PSA: Flatpak likes to mess with GPU drivers. If you experience terrible performance with Flatpak Heroic, try this (lemmy.world)

Disclaimer: Someone in the comments pointed out that this affects Nvidia only. I don't have AMD, so I can't verify if that's correct, but likely this is only for fellow sufferers of the Green Nightmare.

I had this issue for months. Randomly, the performance for games would be abysmal (I'm talking 5 FPS in 10yo indie 3D titles). Then it would randomly work again for a few days or weeks until it would become terrible again.

Turns out, the reason for that was that flatpak appears to cause trouble when the system GPU driver is updated, but flatpak update isn't run. So when I did dnf update (and it updated the Nvidia driver) without running flatpak update afterwards, the performance would suck, until something (or I) ran flatpak update again.

So if the performance in games launched through a flatpak version of a launcher like heroic sucks, run flatpak update.

And if that doesn't work, run

flatpak install flathub org.freedesktop.Platform.GL.nvidia-575-64-05 org.freedesktop.Platform.GL32.nvidia-575-64-05

(Replace the version with your Nvidia driver version, and in case of AMD, google whatever the appropriate way is to install the drivers for flatpak.)

Sadly, there's close to no AMD dGPU laptops, at least in my area. And the 3 or so models that exist are wildly more expensive...

Part of the reason for that is because their iGPUs are actually worth gaming on, see: Steam Deck and both the PS5 and Xbox Series consoles.

It's so-so, tbh.

I looked up the best AMD iGPU, and that seems to be the Radeon 8060S. That one is, from what I can see, about on par with the 4070 laptop. In gaming, it's a bit worse. In other workloads, it's a bit better.

But the cheapest laptop I can find with an 8060S is some HP Zbook Ultra G1a for €2800. I got my Lenovo LOQ with a 4070 for €900.

AMD has learned that laptop gamers don't give a shit about anything that's not Nvidia. Their dGPU laptop solutions were never desirable for the general market, so they've instead started focussing a lot more on stronger APUs.
