Unfortunately I am having very unstable results using GPU rendering in Natron 2.3.14 and I was encouraged to make this post by some people from the Natron discord as I don’t seem to be the only one.
I will focus this example on the cryptomatte keyer node, as that is best example I have, and most important to me. But it happens with other community plugin nodes too.
When using the Cryptomatte Keyer node the renderer stalls and prompts me to kill it and restart Natron if I wanted to continue working.
This image shows what error messages I get when using the cryptomatte keyer node in the community plugins ( The one by CGVirus on youtube) with OpenGL rendering turned on. (Note: It doesn’t matter what kind of node the renderer was crashing on, it was just a matter of the Crypto keyer node was part of anywhere in the composition)
I asked for help on the Natron discord and that gave me the idea to try and disable my GPU rendering. And doing so have gotten rid of any error logs or hanging renders that need to be killed and Natron restarted. So it seemed that the issue was the GPU rendering. and not the nodes.
I am on windows 10, Using a RTX 2060, OpenGL version 4.6 with the latest Nvidia studio driver. 441.28( I’ve tried going back to older version too. 434 from july.)
I hope to hear back with any feedback on what can be done about this. And if there are any fixes I could apply to stabilize my use of GPU rendering, as using CPU rendering only seems to run very slow in comparison.
