After Effects Texture Memory doubt

[Walter Soyka]

Ae does not generally render on the GPU. The exceptions are a few third-party effects (like Video Copilot Element 3D, Mettle Freeform, and Red Giant Universe), the native Cartoon effect, and the ray-tracing renderer, which is no longer under active development [link]).

See more on Ae’s use of the GPU here:

[Adriano Castaldini] “1. what does Fast Draft do?”

Fast Draft is an OpenGL-accelerated preview mode. It’s pretty useful for layout in comps that use the ray-tracing renderer, because it renders fast. However, its use ends there, because its quality is draft-only. You cannot render Fast Draft.

[Adriano Castaldini] “2. is a good idea to push up Texture Memory from 4915MB (default) to 9216MB (the max value that I can get)?”

Probably not.

Thanks a lot!

Just another doubt:

The difference between enabling CUDA in Ae CC2014 vs CC2015 is the location of raytracer_supported_cards.txt file (where you add the name of your card in order to make it recognizable by Ae): the difference is that it was stored into Ae CC2014 Content folder, while in CC2015 it’s in Content/Resounces folder.

Now, I need to find (and update) the cuda_supported_cards.txt file that in Ae CC2014 was in Content folder and now in CC2015 I’m not finding it nowhere.

Really thanks.

You don’t need to modify the .txt file in recent versions of AE. There is a checkbox that allows you to enable GPU acceleration on “unsupported cards”. The thing is, the Optix library on your card CANNOT work to accelerate the ray-traced renderer because NVIDIA changed the library that the effect relies on. No matter what you do with .txt files or anything it simply cannot work.
The next update to AE [link] will update the Optix library of the ray-traced renderer so that it can work with the new cards, but until then, YOU CAN’T DO ANYTHING to make it work.

Again, as Walter said, the ray-traced renderer is a dead end path. I would recommend against wasting any time working with it. Instead, learn how to use the more powerful new option [link]!
