Thanks for sharing :)
Both of the projects I use include 4x 30 second clips each, based on whether or not the scenes are light and dark. The tests are straight 4K/60 to 4K/60 encodes, with no use of filters. I do have plans to introduce filters into the testing at some point, and in fact have the scripts for it already, but with AMD performing so poorly, I feel like it might be best to wait for something to change. AMD performed a lot better in VP15.
If it takes too long, I'll just do that testing with both vendors and be done with it... because it is what it is. The other four encodes I have to use in future testing include Dark/AutoLooks, Dark/Median, Light/LUT, and Light/Upscale - all four seem to use the GPU quite well. But it'd be nice for AMD's cards to work as we'd expect them to. The ProRender result even baffles AMD, but the reviewer's guide included performance for that with ONLY the Radeons, with the NVIDIA spots left empty. I feel like that had to have been on purpose.
I am really hoping a driver update will help this, but since the weak performance occurred in the WX 8200 review as well, I am not too hopeful on that coming soon. It could also be a Vegas thing, though.
When the time comes to do more testing, I might have to load up VP15 again just to sanity check things.
