SteamOS, the ChromeOS for games.

I really don't understand why they used 2560x1600 as a resolution to test because this is a console after all running on a home TV. As far as I know that resolution is not common for LED TV's so why test with it? Makes more sense to me to use 1080P because this is the standard for TV's and will be for at least another 10 years...

2560x1600 is 16:10 whereas 1080p is 16:9. While there is a difference, it's still fairly close. Atleast it wasn't 800x600 or something with rather crap quality.

What no one has pointed out is the fact that SteamOS does NOT support DirectX API. This means games will not look as good, nor be optimized when running specific hardware. OpenGL is okay, but DirectX is better for all the newer games designed to use it. Frame rates are misleading if what you really want is for a game to look good AND be playable. Food for thought before you go jumping onto the SteamOS bandwagon...

Yes, it does. Stop with the FUD. Even if it didn't, it wouldn't matter because game devs don't even support most of the higher end DX features for years after they release.

It may not look as good as what gaming on Windows looks like, but Consoles run the equivalent of OpenGL, and OpenGL is what Linux supports fairly well.

You have no clue what you're talking about.

OGL has caught up with the feature set of D3D in the past few years, and all they really have to do is adjust the API calls. There are no "hardware specific optimizations" in play here (the last which died off with GeForce FX). D3D and OGL for all intents and purposes produce the same result. The only factor are the drivers, which NVIDIA has maintained excellent OGL support (as far as I know)

Either way, look at the PS4 vs. Xbox One. You can hardly tell any difference between them, and it's basically FreeBSD w/ OGL vs NT6 w/ D3D. And so far developers just use the PS4's extra power to run games at 1080p.

Which developers? DICE isn't running Battlefield 4 at 1920*1080 on the PS4.

The Heaven 4.0 GPU benchmark consistently gives me significantly lower scores in OpenGL versus DX. The only "good thing" that I can attribute to OpenGL is that it has greater backwards compatibility as there are some old DX games that do not run on modern hardware well with DX but run rather well with OGL. Tribes 2 would be an example.

It's either 1080p or 900p. Either way the point is they're using the extra horsepower to render it at a higher resolution than the Xbox One.

And OGL performance depends entirely on the drivers, which historically hasn't been well for Radeon cards. I'm also skeptical that a cross OS benchmark using the same program with the same API isn't apples to apples. Remember when Valve was showing off that Source under Linux and OGL ran appreciably better than Windows with DirectX? It gets you close, but there are still too many variables about the OS (and particularly its drivers) that any cross OS benchmark is pointless.

900p is crap. That's only 1600*900, or 69% of 1920*1080.

Are there examples of a PS4 version of a game running at a higher resolution than the Xbone's?

BF4 and CoD Ghosts, to start.

But this is going off track. The point is OGL and D3D produce the same quality and have the same feature set and for all intents and purposes perform the same. While you can claim on Windows OGL sucks compared to D3D, go look at some examples from the PS3 and 360. Mirrors Edge looked better on the PS3. FFXIII looked better on the PS3. If you go to lensoftruth.com, you'll find their earlier articles pointed at the 360 was better in quality (if on a scrutinizing level) with a few PS3 wins, but over time both of them pretty much started having the same quality.

OpenGL support in many modern titles is an afterthought, and thus not often given a high priority. Heaven was primarily written to showcase the power and awesomeness of DX---it's not too surprising that it works better on the other side.

Wait for objective benchmarks, like the ones Phoronix is likely to release soon, although you can also look up results for Portal 2 across Mac, Windows, and Linux platforms, as about the least biased possible result to my knowledge.

avatar

Portal 2 isn't exactly relevant: ancient gaming engine optimized for the consoles. Valve is living in the past with Source. MPC itself points out the irony of Valve's particle test, designed to showcase multicore technology, failing to scale to more than 4 cores even to this day.

...I'm also not willing to accept that a Valve game is unbiased regarding the Valve platform.

How does that compare to the cards' performance in Windows?
