SimpleEncode sample runs very slow on Radeon R9 200 Series

Hello,

Recently I downloaded this Media SDK 1.1 Beta and compiled SimpleEncode sample on one of my computer with AMD Radeon R9 200 Series (Driver 14.501.1003.0) and AMD A10-6700 APU with Radeon HD Graphics

I let it convert a yuv file to h264, with -c exampleConfigLowLatency.cfg, and it was slow like hell.

I traced its progress, it was about 1~2 frames/second, which was about 50 times slower than normal (another sample on intel/Nvidia machine using their sdk with same input file)

 

the CPU was about 30% busy, and GPU was very little used.

 

Is the SDK not support this series of video card yet, or I have to change some value in config file?

Any information will be helpful.

 

Thanks
