Spottywot (1910658) writes "While there were some reports flying around about further delays of the Battlefield 4 Mantle patch it has been delivered on time today by DICE. The necessary AMD Catalyst 14.1 beta drivers — to get Mantle optimisations to work — are yet to be released publically but are expected to be available later today.
Johan Andersson, one of the Technical Directors in the Frostbite team, said about the update: "Battlefield 4 on PC is already quite heavily optimized using DirectX 11 and DirectX 11.1, but with Mantle we are able to go even further: we’ve significantly reduced CPU cost in our rendering, efficiently parallelized it over multiple CPU cores and reduced overhead in many areas." Andersson added 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". DICE did a "couple of benchmarks" using Battlefield 4 on a variety of configurations. 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."

Windows 8 applications hacked already, anyone surprised?
Spottywot (1910658) writes "Earlier in the week a blog post by Nokia engineer (and former Microsoft employee) Justin Angel highlighted a number of issues with applications from the Windows Store that enabled, among other things, the unauthorized conversion of trial apps into full versions, the modification of the prices of in-app purchases, and removal of embedded advertisements. Soon after publishing his post, Angel's blog was knocked offline in a flood of traffic; at the time of writing it remains unavailable, returning 503 error messages instead of content.
The integrity of Windows Store applications is an important issue. It forms part of the value proposition to developers, of the store itself; not only does the store provide easy, reliable billing, distribution, and updating, it also provides at least some degree of protection against piracy and other kinds of exploitation. If Windows 8 can't provide this then competing platforms (such as iOS) and competing delivery mechanisms (such as the Web) become more appealing." Link to Original Source top
Spottywot (1910658) writes "Security specialist Symantec has released an analysis of the cross-platform Jnanabot worm, revealing that around 16 per cent of infections are found on Mac OS X machines.
The figures, which Symantec released earlier this week, analysed the infected machines that made up the Jnanabot botnet in December 2010, and came to a somewhat surprising conclusion
While the vast majority of machines infected by the Java-based Jnanabot worm and forming the botnet were Windows-based, 16 per cent of the network was made up of machines running Apple's Mac OS X — a platform that is often claimed to be immune to malware." Link to Original Source
