If your system is not supported, the option will be disabled. -Performance --------------- -Take note that only the encode portion of the encode pipeline is done on the AMD hardware. -Every stage prior and after in the pipeline including (decoding, filters, a/v sync, muxing etc.) all happen on the CPU. As a result, it is normal to have high, or 100% CPU utilisation during encodes. +## Performance -It is common, particularly on lower end hardware that the CPU may be a bottleneck for the encoder. To minimise this effect, turn off any filters that you do not require. +Only video encoding is performed by the hardware encoder.
