moonlight-docs VS Playnite

I actually have a setup a cool gamepad layout using steam so controller is not an issue, I already play with a controller on my PC. The issue is streaming quality. I've tried with Moonlight and Steam Link (using NVIDIA SHIELD GameStream like this)

You need to install nvidia game experience on your PC, and moonlight on your shield, then follow instructions from the setup guide

There is a guide on how to do it: https://github.com/moonlight-stream/moonlight-docs/wiki/Setup-Guide

Moonlight can also stream your local games over Internet so you dont need to be on the same Wifi network, but that requires an additional software on your PC. Check the guide here (scroll down to Streaming Over The Internet): https://github.com/moonlight-stream/moonlight-docs/wiki/Setup-Guide/2e7b42f5c37fcaef103ef64e893d0964069d7ffe

Is it an nvidia graphics card? If so ive had better success with moonlight. https://github.com/moonlight-stream/moonlight-docs/wiki/Setup-Guide Ive gotten 120fps 1080p streaming with 0 frame loss

Not particularly, especially since you likely already have NVIDIA GeForce Experience installed. You can follow the setup guide here. It may look daunting, but it's really just a variety of alternatives if the automatic configuration doesn't work or you want a specific configuration.

you can also read moonlight’s page about it

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.
