The Linux graphics stack in a nutshell, part 1
I think your information is quite outdated. The HWC overlay planes are heavily used, you can see this trivially just doing a 'dumpsys SurfaceFlinger' or grabbing a systrace/perfetto trace. When it falls back to GPU composition it's very obvious as there's a significant hit to latency and more GPU contention.
The overlay capabilities of the modern Snapdragons are also quite absurd. They support like upwards of a dozen overlays now and even have FP16 extended sRGB support. Some HWCs (like the one in the steam deck) even have per plane 3D LUTs for HDR tone mapping (ex https://github.com/ValveSoftware/gamescope/blob/master/src/d... )
The composition is bandwidth heavy of course, but for static scenes there's a cache after the HWC in the form of panel self refresh.

Firefox Is Going to Try and Ship with Wayland Enabled by Default
One of the unfortunate things about Wayland is every compositor will have its own quality of implementation affecting things like latency.
With XOrg, especially in the pre-compositing days, you could choose whatever WM you want and it wouldn't have any impact on the rendering performance of X clients. Once the Composite extension was added and everyone started running composited X desktops, that started to change, and the increased latency already started appearing - in an arguably worse architecture than Wayland because there were often three processes involved with lots of IPC per draw: X-Client->X-Server->X-Compositor->X-Server->CRTC. At least in Wayland it's more like Wayland-Client->Wayland-Compositor->CRTC.
If you're unhappy with the rendering latency of your Wayland sessions, it may be worth trying alternative compositors... they likely vary significantly. The Valve/Steam folks have made a minimal one specifically optimized for games/low-latency [0]. I doubt the SteamDeck would be seeing as much success as it is if Wayland were so problematic in this department.

Help needed to confirm two 3.5 bugs
While streaming from the Deck to another device (phone with Steam Link app or another PC running steam), taking a screenshot on the Deck (hold the steam or ... button, and press R1) crashes the session (https://github.com/ValveSoftware/gamescope/issues/961). This one also impacts Decky Recorder. If you're recording the screen or have replay mode on and take a screenshot, you'll have a crash.

Force V-Sync or limit fps in proton games
Mangohud (GOverlay), libstrangle, gamescope. Pick your poison.
- Why is it taking so long Valve, hurry up and put 3.5 on preview pretty please, I am dying waiting grrrrr

More Than 75% of Steam Games Tested Are Playable or Verified on the Steam Deck
I have an Intel GPU (HD Graphics 520) and gamescope doesn't work for me under arch Linux :( https://github.com/ValveSoftware/gamescope/issues/356

Gamescope not working in Ubunte
Hopefully someone more experienced in troubleshooting than me can chime in to help, since I don't wish to leave you on a "Works on my machine™" but I really don't know how to help since I don't use Ubuntu. In the meantime, try opening an issue on gamescope's issue tracker.
Take a second look at the github page; there is information on how to set the right resolution with Steam launch arguments. A quick cursory glance at the documentation gives me the impression that support for Nvidia GPU's is limited. I wouldn't bother with it if you consider yourself a Linux noob, the small performance up lift in not going to out way the frustration to make it work properly.

Help Request: Low Framerate in Cyberpunk 2077 on RX 7900 XT
I'm unfamiliar with gamescope, never heard of it before. I found their github... I'm guessing "command" needs to be a compatibility layer like proton or wine calling the game's executable, huh?

Bookworm and games
In a nutshell, the video stack is held back because of compositor ; YMMV, but, if you'd like to try one designed primarly for games, use gamescope, the one made for the Steam Deck: https://github.com/ValveSoftware/gamescope

My monitor runs at 144 Hz but games that should be at 60 FPS play too fast. How can I lock it?
There's probably a million different ways to limit FPS. I use GOverlay as a front-end for MangoHud, and limiting FPS in it is extremely simple. Simply change "FPS Limit", Save, and you're good to go. Use the selected hotkey (F1-F4) to enable/disable the limiter (and right shift + F12 to show/hide MangoHud itself)

How to increase contrast for games
Many people seem to use GOverlay as a GUI to configure it. I do it manually because when I tried GOverlay long ago it wasn't ready yet, but maybe it's good now, try it if you prefer a GUI.

Upgrade Help Thread
I was just clicking the icon in the application menu but it wouldn't launch. However I came across the issue in Github: https://github.com/benjamimgois-zz/goverlay/issues/203 , I used the .deb file as suggested and i'm able to use the program again.

FPS/performance overlay appearance
GOverlay is a GUI application that can be used to manage the config

Steam Deck vs. Switch OLED vs. Switch Regular
Would be interesting to see what the deck would look like with Reshade's fakeHDR or other options. Even the fakeHDR option makes a big difference in contrast and vibrancy. On Linux Reshade is called vkBasalt and can be configured with gOverlay. Don't know if that's available already via SteamOS.

game performance
A lot of people use an onscreen monitor. MangoHud is good you can use GOverlay to edit and alter MangoHud. https://github.com/benjamimgois/goverlay , https://github.com/flightlessmango/MangoHud ,

Can steam deck record gameplay?
There is a tool called ReplaySorcery (https://github.com/matanui159/ReplaySorcery) which you can configure with GOverlay (https://github.com/benjamimgois/goverlay).

GOverlay 0.7
There will be hotfix incoming - https://github.com/benjamimgois/goverlay/pull/167
-
does anyone have any clipping softwear i can use
ReplaySorcery, its also a dependency for GOverlay that is highly recommended.
