Submission + - Nvidia's Maxwell architecture performs poorly at DirectX 12 games

edxwelch writes: Benchmarks have shown Oxide Game's Ashes of the Singularity’s DirectX 12 Alpha benchmark performing better on AMD GPUs. There has been much discussion about the cause, but recent comments on Overclock forums from an Oxide Games developer reveal that Maxwell GPUs do not properly support Asynchronous compute and that's why AMD performs so well in the benchmarks.
The problem seems to be hardware related. The Maxwell architecture is optimised for the serial nature of DirectX 11, while AMD's GCN GPUs have been built from the ground up to take advantage of asychronous shaders.

Comment Not really for consumers (Score 1) 80

These drives are 7 time faster than the fastest SSD, but also more expensive. That should be the other way around to be beneficial to PC users.
SSDs are currently too expensive to use as bulk storage, so normally you have a small SSD, which has the OS and other frequently accessed files and then you have a HDD which holds less used large files (i.e. video library etc.)
The HDD is an order of magnitude slower that the SSD, so this is really what is slowing down the system. This 3D XCross drive is making the part of the system that is already fast, faster.

Comment The end of DirectX? (Score 2) 46

I'm quite amazed that Vulkan will support all versions of Windows from XP onwards. So you can have the low overhead of DirectX 12 without forcing your users to upgrade to Windows 10.
I can see a lot of game developers migrating to Vulkan, just because they get more sales the more OS versions they support

Comment The reason why it appears fast (Score 1) 405

If you install Windows from scratch on a PC it will always run faster than the previous version (especially if it's being running for 7 years, as in this case). The reason is because the way Windows works. Certain system files (user profile, registery, etc, etc) continuously get bigger and bigger, so as you use it for several years the system gets slower and slower. Installing a fresh version of Windows (regardless of which version) starts everything from scratch and makes it run a whole lot faster.

Comment Re:Pu-238 was available when it launced (Score 2) 419

Here's what Wikipedia says about it:
"The United States stopped producing bulk plutonium-238 in 1988;[5] since 1993, all of the plutonium-238 used in American spacecraft has been purchased from Russia. In total, 16.5 kilograms have been purchased but Russia is no longer producing plutonium-238 and their own supply is reportedly running low"
In fact, the Horizons project only got their supply by salvaging a spare from the Cassini mission.

Comment Not nuclear fear (Score 5, Informative) 419

Firstly, what caused the problem was not "Nuclear fear", but failure of the harpoon to hold Philea down. The solar panels would have worked fine otherwise.
Secoundly, Plutonium-238 is simply no longer available - nobody makes it anymore. The reason why is because it is created using a dangerous and expensive process by irradiation of neptunium-237.

Submission + - Intel Layoffs Coming?

cleara writes: According to an Oregonian article (http://www.oregonlive.com/silicon-forest/index.ssf/2015/06/intels_layoff_letter_we_have_m.html) that is so-far not paywalled; Intel is planning a currently unknown number of layoffs company-wide. The article does have a redacted copy of the layoff letter going to affected employees
