Quoting: nattydreadWhy is openGL slower under linux than windows?
I'm surprised by that!

Thanks for all the answers!

It's not, but the game-specific optimisations that are in the Windows driver are not enabled in the Linux driver.
Apart from that, depending on how the game is written, the performance will differ between Linux and Windows, sometimes better on Linux, sometimes better on Windows. Here are some recent test results as an example. [External Link]

The one thing that made me really chuckle, was talk about performance. According to the Alienware rep there's no performance "degradation" on SteamOS. We all know most ports perform worse than they do on Windows, so it's marketing speak at its finest. Again, Vulkan is going to certainly help, as will Alienware/Valve and others talking directly to Nvidia/AMD/Intel to improve their drivers for OpenGL too.

To be fair, he does seem to mean performance degradation at the driver level, which seems correct.

Quoting: PublicNuisance[...]I can't find anywhere on their homepage, trailer or facebook page where they mention Linux though.[...]

It doesn't seem to be anywhere on their site, their Facebook page or their Google+ profile, but it's on the description page on Ulule [External Link].

Quoting: neowiz73I still don't understand what made them have to lose the Linux symbol. their game seemed no different than many other ports. Nevertheless, it has always worked great for me on multiple distributions.

If it didn't launch correctly on SteamOS, the icon will be removed by Valve.

Trine 3 has their icon though, strangely enough, since they use a launcher and their menus don't work with a gamepad (nor a pen tablet, so I'm out of luck); the only reason I can play it is my Steam Controller (which defaults to gamepad mode for Trine 3, so it doesn't work "out of the box" ).

Quoting: StarbellyIn future surveys can you please ask about audio setups? (Headphones, Stereo Speakers, 4-channel, 5.1, 7.1)? I have noticed that surround support is very inconsistent among ports to linux, [...]

I'm so with you on this one!! I researched and bought a very nice set of surround headphones specifically in anticipation of playing Metro 2033 and Half-Life 2 only to find that neither actually supported it, making them mostly useless for what I bought them for.
They do work great for video though, but that's besides the point (they're the Roccat Kave XTD; I recommend them wholeheartedly).

What's the best place to send in tips? I sent in this tip last Wednesday on Facebook [External Link], but it seems it slipped through the cracks?

Woohoo! It arriving at the same date as my The Art of Alien: Isolation book is perfect! :D

Was that "jump platforming for the blind" I just saw? ...I'm going to need a positive review before getting this one :/

Quoting: CybolicIt does. It's worked for me perfectly in Ubuntu 15.04, Kubuntu 15.04 and SteamOS. It's completely different from a normal gamepad rumble though, much closer to what you get while typing on an Android phone's keyboard. It is quite light though, so can be missed in the heat of a game, but I've at least grown somewhat used to its feedback, enough to know which emulated button I'm on most of the time.

OK, thanks! I guess I was just expecting more, since some people claim that in trackball mode they can feel the ball spinning.

Oh I definitely can as well! It's only in very hectic game moments that I don't notice they haptics, so that's likely just lack of focus. But rumble, it is not.

Quoting: ElectricPrismI never backed it as the video felt like it was comprised of "management" and lacking the technical & artistic passion I would expect for a group wishing to carry on such an amazing legacy.

Now that's the in EA thought, I gotta say it looks like it may "turn heads" - if they develop 4 player co-op and full stream controller support and it looks fun then that'll sell me.

I'm collecting a game aerosol for 4 player Steam Machine LANing, this would make a nice feather in my cap.

Steam Controller support is coming [External Link] at least :D
