MojoKid writes "AMD has a new set of drivers coming in a couple of days that are poised to resolve a number of longstanding issues and enable a handful of new features as well, most notably support for Mantle. AMD's new Catalyst 14.1 beta driver is going to be the first publicly available driver from AMD that will support Mantle, AMD's "close to the metal" API that will let developers wring additional performance from GCN-based GPUs. However, the new drivers will also add support for the HSA-related features introduced with the recently released Kaveri APU, and will reportedly fix the frame pacing issues associated with Radeon HD 7000 series CrossFire configurations. A patch for Battlefield 4 is due to arrive soon as well and AMD is claiming performance gains in excess of 40 percent in CPU limited scenarios but smaller gains in GPU-limited conditions, with average gains of 11 — 13 percent over all."
First time accepted submitter Spottywot adds some details about the Battlefield 4
improvements, writing that Johan Andersson, one of the Technical Directors in the Frostbite team, says that the best performance gains are observed when a game is bottlenecked by the CPU, "which can be quite common even on high-end machines." "With an AMD A10-7850K 'Kaveri' APU Mantle provides a 14 per cent improvement, on a system with an AMD FX-8350 and Radeon 7970 Mantle provides a 25 per cent boost, while on an Intel Core i7-3970x Extreme system with 2x AMD Radeon R9 290x cards a huge 58 per cent performance increase was observed."Read Replies (0)

An anonymous reader writes "Nearly 85 years after pioneering theoretical physicist Paul Dirac predicted the possibility of their existence, an international collaboration led by Amherst College Physics Professor David S. Hall '91 and Aalto University (Finland) Academy Research Fellow Mikko Möttönen has created, identified and photographed synthetic magnetic monopoles in Hall's laboratory on the Amherst campus. The groundbreaking accomplishment paves the way for the detection of the particles in nature, which would be a revolutionary development comparable to the discovery of the electron."
That's quite a step beyond detecting monopoles

Hugh Pickens DOT Com writes "Kim Severson reports at the NYT that by keeping schools and government offices open, and by not requiring tractor-trailers to use chains or stay out of the city's core, metropolitan Atlanta gambled and lost. "We don't want to be accused of crying wolf," said Gov. Nathan Deal, who pointed out that the storm had been forecast to just brush the south side of the city. If the city had been closed and the storm had been as light as some forecasters had told him it was going to be, he said, money would have been lost, and people would have complained. Tuesday's snowfall, that brought only 2-3 inches of snow to most of the Atlanta metro area, and the hundreds of thousands of motorists who flooded the metropolitan area's roadways as the storm moved in — created travel nightmares for commuters, truckers, students and their families. Some commuters were stuck in their vehicles up to 18 hours after they first hit the roads. Others abandoned their cars in or beside the road. Hundreds of students spent the night at school. Some surrounding cities, including Hiram, Woodstock, Sandy Springs and Acworth, opened emergency shelters for stranded motorists. "It's an easy joke made by Northerners," wrote Joe Sterling and Sarah Aarthun. "A dusting of snow shuts down an entire city and hapless drivers white-knuckle their way through a handful of flurries." Further North streets are salted well in advance of a coming storm but Atlanta doesn't have the capacity for that kind of treatment. "We simply have never purchased the amount of equipment necessary," said meteorologist Chad Myers adding Atlanta had plenty of warning. "Why would you in a city that gets one snow event every three years? Why would you buy 500 snowplows and salt trucks and have them sit around for 1,000 days, waiting for the next event?""Read Replies (0)
