I found myself often setting the deck to 50 fps to save some performance but still get a very fluid picture.
Do you think running the deck at the highest frequency and halving that will be substantially better then anything from 46-50 or maybe even 46-60 at native frequency?
Yes, because it’s still able to process input through the duplicate frames provided by 45fps at 90hz. At 45/45 there is a gap between refreshes where input cannot be processed.
