When i render a project. 3-4 tracks, simple stuff. it does not matter the format i am trying to render to, the projects freezes anywhere between 9-13% completed. I have tried all different sorts of rendering templates, and even customizing them. nothing seems to bulldoze through.
The sad thruth is that VP13 is not yet error free concerning GPU rendering. Occasionally you have to turin it off. I have still issues that are related to video FX that also use same GPU resources. There is something in how these share the GPU that seems to cause trouble. The situation is as unfortunate as it is sad. How many releases (paid or bug fixes) do we still need before this works reliably? Will it ever?
GPU acceleration works fine with older cards like the Nvidia 560Ti and higher or HD 5000 and 6000 series but not dual GPU cards. Quadro cards work fine too and it might just be a driver issue with your system . The Quadro 2000 as well as the FX series are not strong enough and even if it would work in your system, I doubt it would be any faster then CPU only. If you are in the US and want to take advantage of GPU acceleration get yourself a second hand card for around $100.00. However, keep in mind that for rendering, only MC AVC, Sony AVC and most MPEC encoders are GPU accelerated.
Well, I'm pretty sure VP13 GPU rendering is a bit broken. As discussed on other threads VP11 seems both faster and significantly less crash prone. I've got a project that VP11 renders without problem and VP13 cannot render at all. Stabilization in VP11 is much faster than VP13 as well, so something is wrong with their GPU code.
When I first got VP11, it too crashed and hung on rendering, but they did an update eventually that fixed it. I've never had VP11 crash on GPU rendering since. Perhaps Sony will fix VP13 someday.
I haven't had a crash on all three versions, 11,12 & 13 with GPU on. I had GTX460, 560, 570 and now 2x GTX580 and 1x HD6970 in my system, no issue what so ever. Yes, there is a difference in render time of around 5% on my machine with driver 296.10, I haven't had time to test this with driver 334.89 and my "tweak" for it.
