Hi. I notice that V17 pro can't play movies from FS7 smooth as V16. File is mxf 1920x1080 422 50p and framerate in vegas is 25-35. This same files played in V16 has beatiful 50fps. On events I have only Color Correction and Curves, nothing special.
Both show about 60% CPU, but V16 20% GPU, while V17 only 10%. I view on "preview (full)" in 1920x1080 on second display.
Hardware I/O on, Video->GPU acc. on, Preview Device->Optimize GPU on. Is there anything more to setup?
