Seems like the UE5 games can’t get steady framerates on most hardware, but I know what you mean.
I’m definitely looking forward to steam deck 2, but I do appreciate that Valve isn’t pushing out a new one each year with slightly improved specs. And now that the nintendo switch 2 has about the same power as the steam deck, maybe we’ll see UE5 and some other engines actually try to run well at that performance level.
It’s not hard at all, if you’ve done any kind of tech disassembly before you should be good. Just make sure you don’t strip the screws (don’t use a screwdriver that’s too small, make sure it’s all the way in the screws before turning it).
You will have to either clone the drive or install SteamOS fresh on the new SSD from a USB drive. They may have fixed it, but originally the SteamOS installation/recovery USB had a software bug that would crash the wifi driver if you connect to a 5GHz wifi 6 network. So if you have a WiFi 6 network, I would suggest only connecting to the 2.4Ghz version of it until you’ve completed setup and downloaded updates.
If you clone the drive you don’t have to worry about that, but sometimes after cloning you have to realize the cloned partitions to actually take advantage of the larger drive.
If you run into any of those issues and need help, feel free to reply to me here and I’ll do my best to help out.
