Quoting: XaeroVincentWell I mean more like a ball park figure... is it like 10 or 20 FPS slower across the board or even more? Mainly curious about an ballpark figure across any game from your testing.

Quoting: XaeroVincentdubigrasu, how much performance is lost between SteamOS 1.0 and 2.0? How many FPS?

Do you think the brand new NVIDIA 358.13 driver might make any difference?

Quoting: MblackwellI wonder what the difference is if you run Nvidia driver 355.11, since that's what's recommended in the README.

Quoting: mr-eggwhat about settings ? Sure people may not like to have to drop AA, but linux is behind in Multi sampling Antialiasing at the moment. Does it use it on this test ? If so then doing the test without may not be popular ( because people want the same quality across the board ) but it would at least identify how much of that 30% difference was down to a specific game setting.

Still, running 1080p 60fps with better than console graphics is entirely possible even with a 30% loss on a decent PC / Steam machine.

Quoting: nattydreadis it a native build or a port?

It was ported by Feral Interactive, and it is native. A port doesn't make something not native.

well what I mean perhaps is: does it use a wrapper to DirectX or does it directly use OpenGL? There must be some reason it doesn't perform as well on SteamOS.

Directx wrappers are obviously always less performant under linux, and opengl is also slower under linux than windows.

Quoting: aristoriasWhat GPUs, what driver, why Ubuntu for AMD and why SteamOS for nVidia.
Whoever did this should be ashamed that these questions rise and stay unanswered.
What a pointless waste of time and effort.

Quoting: dubigrasuThere is a FPS counter included, but for whatever reason still hidden and it takes some minor tweaking to activate it (min 1:10):

HOW did you make the FPS counter appear? :P

Wow, that's a huge hassle, and the average Steam Machine user is not going to want to do that (and they shouldn't have to). I don't understand why Big Picture / SteamOS modes can't just have a simple toggle via the in-game overlay.
