• Add SPF_NOMIPMAP to force actor sprites or particles to have no mipmaps. This makes tiny sprites/particles look more crisp and legible in the distance.

• bail out if `shape` is null in `F2DDrawer::AddShape`

• fix kill count management in CopyFriendliness when used on corpses.
• fix MBF21 ClearCountItem
• fixed a few memory leaks
• set a default value of 1.0 for `MissileChanceMult` property
• added CVAR to select the preferred MOD player and SNDINFO option to set it per song.
• added a menu option for switching module players.
• Add bounds checking to GetMidTexturePosition, add assert to P_GetMidTexturePosition
• Made GetMidTexturePosition() const.
• Use a `light_` prefix for custom ZDRay stuff, and actually parse light_softshadowradius for map things
• Updated ZDoom UDMF spec changelog.
• Orthographic projection Widescreen aspect ratio horizontal clipping fixed. This one-line change only affects ortho viewpoints. Easy to verify in windowed mode.
• avoid floats in integer math.
• use newer zmusic
• Added MF9_FORCESECTORDAMAGE.
• don't spam the console log if there's math errors - mostly affects Linux/MacOS because there is no distinction from console apps or GUI apps so they put all the data in the console which can cause lag

[Rowsol]

I guess I'll finally update from the broken 4.11.
Thanks.

[Deybar_TECH]

I'm curious about that Orthographic-projection feature.

[Cherno]

I'm curious about that Orthographic-projection feature.

Thankfully dileepvr provides a short description of the process to set it up. There's also a detailed wiki article.

Use any regular camera actor (or the included SpectatorCamera). Use its viewpos field with flags VPSF_ORTHOGRAPHIC. Set a non-zero length for ViewPos.Offset vector (this controls scale, the equivalent of fov). And that's it.
Have it pitch down or up a little to get sensible viewpoints.
For a useful camera, set flags VPSF_ABSOLUTEOFFSET | VPSF_ORTHOGRAPHIC. Then you can set the viewpos and angle and pitch up to always look at the camera postion, and then move the camera to the center of the scene.
[...]
For completeness (in case someone new sees this), setting player.camera to your custom camera actor will make its view the main view. Set player.camera to player.mo to restore defaults.

For lack of a better spot to post this, I'll leave this here. It's a showcase of the performance of this program throughout the years. This is not meant as anything other than to document the changes.

[Graf Zahl]

That entire video is completely useless unless you post the specs of the system(s) you tested on.
One important thing to remember is that as time went by, several defaults were changed to use more costly but higher quality settings, which of course does not play well with older hardware.

[Rowsol]

ok.

10400, 1650 super.

Not exactly old. Built it 4 years ago.

Simply loading up 4.10 raised the fps by almost 10% and they use the same .ini

I know Graf sometimes is "too direct" but I can agree with him.

Step 0: knowing the hardware gives context. For example: does the GPU support Vulkan?

Other things to keep in mind for my experience: configure the drivers. I've found nvidia drivers are getting complex and complex every release, which means some tune-up might help.
For my Ryzen 5900x and RTX 4070 helped a lot enabling G-Sync and put the settings into performance mode and enabling DXGI swapchain for GZdoom and in Sunlust God machine I have at least 80 FPS.

O/S and drivers change too, so IMHO, it's a test without tune-up is kinda useless.

[Rowsol]

Here's the old versions to try for yourself if you don't believe your eyes. https://www.mediafire.com/file/dcrwc8yd ... ns.7z/file
I won't comment anymore on the matter.

[merlin86]

As I answered in Youtube IMHO there are some problems with the map.
1) It has too many enemies: 41k is a lot. Maybe DSDA and other ports like that might help. With my 4070 and 5900x I get around 60 FPS with a pre 4.13 version from Github. For example VKDoom I get like 41 FPS, i need to investigate that, might be an error on my end.
2) The map looks big: AFAIK GZDoom has problems with really big maps: Making smaller maps in a hub might help, have a look at Selaco it has smaller maps and its performance is really good.
3) GZDoom changed too. Now there is ZSCript and looks pretty complex to manage, maybe it requires a more powerful CPU / GPU , but still there is nothing wrong with optimizing stuff even if you have unlimited resources.
4) If the map doesn't use some fancy GZDoom feature you could try Helion which removed BSP altogether, I saw with that port huge spikes in FPS even in really complex wads.

EDIT: I can confirm with Helion I have a solid 144 FPS but Helion doesn't use BSP at all.

[Graf Zahl]

Most of the time gets lost while ticking all those 40000 monsters - sorry, but that is far too high for stable frame rates, even on a high end CPU. The difference between 4.x and 2.x seems to be some compensation that evens out frame times - on 4.x it's rather consistent 12-15 ms on my system, but on 2.x it wildly fluctuates between 1 ms and over 10 ms (it's too fast so I cannot make out the actual number. ) Due to these high fluctuations 2.x doesn't really feel smooth, in fact I find the more consistent frame rate in 4.x far less annoying.

I never added such compensation code, does anybody else know about it?

[merlin86]

I can confirm with -nomonsters I have a solid 144 FPS. The problem are the high monsters count. Splitting the map into smaller pieces with fewer monsters per piece should help.

[dpJudas]

I never added such compensation code, does anybody else know about it?

I added code that slows down non-ticking frames to the same time as the last ticked frame - exactly to avoid the micro-stutters from the 2.x series. A high FPS on its own is useless if it isn't smooth IMHO.

I can agree with that, makes sense.

Is there a point to this other than ragebait? Because using a map with 40k enemies to benchmark anything feels like a joke. Some people reported even DSDA Doom had spots where this map chugged.
