Spent the weekend playing various intensive Steam games on my Framework Laptop 16 - dGPU switching just magically happens when you launch a game - no DRI_PRIME needed on Framework Laptop AMD images of Bazzite. And they're just getting warmed up. https://bazzite.gg
Also, on my Framework Laptop 13 running Bluefin - look to the upper left corner at the launcher. Yeah, and Bluefin is just warming up.
