Install steam for Linux. There's enough good games that, unless you are an enthusiast, gaming on Linux only is completely acceptable. I'd recommend Civilization V, dreamfall chapters, spec ops: the line (way smarter than it looks), witcher 2, team fortress 2 and braid. Those are the kinds of games that are officially supported for Steam on Ubuntu these days. Most of the rpg classics (torment, baldur's gate etc) on gog.com also works on linux, if that's more your thing.
Thanks for the tip. Last time I tried steam on Linux it only supported Ubuntu and only has 32bit packages with broken i386 compatibility dependencies but that's probably changed now I'm assuming. I've actually really been enjoying Elite: Dangerous recently and they've just come out with an OSX client which is great.
I run Steam on two different 64 bit Fedora machines (one with AMD, one with nVidia). It might have installed 32 bit compatibility libraries, but I don't mind and didn't notice, if it did.
Civ V and all of the Valve games are excellent under Linux. Rust is a little flaky, but I get the impression it's a little flaky under Windows, too.
Steam on Linux is pretty craptacular overall but it does work on my 64bit Fedora with no additional effort besides installing it. Some games even work better on Linux (e.g. Kerbal Space Program).
You heard something that was true when it was released but which is completely wrong now after many updates. I finished the game from A to Z on Linux and while it still have some crashes it's perfectly playable even on a medium configuration (amd excluded, but that does without saying on Linux right now)
I can't play The Witcher 2, at all. It literally kills my computer, both on Jessie and Sid. After a few seconds in the game my GPU crashes or the kernel panics. It's most likely because of radeonsi.
No, I think they work with the AMD binary blob driver as well, but they have some display/compatibility issues with the drivers on those. You should check the official GIthub trackers for Witcher 2 and Bioshock Infinite, some issues are reported there.
Fair enough it was a little time ago, glad to hear it's better now. However, even though I have been gaming on Linux for years, if playing a high-end title I encounter any performance problems I see no reason not to switch to Windows. You pay for the hardware and the game to have a high-end experience and then you limit that, for what?
Having said all that I have been buying lots of games from GOG and have been really impressed with the quality AND quantity of linux versions.
It's not very good, no, but it works. Many gamers don't really care that much about graphics settings and if you do then Linux gaming is not for you anyway. The graphics drivers and the game executables are more optimized on windows, and that's just the current state of the world.
