Multi-Display Gaming Artifacts Shown With AMD, 4K Affected Too 148

Vigile writes "Multi-display gaming has really found a niche in the world of high-end PC gaming, starting when AMD released Eyefinity in 2009 in three-panel configurations. AMD expanded out to six-screen options in 2010 and NVIDIA followed shortly thereafter with a similar multi-screen solution called Surround. Over the last 12 months or so, GPU performance testing has gone through a sort of revolution as the move from software measurement to hardware capture measurement has taken hold. PC Perspective has done testing with this new technology on AMD Eyefinity and NVIDIA Surround configurations at 5760x1080 resolution and found there were some substantial anomalies in the AMD captures. The AMD cards exhibited dropped frames, interleaved frames (jumping back and forth between buffers) and even stepped, non-horizontal vertical sync tearing. The result is a much lower observed frame rate than software like FRAPS would indicate and these problems will also be found when using the current top-end, dual-head 4K PC displays since they emulate Eyefinity and Surround for setup."

Doubleclick Cofounder Responds to Patent Troll by Filing Extortion Lawsuit 225

New submitter kintamanimatt writes with news that someone other than newegg is fighting back against patent trolls, despite the business case for settling. This time, however, one of the founders of the Doubleclick ad network has decided to use his personal money to not only fight a patent troll attacking his new startup, but to strike back at them under the RICO act. "'There's a lot of outrageous stories, but everyone's so damn afraid of coming forward — It's like going against the Mafia,' he [Kevin O'Connor] said. But the idea that trolls may retaliate against those who speak out is overblown, he thinks. 'If they want to try to teach me a lesson, go for it. This will be my retirement. I'll fight them.' The patent troll's attorney also made the claim that calling someone a 'patent troll' was actually a 'hate crime' under 'Ninth Circuit precedent' and threatened to file criminal charges — unless they settled the civil case immediately, apologized, and gave financial compensation to the troll. The offer was 'good until close of business that day.'"
