Maybe there should be a Path Tracer Check which goes through settings and offers the best optimized settings? Maybe even warning of settings like excessive MPD and stuff. Just a thought. The Animation Checker is very handy for settings things we'd often forget.
Good idea. Like for the animation module. But I don't think you can set a cut-off MPD value. If a render can benefit from a value beyond the "max recommended" it should not be barred from using it.
Well, that's why I did say a warning. But in general the PT works with MPD differently, where you actually dont need as high MPD as standard renderer.
There are other aspects we use in standard too which would slow a PT render unnecessarily too.
