Let's do some performance testing of #Steam Game Recording!
Starting off on #SteamDeck LCD with Shadow of the Tomb Raider. I ran the benchmark at MED quality preset with Game Recording off, then Background Game Recording on and recorded results for the *2nd* run of each. I also ran each set of benchmarks twice to ensure I saw the same results.
For this example, we're seeing a 5% performance hit.
(In results screen, you can see the GPU working just a bit harder w/ recording on.)
More to come.

I'm testing Steam Game Recording on Windows now. This is Shadow of the Tomb Raider with the same 1440p/Highest setting as on Linux/Bazzite. Here, you can see the performance hit is only 13% with background game recording ON.
This is the way it *should* be, so I'm convinced Steam on Bazzite is using software encoding and not hardware encoding for this AMD RX 6800M.
I'll definitely be testing this on another more vanilla distro to see how things compare.

OK, so back to the gaming laptop and Shadow of the Tomb Raider. Does that massive 37% performance hit scale down as expected when lowering resolution and quality?
I reduced the output to 720p on my gaming laptop and switched to the Medium quality preset to somewhat mirror the Steam Deck test.
I'm now seeing a performance hit of 19% when enabling Game Mode. I still think it should be considerably less on hardware this powerful 🤔
Thoughts?
More testing required!
(thanks for the idea @root)

Back to the Steam Deck for now, testing Cyberpunk 2077 (using the Steam Deck quality preset). Can confirm the EXACT same performance hit of 5% (producing an average 42FPS during the benchmark) when switching on Game Recording. Which is an impressive result!
(Next up, I'll bounce back to the gaming laptop for Shadow of the Tomb Raider -- but this time running it at the same resolution and quality settings from the Steam Deck runs.)

Whoo boy. The performance hit changes drastically when stepping up to my gaming laptop. (Asus ROG Strix G15 running Bazzite 40 with Ryzen 9 5980HX + Radeon 6800M)
Running Shadow of the Tomb Raider at 1440p with the Highest quality preset, I did two benchmark runs with Game Recording on and off, recording results from the 2nd run to ensure hardware was nice and toasty.
The reduction in performance this time was a whopping 37%!
