Windows 8 - Improved Multimedia Performance , Less Power Usage, HD Video Chat
The release of Windows 8 may have a lot to do with its new user interface, and touch-screen optimization for tablets , but Windows 8 will also offer improved multimedia performance along with more efficient and reduced utilization of system resource , claims group program manager Scott Manchester, in a post on MSDN blog .
The post gives detailed information how the multimedia platform on Windows 8 delivers multimedia performance with much lesser CPU utilization . For example, WMV decoding required 32% CPU utilization in Windows 7, but in Windows 8 it was cut to just 14%.
“With Windows 8 running on a Windows 8 certified PC, video decoding for common media formats will be offloaded to a dedicated hardware subsystem for media. This allows us to significantly lower CPU usage, resulting in smoother video playback and a longer battery life, as the dedicated media hardware is much more efficient than the CPU at media decoding.â€
Another improvement that the post mentions is in communication . When you communicate with another person, you expect near-instant responses. The latency was addressed in windows 8 by switching to low-latency mode when PC is used for communication . It will also switch to playback mode which will use buffering to protect against glitches caused by processing spikes or network traffic, and to reduce power consumption.
“In playback mode, the average latency of the pipeline is about 575ms. This delay is necessary for a smooth playback experience when consuming video, but unacceptable for real-time video communication. In low latency mode, on the other hand, the measured latency is well under the target goal at each of the measured video resolutions,†says Steven Sinofsky, the team’s blog poster.
Another improvement in Windows 8 is support for HD video calling . New class drivers will work transparently with applications to provide support for HD video features.
