Now the plugin is not needed and the feature of enabling DirectWrite is in npp itself.
Is it starting with Notepad++ 7.8.8? With 5.11 you should see some improvement in performance, due to cmap access reimplementation. It's possible it's not enough, and unfortunately last time I tested (with 7.8.6), scintilla dwrite backend is poorly optimized itself - it using text layout API, which is meant more for static or rarely updated text, rather than text editors. Basically what happens is that layout object has to be recreated on every text change, and they seem to recreate it even more often.
