Vegas Pro 11 GPU Accel Slower then VP10 No GPU

Guess ya need some system specs:
i7-3930K @ 4.5
2 XFX Radeon 6970 CF
Catalyst 12.2 Drivers & system is upto date as well.

Well coming from SVP10 I used the Sony AVC 720p 16mb template. Which I can encode my Fraps Full 1080p 60fps very quickly ex: 15min vid takes 10min to encode.

Yet on SVP11 with GPU accelleration enabled it greatly increases my time, however if I disable it then I gain about 2mins on my render using virtually the same settings since it was at least able to import it from vegas pro 10.

So I'm not real happy that it takes longer with the gpu but yet it's a bit fast with only my cpu. Thats really my only gripe at the moment other then that I am enjoying this new version.


Just to show what I'm talking about I did a vid on it with my custom setting's that I use on a regular basis.

My experience too. GPU off is faster than GPU activated in VP 11. My test is in this thread:

GPU accel is separate from the CPU and if your CPU is super-powerful (in relation to your GPU) then it would be slower.

IE if you bought a brand new GPU & CPU right now, the GPU might be a little faster or they might be the same. If you use a two year old CPU & a modern GPU, the GPU will be a lot faster (and most likely cheaper then buying new RAM, MB, CPU, etc, and easier to install). That's where the benefit really shines, a much easier way to upgrade & get acceleration.

My CPU and GPU are a couple of years old but I'd like to see evidence of improvements when using a new GPU and an older CPU. Neither Sony nor Adobe specify the CPU/GPU combination. They just claim that GPU will speed up playback and rendering times. In my experience with VP11 that's not the case.

During rendering, is V11 using 100% of the CPU? (According to Task Manager in Windows...)

With my overclocked 6-core 980X 10e uses 100% of the CPU - all 12 virtual cores are maxed-out. My video is stored on fast RAID hard drives rendering to another set of fast RAID hard drives... Therefore on my system most HD work renders at a nearly a 1:1 ratio. For instance, a 2 hour video takes about 2 hours to render.

HOWEVER, Vegas 11.595 only uses about 60% of the CPU regardless of how I set the number of rendering threads used or Dynamic RAM Preview. Vegas 9e also uses only about 60% of the CPU. With 9e I can render two projects at once without any problems. With 11.595 I cannot render two projects at once without having serious render to black issues. 10e sometimes renders 3rd party codecs to black but it is fast-enough at rendering that I do not mind so much having to redo the render. Usually if I split the offending clip into smaller segments, save & reload Vegas it will render fine the 2nd time. Checking for black frames is now a part of my workflow for 10e and 11.595...

I updated my post with a vid, but the times are not improved over using the cpu in vegas 11, however some times are improved over vegas 10 depending on the codec.
