Just tested on Windows 10 and no problem there.
More tests. It seems that my PC is too good :p I changed the render threads setting from 0 to 6 and the parallel threads to 4 and now it seems to be mostly ok. The RAM usage is still high and the CPU usage is high when rendering but most importantly the playback is now smooth.
Can you please give details about your CPU? The output of lscpu
would be nice.
I'm reopening this for now.
Of course, it's a 6 core Intel i7-6850K @ 3.6GHz.

Do you have enough RAM on that system? Natron requires a lot of RAM, especially when multithreaded.
I assume so - 64GB
What does the value 0 for noRenderThreads correspond to on Linux and Windows? is it 12 on both, or 6 on one and 12 on the other? What fixed the issue: setting noRenderThreads to 6 or setting nParallelRenders to 4, or the combination of both?
the value that corresponds to 0 for noRenderThreads can be seen in the help tooltip
I changed both so I'm not sure which fixed it, I'll have to do some more tests
Same problem here. All my system RAM is fulled, even setting that I just want to use 50% of my system RAM in cache settings.
I have 32GB of RAM and an AMD 5800x processor.
Problem
I have a read node pulling in a video connected to the viewer. That's all. I hit play, the preview lags like crazy, CPU hits 90% and RAM usage shoots up to 2-3GB. Playback is really choppy too.
