When is PrBoom+ overflow emulation necessary?

[Legatron17]

So in PrBoom+ (2.6.2), there are 6 types of overflows you can "try to emulate" in the options, which leads me to a few questions:

 

1.) Which emulations are demo relevant and which ones are not?

2.) Are these settings overwritten when launching the game with a certain complevel, making them unnecessary to mess around with?

3.) If they are not overwritten, which emulations do you need to turn on for complevels 2, 3, 4, 9 and 11?

 

I personally have all of them turned on in complevels 2, 3 and 4, but I'm not sure whether or not that's the correct thing to do, let alone what needs to be turned on in complevels 9 and 11. Answers would be greatly appreciated!

1.) I believe all of them are demo relevant.

2.) They don't get overwritten.

3.) Typically it's best to turn on all of them. They get ignored in complevels 9 and 11, since the source ports these complevels emulate fix those overflows already.

I just tried out a map specifically designed to cause an intercept overflow (which is the only one I actually understand and creates ghost monsters), and yes, it does seem to completely fix the bug on complevels 9 and 11, but not on 2, 3 and 4. I don't know how to test out the other overflows, but I'm just going to assume that they behave in the same way when it comes to complevels, so I guess it's best to have them turned on at all times. Thank you very much!
