R16, PC, GTX 970

I edit BRAW 4K in a HD timeline, which went smoothly in the beginning.
The longer I edit, the more Fusion compositions, the more problems arise: crashes and "GPU out of memory", "To many nodes, reduce the number of nodes" errors.

I already turned off caching/rendering, still bad performance. And I still need to add some clips/nodes in Fusion and still have to do all of the color correction.

Does it make sense to merge the fusion compositions into adjustment clips, so they don´t have to be calculated anymore?

How else do I get a better performance?

I think ultimately you'll find that to complete this job, you need a better GPU.

What you could try is doing all Fusion stuff in the standalone version and render them in good quality, then use VFX Connect.
But as Jim says, without a better GPU there will be no smooth sailing.

I cant get a decent GPU right now, they are sold out. My GTX970 is not that bad, to get something double as powerful I would have to get at least a RTX 3060 TI. Impossible to get right now, all sold out.
Therefore I have to finish this project without a new GPU.

Is there a way to render the Fusion stuff without a standalone Fusion (or do I get standalone Fusion for free?)

In Avids MC you simply render once in position and never have to render again.
Why is this not possible in Resolve?

What about adjustment clips?

I think you could do the same thing in Resolve by 'delivering' the clip with the Fusion bits then import the delivered (intermediate) video into the project on a new timeline that does not have any Fusion. The downside is you would need to deliver the original timeline if you made any tweaks to Fusion. The upside is that the second timeline would not need to process as much since it would have the results of the Fusion and not the Fusion itself.

If you have Resolve Studio you can use Fusion 17 standalone too.
BTW, if I understand you correctly, Resolve 17 has what you are asking for from Avid, called "Render in Place".
