I realize this Thread is a few months old now, but I have the exact issue with an
AMD GPU and was wondering if anyone knows of similar workarounds/issues with those (most here were talking about
NVIDIA GPUs).
I have an AMD R9 280 3GB and VSPx8 doesn't work too slowly, it seems ok, but playback in the Preview Window becomes pixellated and choppy/laggy when playing back the Timeline in
Project mode.
Edit:
And it is VERY SLOW IN RENDERING... a three-minute Project took 8 hours to render (when using NewBlue Titler text elements, it did not take that long with 'regular' Text added)
I have Enabled all of the Hardware Acceleration options in the Preferences and did not see an increase in Performance or Playback, although I did get the "HD" button/icon appearing after that, below the Preview window (this pixellation and choppyness does not occur when in Clip mode). I even tried to Enable the Smart Proxy function, but it did not make any difference.
Project Properties are the same as the video material: 1920x1080 MJPEG with PCM audio.
This is with a brand-newly purchased and installed VSPx8, happy to be an owner of this great software otherwise
(As a comparison, I find that PowerDirector seems to take advantage of the GPU quite well and has no such problems with Playback of the Preview, it comes through as Full HD, crisp and fast, even with multiple effects and overlays; although I would like to use VSP for some of the Features it has over PowerDirector ...sorry to name a competitor.)
Just wondering if anyone has encountered this or has any ideas for AMD GPU owners. Thanks
