I'm on an 8 core Mac Pro with a GTX 670, Adobe CC. Raytrace is so slow I hate to use it. interactions are nothing short of pathetic. Even bad at 1/4 resolution. I thought maybe it was b/c I have 2 27" cinema displays and it is just too many pixels --- but maybe I'm wrong. Maybe it just sucks?
I have latest Cuda drivers and all that. If you guys know of something I can do to improve the performance - please share!
The GTX 670 is not lsted as a card that After Effects will use for GPU acceleration of the ray-traced 3D renderer:
Your poor performance is because rendering is being done on the CPU.
When I go to pref > previews
GPU Info (I turned down the texture memory)
i just did some tests turning gpu on and off - and cpu is even slower. we're talking with gpu - and 20 characters of 3d raytrace text - 8 - 12 seconds or more when moving playhead any amount. cpu might take 40 - 75 second for the same move.
i got cloud for the c4d integration - but so far it is def. not been worth it. much faster to work in c4d - render - then import into cs6.
Because the GTX670 is not specifically supported by After Effects, you will get terrible results from the ray trace renderer - virtually unusable render speeds. You can submit a request to Adobe to provide support for the card, but they will only action that request if they get enough requests for that specific card from users.
You mention the ray trace render feature in your first post, but Cinema 4D integration in your later post. What kind of render performance are you getting using the Maxon Cineware plugin?
C4d is just as bad as Raytracer -
I have only ever put in a cube and a piece of text. Too slow to work with - so I always just go back and work in C4d - or Lightwave and render and import....
Should I wait on this card to be supported? or start shopping for a new card? I can't work like this....
It's a 3,1
IDK what's up w the shader model #
I looked at a benchmark for this same card / computer running CUDA and raytracer etc.
It was a robot in after effects - a benchmark scene. it said I should be abel to render it in 16 seconds. it took 18 minutes.
im really disappointed. not sure what to do. sell the card? IDK.
I was reading on another site to do a cuda update through the cuda control
panel. I know for a fact that card works great in ae cc. We have to get
that shader model figured out. I'll help more tomorrow

Everything I read says the card should work with the raytracer_supported_cards.txt updated. And it shows in the AE raytracer GPU panel
Seriously.... I need some help here. If there's anything you sould do - I can't tell you how much I'd appreciate it.
I feel you pain. After ther first clip I render out through media encoder took 4hrs for a 15 sec clip. I decided to do it through premiere and was rewarded with this surprise. It ended up taking around the same time, but my heart sunk when i saw this. That is the last time i use 3d in AE until this is fixed.
