As a visual showcase of what a remaster meets remake can be, as a re-release of sorts, and as a reminder that classic design and pacing will always be just that, Portal with RTX is a triumph.

When Valve began to talk up its shift towards hardware and its own line of Linux and OpenGL powered line of Steam Machines a few years back, the general consensus was that these machines would be optimised purely for gaming. And they probably are. But, according to a recent performance analysis at Ars Tehnica, cross-platform games, those developed for both Windows and SteamOS, can see a frame rate discrepancy of up to 58 percent.

Now benchmarks and tests do vary across different types of hardware, software, operating systems, and drivers. So the testing environments themselves can often influence the outcome. These benchmarks for SteamOS though are very interesting as they represent titles like Middle-Earth: Shadow of Mordor and Metro: Last Light Redux, two titles developed for Windows (utilising DirectX technology) that were then ported to Linux (SteamOS) and OpenGL. Which means the end results may lie with the fact that these were ports, and that developers for graphically intensive 3D games are by now more used to DirectX.

But! In terms of Valve's own library of games, including Team Fortress 2, DOTA 2, and Left 4 Dead 2, only the latter displayed similar performance to its Windows counterpart. With the other titles again showing noticeable performance hits. Which does feel like it should be the other way around.

This could all change when Vulkan, the next generation of the OpenGL, hits. As it's built on a similar foundation to that of DirectX 12.

Check out the full analysis here.

Gonna file this as another win for:

I mean seriously, who'd have thought a company with billions in their war chest for development, in addition to the support of the largest chipset manufacturers on both sides, having been in development for what, 15 years now, would be able to spend more time, money and man-hours on getting better performance for the Windows platform than a new up-and-coming platform that is more or less funded by anti-capitalist "I want everything free and open" types? :/

That's not why Valve made SteamOS, it was for insurance against Microsoft trying to build a windows software store which replicated Steam and took their sales. They wanted to make games less reliant on Windows.

bit of an unnecessarily obnoxious post Raven

I think the idea for SteamOS came from Newells' vision at the time of Windows 8 and beyond being less accessible for PC gaming, and his apparent dislike of developing for any of the consoles available

But Gabe f*****g loves developing for consoles if you fill his office with bags of money, just look at Portal 2 and the PS3.
