Maybe. It depends on a lot.
Right now I think I have at most 3 bursts on screen at once, and my frames haven't dropped below 40 in play testing.
I think some of your bosses have more shots on screen than I do
Hmm, from discussions with Chris, I've found that hitting 40 might actually be an issue.
Well, what's your usual FPS in-game? Like, when you're just playing in average rooms with an average mech? I'm curious to know how far it goes down if you really spam that thing VS how it normally is.
With alot of the bosses, including something like Centrifuge with it's extreme bullet count, they're actually using bullets that have no true collision on them. The game doesnt have to process any possible terrain interactions (aside from bullets hitting the boundary of the room, if I recall correctly), and the bullets tend to just keep going when they otherwise wouldnt. It was put in because alot of bosses were actually causing issues on some systems. Obviously this isnt doable for all attack types (like Mirror) so I had to remove it for some, but most are still using it in some form. Basically Chris went in and did a variety of things with stuff like that to keep them functional yet reduce the draining effects they were having. Like how Crystal Mother's purple laser things were changed; they function the same but now use far less bullets than before.
Huge amounts of bouncing shots can be an issue, which may need to be looked at. Chris actually may have some ideas on how you can keep the drain to a minimum while still retaining all the function, if it turns out that it's a bit much.
