GPU Decoding Specifications
In V8.5, support for GPU (Graphics Processing Unit) decoding is added to lower the CPU loading and
to increase the total frame rate supported by a GV-System. GPU decoding only supports the following
software and hardware specifications:

Note: To apply GPU decoding, the recommended memory (RAM) requirements is 8 GB or more for
64-bit OS and 3 GB for 32-bit OS.
Hardware Specifications
Motherboard Sandy Bridge chipset with onboard VGA (external VGA cannot be installed)
Ex: Intel® Q67, H67, H61, Q65, B65, Z68 Express Chipset.
Multi-Channel Playback Specifications
In V8.5, multi-channel playback in ViewLog has been enhanced to improve the smoothness of the
video by producing higher frame rate. However, playing back multiple channels at high resolution can
increase the CPU loading especially if the GV-System is processing other tasks simultaneously. As a
result of the high CPU loading, dropped frames may sometimes occur in recorded video when playing
back multiple megapixel channels.
To avoid the problem, it is recommended to play back megapixel video in single view.
