DirectX 12 is set to supercharge PC gaming

DirectX 12 is set to supercharge PC gaming!

Microsoft's API is going to make your gaming machine faster

Microsoft has taken the wraps off its latest graphics API and it's all about performance and unifying graphics across all devices. Oh, and two other things: it will be compatible with most recent graphics cards and it makes AMD's Mantle API look a bit pointless. DX12's true potential is untested so perhaps AMD knows something that we don't and that's why it pressed ahead with Mantle. Time will tell. Read more about DirectX 12

First look at the next-gen Batman: Arkham Knight

Batman: Arkham Knight

A thrilling conclusion to an epic series?

With Rocksteady's first two Batman games already a huge success, Batman: Arkham Knight promises to be even bigger and badder than before. A combination of the first game's forensic detective capabilities and the second's caped crusader storyline, Arkham Knight is a healthy dose of both - along with a totally suped up Batmobile and next-gen Gotham City world.

Wear and tear: is the smartwatch trend worn out?

Wear and tear: is the smartwatch trend worn out?

The week in flames!

The unexpected announcement of the Android Wearproject split the internet in half. The half with the nice hair and the deliberately chunky glasses frames were enthusiastic about it, keen to have yet another gadget to spend a few hundred dogecoins on regardless of need. The scruffier half, though, was less impressed. Google's ambition to force us all to speak to our devices to control them is baffling, as (a) it doesn't work very well no matter how hard you try to annunciate like Professor Henry Higgins, and (b) people feel stupid talking to their phones, glasses and - coming soon! - watches.

Virtual reality can "fundamentally change communication"

Virtual reality 'can fundamentally change communication,' says Oculus CEO

So says Oclus CEO who just sold up to Facebook

"It's going to go far beyond just games," Iribe pronounced to TechRadar about Oculus Rift. "We really believe the ultimate application for this is actually social communications. That's where it's long-term going to go." Iribe blurted this out in an almost you-have-to-hear-this manner. He was being ushered off to another meeting, but wanted to impart this final promise in Oculus Rift's potential, and perhaps give a little wink to today's $2 billion revelation.

The amazing new Audi TT is one of the most high tech cars ever made

The amazing new Audi TT is one of the most high tech cars ever made

All the tech all in one vehicle

Audi has just raised the bar for all-round techno-mastery with the new TT coupe. And we've been to Germany to get a hands-on feel for all the new features. Here's a quick taste of what we're talking about. High-res LCD panels, twin quad-core CPUs, 4G data, touch control, natural-language voice recognition, iOS-aping search functionality, intelligent auto-dimming headlights, hybrid aluminium and steel construction, computer-controlled four-wheel drive. And more more, plenty more. Yup, the new TT goes way beyond the 'virtual cockpit' tech that grabbed the headlines when Audi first announced the car, even if that is the show-piece feature. But let's start there anyway.

Bombshell at Panasonic!

Bombshell at Panasonic: 'resolution doesn't matter, it's all about the colour'

It's not about resolution, it's dynamic range and colors that matter

Hold the front page! It's not picture resolution that makes for a great TV image, but old chestnuts dynamic range and colour fidelity. That was the message from TV calibration guru Joel Silver this week when he took to the stage at Panasonic's huge pan-European dealer convention in Amsterdam to support the company's new 4K TV launches.

Jawbone Up24 review

Jawbone Up24

The fitness tracker with the most flair

The Jawbone Up24 is one of the most inspiring fitness wearables that you can latch onto your wrist. It's fashionable, lightweight design makes it easier to wear for a full 24 hours compared to its plain-looking, anchor-like competition. This doesn't feel like you're wearing a single handcuff. Better yet, the accurate activity and sleep tracking metrics make it useful both day and night. Jawbone Up24 review

Pentax K-3 review

Pentax K-3

Will the weatherproof K-3 be enough to tempt consumers away from Nikon and Canon

Since the biggest selling point of this camera is its weatherproofing credentials, it makes sense to buy it with the 18-135mm WR (weather resistant) lens, otherwise it's only the body that can withstand water. This makes it a little more expensive than if you were to buy it with an 18-55mm standard kit lens. Happily, image quality is pretty good in the majority of conditions, and handling is intuitive. While Pentax hasn't done quite enough to drag attention firmly away from Canon and Nikon, it is making moves in the right direction. Pentax K-3 review
