steam-deck-tools VS Playnite

I use Steam Deck tools for windows for all my deck buttons and shortcuts https://github.com/ayufan/steam-deck-tools

It's friendlier than it looks! First download the latest Steam Deck Tools release from GitHubsteam deck tools, then install RTSSrtss so the overlay and quick menus work, and optionally follow thisvrr guide to get VRR working. Make sure they're all set to run on startup and you should be good to go. The options all live in the task bar, and you can easily toggle between desktop/controller mode and different fan profiles, refresh rates, etc. It takes some fiddling around to get perfect but it has most, if not all, of the functionality of the native OS

Are you sure you are actually using Windows on the deck? Because except for getting the controller working in 3rd party launchers (which needs this single tool: https://github.com/ayufan/steam-deck-tools) - there were absolutely NO errors / hurdles at all. Everything just works as expected.

I prefer Steam Deck Tools for Windows https://github.com/ayufan/steam-deck-tools this is free, and adds pretty much full Stream Deck functionality to Windows. Steam Deck shortcuts for bringing up the windows keyboard, closing apps, alt tabbing, bringing up an overlay, using the overlay to choose frame rate and scaling options, etc, etc.

Steam Deck Tools I launch Diablo hold start and swaps to controller mode.

Install https://github.com/ayufan/steam-deck-tools This gives you control of fans, power limits, controller/mouse mode, etc. Its an all in 1 tool

And I use Steam Deck Tools for Windows for everything else and it works great https://github.com/ayufan/steam-deck-tools

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.
