No they didn’t ask nicely. It’s one thing to say “i’m having trouble with this” or “did i do something wrong” or “do you have any performance tips” but it’s another to just come in and say “these are the performance numbers i got, so therefore this thing is useless” which is exactly what they did.
Not only does it make the assumption their performance is the only one that matters, but also dismisses the fact that plenty of developers have been using this plugin for a long time. On top of that did you seriously just say I don’t know anything about the plugin? …because I’m literally the OP. The fact that you think I don’t know this uses the CEF without GPU acceleration is beyond laughable. Why don’t you go back to your little vector graphics library and focus on the 10 people that downloaded that.
