Viewsonic projectors: now powered by lasers

Viewsonic has been busy showing off its latest display tech in London today, the highlight of which is a large black box that brings together two technologies which will always be close to PC Gamer's heart: projectors and lasers.

The new Pro 9000 is a 1920x1080 affair capable of creating an ad hoc display up to 150 inches in size, but instead of a hot, power hungry and ultimately short lived incandescent light bulb inside, it uses a combination of lasers and LEDs to produce a 1600 lumen beam.

Your next home network might feature lasers

Trying to work out whether ethernet, powerlines or wireless is the way forward for reducing your ping time? They're so old fashioned you might as well be playing by mail. In the not too distant future we're going to be gaming by laser.

Or at least, we will if Researchers at Taiwan's National Taipei University of Technology have their way. They've been working on ways to connect PC to router using lasers, and have discovered that they can create faster-than-WiFi optical links using the kinds of laser pointers you get free in a Christmas cracker.


Portal 2 review

PC Gamer at

I may be the dumbest genius ever. At least, that’s how I feel after playing Portal 2’s fantastic single-player campaign. Many puzzles in the last third of the eight to 10 hours (perhaps less, depending on how clever you are) of its brain-bending puzzle “test chambers” had me convinced at one point or another that they were completely unsolvable, and that some bug or sadist game designer placed the exit just out of reach. I’d let out exasperated sighs as every attempt met with a dead end. I’d grimace in disapproval as I plummeted to my death for the tenth time. I’d consider surrender.

Then, through either sudden revelation, divine inspiration, or total accident, it would come to me: use the orange Propulsion Gel to reach the energy bridge, then catapult across the chasm and shift my blue portal to the inclined surface (in mid-air, mind you) to launch me up to the ledge, grab the refraction cube and redirect the laser beam to wipe out the turrets and activate the switch! It’s so simple, I can’t believe I didn’t see it until now. One half of Portal 2’s brilliance is making me kick myself for not thinking of the impossible; the other is making me feel immensely satisfied with myself when I finally do, again and again.

Note: while we've made every effort to avoid spoilers in this review, you cannot review a game without discussing what it does well and what it doesn't. Be aware that reading any review is going to take some of the surprise out of it.
