Hi,
Can you share more details on your environmental setup? Guest OS and Client OS? MMR will not work with flash video, so it is only host side rendering of PCoIP.
1) For VADC, you mention that it disturbs flash video. Does the choppy video occur on all flash videos (low resolution and 1080p)? Or just the higher resolution videos?
2) For video performance, software based GPU isn't going to help with video playback. The PCoIP default settings have not changed. What was the video format that you tested with?
Thanks
