I did some performance testing using Sony Benchmark project. This test I am using VP15.
My old system is Windows 10 Pro , I7 4930K 6 cores @4.5ghz 64GB DDR3 1866mhz R9 290X video card.
Render to Magix MP4 1080 30P take 1:35s GPU/CPU usage 70/100%
Render to Sony AVC MP4 1.02s GPU/CPU usage 79/83%
My new system is Windows 10 Pro, AMD 1950X 16 cores @ 4ghz 32GB DDR4 3200mhz, Vega 10 Frontier Edition video card. VP15 is not support my new card yet. I am rendering using CPU only and this monster beat the times for GPU/CPU combination.
Rendering to Magix MP4/Sony AVC both are under 60s. Needless to say, I am happily dig it. I just hoping future Vegas pro released will support my new video card. This will be even better.
