JDN's performance issue [split]

Forum rules
Contrary to popular belief, we are not all-knowing-all-seeing magical beings!

If you want help you're going to have to provide lots of info. Like what is your hardware, what is your operating system, what version of GZDoom/LZDoom/whatever you're using, what mods you're loading, how you're loading it, what you've already tried for fixing the problem, and anything else that is even remotely relevant to the problem.

We can't magically figure out what it is if you're going to be vague, and if we feel like you're just wasting our time with guessing games we will act like that's what you're really doing and won't help you.

I spend hours searching for settings that can help but nothing.
But I have fullspeed when using software rendering. :?

So now I have two folders, one for my 3.2.5 and other one for new versions.

by real maps, can we say the Hunter's Moon maps ?
that is real heavy work for my CPU... but it works well when no monster run somewhere.
just a little lag.
Hunter's Moon map + Hunter's Moon weapons and monsters... and there, i'm reaching the limits of my CPU.

Hard to believe. If this was a map that actually performed some real work that might be the case.
Just out of curiosity: How does this system handle some real maps? Although your card is relatively weak by today's standards it's not that bad for an old game like Doom. Something must have changed in GZDoom to affect this particular system this badly and I have no idea what it is or whether it may affect others too.

maybe my computer was just at the limit it can bear with 3.2.5...
and maybe the updates added in new versions were the "liitle thing" that bring me some lags.

The strange thing here is, that nothing in there suggests such a performance hit, the map basically contains nothing and even the increased vertex count due to the new approach is nowhere near problematic.

Yes yes sorry, it was a joke... :oops:
I know GZDoom is a modern (and very well done program).
I didn't want to be impolite with people who create this masterpiece.

This remark is completely disingenuous and omits some very important things.

Your computer is too old to use a 2018 program that happens to play a 1993 game.

You can still use doom.exe to play a 1993 game on a 1993 computer.

open the console, type 'bind b bench' (or any other key if you do not want to use 'b'), then make a savegame at a place where this slowdown happens, load it into both engines and press 'b'. A file named benchmarks.txt will be saved. Post that here.

edit: "Can you do some 'bench' dumps from an affected scene? "
how can I ?

There shouldn't be such a massive change between 3.2 and 3.3, though.
Can you do some 'bench' dumps from an affected scene? Maybe that gives some clues.

I remember on my old PC, OpenGL performance would take a significant hit whenever a skybox was being rendered. (I think around ~40% FPS reduction?) It sounds like something similar is happening here. I haven't used that PC at all for a long time though, so I can't speak to its performance with any recent GZDoom versions.

I'm using speed settings...
(in fact I use same .ini for both versions)
and I'm trying new version on basic Doom2 so it shouldn't be too hard for my computer...
(My CPU with 3.2.5 work perfectly with wad like Hunter's Moon if you see what I can do)
it's just something in newer versions that say no to my computer... :blergh:

It's normal for the renderer to run slower in detailed areas on low-end hardware. I've done some testing on my crappy intel GL 2 card and i see no noticeable differences between 3.2.5 and 3.3.2 so i guess you're unlucky with your hardware or may be is a Vista thing. However i mostly play with ZDoom32 on this old machine since the old renderer was faster here.
Edit: do you have the rendering quality setting set to quality? If so set it to speed, it was fixed in 3.3.0.

So yes my 3.2.5 (whitch is in my MAIN folder) work very well. and at full speed.
For other versions, I used the SAME .ini but I put them in an other folder.....
I even tryied once to put my new version in the MAIN folder...

no matter what, once I "upgrade" my 3.2.5 to anything else... BAM, LAAAAG. (only in exterior areas)

that's strange that the only moment I feel this LAG in whe I watch an outside area or when I walk in it...
as soon as I watch again inside a room or when I come back IN the room, that work PERFECTLY...
