Did you install Natron using the official installer?

[X] Yes, I used the official installer
[ ] No, I installed from a binary archive
[ ] No, I compiled Natron from sources
[ ] No, I installed Natron via another method

What were you trying to do?

Play project

What did you expect to happen? What happened instead?

Natron is not using GPU for rendering (not appear even in "nvtop" command line program).

Step-by-step reproduction instructions

Start Natron
Open gnu.ntp project
Click "Play forward" button

Natron uses the CPU, some nodes can use OpenGL, that's it.

Are there plans to use GPU in next versions?

rodlie commented 1 year ago

Not really. The primary focus is maintenance and bug fixes.

I am sorry to read that. I thought Natron was also looking to optimise its performance. Personally, on my Intel i5, Natron is so slow that an acceptable workflow becomes impossible, not even for testing (I have loaded your examples from the web). After my experience, in my opinion, I see Natron as a good idea (working with nodes) as Resolve does, but in practice, Olive (which also includes nodes at a more basic level) works with a more than reasonable level of optimisation.

Thank you for your great job
