About the “burden”, let me add a couple of considerations…
Other RAW developers are MUCH, MUCH faster in generating a preview than PL. And they manage to be faster while at the same time NOT having this blurriness at any zoom level.
So, it’s not only a matter of allowing sharpening/microcontrast/aberrations correction at zoom levels below 75% (optionally). It’s a whole matter of complete rewriting of the visualization engine, because there is plenty of margin for optimization both in terms of performance and quality.
And that’s why I hinted at why GPU acceleration (so brilliantly used for DeepPrime) could be used also for speeding up the viewer.
No more blurriness at any zoom level AND better performance? A dream, but doable!
@sgospodarenko remember how many times we already had this discussion?
