Both in conjunction appear to help. Wigglypaint is the smoothest with both patches. I can draw with the pen and the marker doesn’t skip when it paints under it. Normally, it skips a lot for me. Also, the other way I can tell is if I load my Huffman deck and paste a large amount of text it it. Usually the menu and the listener are nearly impossible to use. With these, it’s somewhat acceptable, though still slow.
I didn’t know what was the best way other than eyeballing it. I can tell it’s smoother, but for “raw computation” it doesn’t make a difference. I don’t know if that’s due to how things get timesliced between rendering and compute.
If you can tell me a proper way to benchmark this, I can do the hard work to test it if it’s worthwhile - I know empirical eyeballing is a bit hard to judge.
