well, based on Topaz since v3.012 there were two iterations that had performance boost:
v3.1 including on RTX 3080 (from 334 sec for 10 sec video upscaling to 4K down to 174 sec).
and on v3.2, another performance boost.
how about you download the latest version (Demo mode) encode a 1min clip from your usually upscaling library and compare the results for yourself compared to your v3.011? that would be the best real life results for you.
Because they do much better job then other programs and that comes with a price, performance.
more time you spend processing, better results you get. it’s very simple.
