Yeah Filmconvert uses the gpu, it has a cpu/gpu dropdown menu option right in the effect. It's actually unusably slow in cpu mode though even on a quad core Haswell, it all but demands a gpu really.

No improvmend on my pc with the GTX 970 after update. Gr Micky

Thanks a lot for this new driver.
On my system, the playback speed improves drastically
As a test using the rendertest JR, I reach 22fps now, instead of 17fps with the old driver (334.89)
Playback speed with 3rd party plugin are also a lot better.
However, no improvement wwith render speed using Opencl, but with my old GPU, that's not an issue.

I just tested the hotfix and there is a slight rendering improvement for me (~5%), but this improvement showed using both cuda and opencl presets. What makes this even more interesting is I running 2x gtx 970s in sli so there is no cuda support. I had 2 instances of new blue titler and hitfilm denoise in the test project so I'm guessing the improvement is with whichever gpu acceleration these plugins use. The playback frame dips were slightly better when the titler events occurred (from 7 fps to 12).

In any case the timeline and render performance is horrible in Vegas with the 970 (previous card was a 580). Hopefully Nvidia officially dropping driver support for NVCUVENC will finally prompt Sony to include support NVENC.

Nvidia may have added OpenCL 1.2, but it's still just as crippled.

I purchased a GTX 980 for use in Vegas. It seemed to work somewhat at the beginning but after a driver update the benefits disappeared completely.

Is there an older Nvidia Driver I can roll back to that will make it work at all?

You could try this Jordan, I haven't tested it because this was still included in the 600 and 700 series drivers but these generation Nvidia cards didn't accelerate Vegas either.

Dave,

I feel your pain for I just bought the 970 and all my renders are 40% slower than the 500 series.
It is interesting if I had a project that was a 15 minute render using the GTX 580 my timer would go up to 15 minutes. When I use the 970 card it goes all the way to 42 minutes than starts decreasing to a final render of 25 minutes.

If there a fix? I went to the link above and it was a removed.

I run and old 780ti for display etc and have the 980 selected for render on vegas

I had to do a reset of vegas first to get it to pick both cards up, might be worth doing that first.

Then try going into the internal advanced settings and set the OpenCL Filter memory size filter to a larger value, I set mine to 3000 the 980 has 4 gig and the 780 has 3gig and the 980 started working better. I'm running the latest drivers and it looks like vegas making much more use of all my resources, regularly get both cpu's maxed out now and usage on the cards is up.

It's not like wow that's amazing but it works for me, can play and edit 4k fine without proxy, soon bogs down depending on what effect you use but obviously don't have them turned on for the editing part.

One think i have noticed editing 4k is i get much smoother playback droping 4k in the timeline and getting it resizing to 1080p on the fly, I would have thought this would make things worse but it's smoother, I've been wondering for a while now if they restrictions are more about how big each frame is decompressed and moving that about rather than the cpu/gpu and there may be a way to better optimise that but it's working well enough for me that I haven't bothered looking further for now.

Hi Mark,

How do you go to INTERNAL ADVANCE settings and OpenCL Filter memory size filter?

Cheers,
Randini

I found it from user Aaron Star. Now he says to do all this...should I?

Have you gone into Shift+Preferences > Internal > type mem in the show only box, then up the OpenCL memory Size filter to 4096. Restart Vegas and retry MC AVC with openCL and Sony AVC with OpenCL and Auto, and see if the numbers improve.


Switch to FP32 mode and see if GPU use significantly improves as a test. Try rendering some XAVC-I and play it back, and note GPU usage. Render some HDCAM-SR-LITE and playback in 32FP mode, and note GPU usage.


Some other things to experiment with might be:

Threads in show only prefs. Experiment with changing the MIN/MAX threads to match your system (16) Experiment with Reader threads at 16.


OpenCL in the show only Prefs. Experiment with OpenCL Per - Thread Command Queue = True

I set my OpenCL Filter memory size filter to a larger value, of 3000 using my GTX 970 and still same results of 40% longer render than my old GTX 580. This has not only cost me $400 but much headache. A faster video card should not slow anything down!

@Randini
why did you change from a fully supported GTX580 to the rather unsupported GTX970? This forum is full threads related to GPUs and it has been mentioned over and over again which cards are supported.

Old Smoke, after 5 years editing over 400 (30 minute videos) my video card SIZZLED OUT making white lines across my screens. I sadly did not research the compatibility issue and bought the higher end one just thinking it would be better.

Should I go buy one of these 580's?

Thank you,
Randy

it depends on what you are after. If you very fast render via CUDA for MC AVC codec then yes. If you want better timeline performance and do a lot of MPEG2 renders, I would rather buy a R9 290.

I just bought the R9 290 and installed it with the latest driver and I'm still rendering slower than my old GTX 580! Is there some sort of tweak I need to make in the settings. This is very frustrating after purchasing and returning 3 video cards.

Also all the new cards won't let me render MainConcept mp4. I get error that reads can't find.

Randini

The R9 290 is not supported when you want to render to MC AVC or Sony AVC. However, the R9 series is currently the fastest card when it comes to timeline preview. It is also very fast when rendering to an MPEG codec such as for DVD, XDCAM and so on. If you want to render using MC AVC to MP4, the GTX580 is the fastest card period.

Try the Vegas2Handbrake method. This will give good render times and much better results. Do a search in this forum for it. Its bit tricky to setup but well worth the effort.
