Image Preview stuttering

Hi,

when generating a large image of i.e. 8000x6000 px with the new chart nodes and previewing it, the rendering is stuttering a lot.

Hey @mwiegand,

Thanks for sharing your findings,

How much memory do you have allocated to KNIME? It may work better with higher allocations of RAM for previews of a large image.

Hi @thor_landstrom,

let’s just say plenty :wink: Of the total 64 GB GGD5 low cast latency memory more than 50 are allocated which were not fully utilized. The Graphics card also is “decent” with a RTX 3080 Suprim X with 12 GB. If rendering was done via CPU, the AMD Ryzen 9 7950X 16-Core / 32 Threads didn’t sweat either.

Cheers
Mike

That should be way more than enough memory (that is a neat setup you have on a side note).

The CPU should be able to easily handle something like that also, let me go ahead and create a ticket internally to look into performance optimizations for the preview.

I suspect there may be some bottleneck somewhere, and it most likely isn’t hardware related.
