BillyMaysFan59: Hmmmm, maybe it's nVidia Optimus that people have had problems with.

Maighstir: Switchable graphics is still a thorn in the side for Linux graphics, yes.
It was already hard enough trying to figure out how to get my switchable AMD/Intel graphics setup working under Linux using the open source drivers. Finally learned how to use PRIME to switch on the discrete GPU for games that need more graphical power. (there's even good documentation on that in the ArchWiki)

Maighstir: The new AMDGPU driver will be officially released with kernel 4.2. It's already available in source, so if you're up to building the kernel by yourself, you can already get it up and running. You'll need an R9 285 or an Rx 3xx series card though, which haven't been usable under Linux yet (the fglrx driver didn't support them, nor did the open-source radeon, and amdgpu doesn't yet support any older cards though I think it will eventually gain support for all GCN-based cards).
Ah I see thanks. My card is a R9 270x so it's not new enough, and building the kernel isn't something I want to mess with right now anyway. :D

The open source driver i'm current using is great anyway. I can do my web development, then play some Hearthstone and any other game i've tried so far without rebooting. Pretty much the only time I need to be in Windows now is if I want to play Witcher 3.

I just shut off the AMD chip through BIOS, only switching it on (disabling the Intel) when I want to do something the Intel chip is unlikely to handle well. I don't really use my laptop for gaming so the Intel is usually enough, and with a Radeon 3650 (I think) it isn't going to win many benchmarks anyway.

HD 3650 on mine, I think. Heh, it provides enough graphical power for me, since I mostly play older (or simpler) games.

For example KotOR runs fine, Mount & Blade Warband (using DirectX 7 instead of 9) at high settings works just about flawlessly, and Terraria is smooth as butter. Deus Ex (no New Vision or HDTP mods, just Kentie's launcher) at maximum resolution is great too.
