rename dstoragecore.dll and dstorage.dll to each dstoragecore.dll.bak and dstorage.dll.bak.
We don't want to get rid of these, this just keeps them safe.
WITH ALL THAT SAID, even if you could tolerate crashes every 15 minutes, constant writing to the page file in 40GB chunks will degrage your drives love unnecessarily.
I dont know of this is another poor Sony port and/or Z1 Extreme blunder. Happens with Lenovo and AMD drivers. I give up. Perfect on the go game but not worth the aggregation.
