Steamdeck-Ultimate-Windows11-Guide VS Playnite

It's worked perfectly fine for me, just follow this guide.

All the latest information about it should be in https://github.com/baldsealion/Steamdeck-Ultimate-Windows11-Guide/wiki

I went through the same thing, and every source I read said it's best to install windows to the SD internal memory and use SD cards only for additional storage to whichever OS needs it. I used https://github.com/baldsealion/Steamdeck-Ultimate-Windows11-Guide/wiki/1.0-Getting-Started, and then ran https://github.com/CelesteHeartsong/SteamDeckAutomatedInstall

And follow this guide for setting up windows for the best experience.

I've done something similar before with Playnite (an open-source PC game library manager), which has an HLTB plugin.

Playnite: The one with the most features and libraries available via addons and has a lot of options for customization. In my opinion the best one available for this purpose.

Here's a project for Playnite 11: https://github.com/JosefNemec/Playnite/milestone/9

As for my LGO, the only other app I've installed outside of the standard launcher was Playnite to consolidate all games into one place as Legion Space doesn't detect everything I have installed and I don't want to manage manually adding games to their launcher.

use playnite instead of the individual launchers.

Here is where I come in and recommend everyone check out Playnite: https://playnite.link/

When I care about supporting a developer or publisher and they offer their product on their own storefront DRM-free, I will often go there to buy. Or I buy from GoG which takes a smaller cut. Playnite lets me launch my Steam and non-Steam games in a seamless fashion. Steam still does a great job as a game installer/patch manager, and helps me discover new games. But I'm not locked into paying them a 30% fee, which is pretty brutal for some smaller publishers.

For anyone with any of the myriad of HDR monitors that prefers to leave desktop mode in SDR RGB, I just discovered that the excellent Playnite game launcher has a feature where you can enable HDR on a per-game basis. Simply tick the "Enable HDR support" option under "Advanced" tab for the settings of the games that you want HDR turned on for. I was previously using the now-abandoned AutoActions for this, so glad to see there's an alternative in a tool I already use.

Not exactly what you are looking for, but I've been using Playnite to launch everything on my computer for years.
