This is not a bug.

The reason for the FPS drop is because GZDoom - like any other game - has to draw every single splatter on every single frame. It cannot save the splatters between frames. It does not "paint" the wall with the splatters. Game rendering simply does not work like that. Every time the game advances to another frame, it has to redraw the entire scene from scratch - including putting each individual splatter back on the wall one by one. That is why it slows down.

So yes, if there's a thousand splatters on the wall and your GPU is a piece of shit from 2005 - your FPS will drop.

You can fix it by lowering the maximum number of decals drawn per frame - you can open the console and type something like cl_maxdecals 64 (default is 1024). Note that this will make more recent decals erase a lot quicker as they get older.

Well - I explained to you what you need to do to raise your FPS back up. Modern GPU or not you're still overloading the scene and that's not GZDoom's fault.

Zandronum does have the problem. In fact it is even more CPU-bound than GZDoom since the renderer is considerably older. You probably are just running on different settings there.

Then there's something wrong with either your system or your settings. The problem is not GZDoom.

This is not the place for your bad faith arguments about how GZDoom is so horrible just because you saw some moron's video on Youtube (not the one you linked, obviously) who, himself, pretended he knew everything and also made a bunch of assumptions in bad faith, just so that you can parrot what he says without ever thinking about it. The problem is on your end. Fix your settings.

And this is how you earn a one-way ticket to ban town.

If you're going to argue something, especially trying to claim it as "true" - you better both A) be right, and B) know what you're talking about. We really don't have a high tolerance for bad-faith BS here. Always research the topic first, and always have some solid evidence to back up your claims.
