I've also got a new i7-4770k with a GTX 780Ti card, all 540MB/s SSDs and an ASUS Z87 mobo with Thunderbolt 2 (20Gbps) ports. I can watch the full screen preview at actual speed on a second monitor in Full HD - but
ONLY if there are no effects or transitions. As soon as there's any extra rendering work, I get the choppy playback.
The whole point of spending almost $3k on a dedicated machine was to improve my editing experience, but so far I'm not happy
I started with a Quadro K4000, but that card was slower than the GTX 770 card I had in my i5 3570K rig despite being more than 2x the price. I returned the Quadro and got the 780Ti, and while the gaming benchmarks are through the roof I only see about a 10% improvement in rendering/producing times.
FWIW, I work with 1920x1080/60p/28Mbps .mts from a Canon HF G30 camcorder. I put together 5 of those clips with 4 simple fade crossover transitions. My test video has a play length of 3m56s. With my CPU overclocked to 4.3GHz and using the brand new nVidia 334.89 WHQL drivers, the time to produce H.264 AVC 1920x1080/60p/28Mbps .m2ts video is as follows:
Hardware Acceleration: Enable hardware decoding = ON,
Enable Open CL = OFF; Fast Video Rendering: Using Hardware video encoder, NO preview:
2m22s or 1.66x actual speed
Same hardware settings but with
Enable Open CL = ON, using Hardware video encoder:
2m38s or 1.49x actual speed (11% SLOWER than with CL turned OFF!)
Same hardware settings and
Enable Open CL = OFF, using SVRT:
3m37sor 1.08x actual speed (53% SLOWER than GPU)
Same hardware settings and
Enable Open CL = ON, using SVRT:
4m04s or 0.88x actual speed (88% SLOWER than GPU)
Basically, it looks like using Open CL slows every down every rendering combination and should NOT be checked! Maybe there are benefits on older or slower cards, but it's definitely a drag on my system.
BTW, Win 8/8.1
does have the Windows Experience built in, you just need to access it via
Power Shell. My system is rated as follows: CPU = 8.5; Direct 3D = 8.8, SSDs = 8.1 (the weak link!); Graphics = 8.8; Memory = 8.5.
I realize that anything involving 60p and/or 2k or 4k resolution takes a ton of horsepower, and I was hoping to se a big performance increase moving from an Ivy Bridge to Haswell with AVX2 and hyper-threading. But if this setup can barely keep up with full HD previewing on bare clips only, how will any of us be able to do real editing in real time?
