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.

Well, Interstellar Marines is the first game where I noticed this. The difference in FPS is 10 at most but stutters like crazy.
Dying Light has more or less the same FPS but is too choppy to play.

Thanks for the info. Hmm. Have you by chance tried these games on other modern distributions? Could it be the more modern Linux OS stack (compared to SteamOS 1.0) causing problems? I wonder how games would perform doing a SteamOS 1.0 vs 2.0 vs Ubuntu 15.10 vs Archlinux / Antergos benchmark with all the same latest Nvidia drivers.

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

I haven't tested Alien Isolation with SteamOS 2.0 if that's what you're asking.
But 2.0 has a constant loss in performance with other games I tried, so I just stopped using it.

It's quite upsetting to see the flagship 2.0 being worse than 1.0, especially since Valve discontinued 1.0. Valve needs to kick it into overdrive and get serious here if they intend to keep this going. I know it's not reasonable to expect all games to run as good as Windows but things can certainly improve if they've gotten worse than before! I hope you decide to show Valve benchmark results between 1.0 and 2.0 soon.

Seems pretty unlikely:

9. Linux & Mac support
We are not planning to support Linux and Mac for now.

That said, JC3 would still be playable on Linux via a Windows guest in KVM/Xen w/ GPU passthrough or a cloud game streaming service, such as LiquidSky or Amazon EC2 w/ ec2gaming AMI + Steam In-Home Streaming + VPN.

How does VP's eON compare with Feral's IndirectX library wrapper used in most (or all?) Feral ports?

From my understanding, eON is a compile-time wrapper / translation layer just like Feral's IndirectX and Valve's ToGL.
