There is no Vanilla based engines with those features, so I want to see it in QuakeSpasm. 

tyrquake 

Its exactly the same as WinQuake even with no proper widescreen resolutions support and this port has its own bugs, so it has no sense. 

tyrquake, compared to WinQuake, can render more complex maps (BSP2 support) and has model interpolation. It also has alpha support for models and liquids, including the software renderer.

I'd say it's otherwise close to WinQuake, but it certainly has improvements. It certainly is not on the feature-level of quakespasm.


Talking of which: I noticed vkquake included QSS' support for decoupled render/physics framerates: https://github.com/Novum/vkQuake/commit/ffc9adf2ec52d3b786f6e80c61f3eabea697eacf

Looks surprisingly non-intrusive and should not alter behaviour for framerate caps up to 72. Is this something that can be considered for upstream inclusion? 

iirc the 'decoupled render/physics' is from quakespasm-spiked. And it does have limitations.
if you are on a huge map and your frames drop below 72 it starts to produce a slow-motion effect the further away from 72 you go. And on the opposite end, the higher you go over 500fps, it gets faster.
but, for the 72-500 range it works fine. And it's not the logic of the code, it also happens on othe independent physics code i have tested. 

Yeah, that's code from quakespasm-spiked.

As for problems above 500 fps - well, capping it at (pulling a number out of thing air) 300 fps would still enable a match for all modern display devices, so that's the easy case.

Slowmo below 72 fps, of course, is a problem. I wonder if the engine could detect that and switch dynamically as per situation. 

Basically, grab the current fps value, if its < 72 then turn off the independent physics code, and let the engine run like normal. 

same for > 500 too. 

You could also run multiple physics frames of the renderer is running slow. 

is anybody able to use the -ip flag on linux? it works fine on windows, but it seems to be useless on linux. other flags like -game or -dedicated work fine, so i don't think it's an issue with flags in general. it defaults to 127.0.0.1 no matter what ip is specified, which does not seem to be a problem as long as you have a linux client and server, but windows clients can't connect to a linux server in this configuration. i've tried it with regular qs and qss 0.93.2, both have the same problem. using qss the problem can be avoided by launching an automatically configured server from the menu, but running it as dedicated still gets you stuck at 127.0.0.1. 

I bought first Quake and its mission packs in Steam. As many people recommend, I installed QuakeSpasm, and even installed soundtrack for all three games, and got Steam Overlay work with QuakeSpasm.
QuakeSpasm menu works OK - options and everything. But I pushed to start a new singleplayer game. Spasm crashes. Then I looked up, that I downloaded x64 version cause i'm using Win10x64. I reinstalled to x32(86) - the same problem.
Also, I tried to enter the game through console - "map e1m1" - the same problem - crash.

Sorry for my bad english, I tried to be correct as possible as it can be for me. 

Are you on a laptop? What video card are you using? Can you play with a software rendered engine like Super8? http://super8.qbism.com/

How about a WinQuake?

You can also try Mark V's version of WinQuake: http://quakeone.com/markv/builds/1099_mark_v_windows_revision_4.zip 

I've been able to reproduce this and fix it (or work around it) on a test machine by running with -noglsl.

The symptoms were broadly the same as you - the engine starts up OK, I can navigate the console and the menus, but as soon as I start a map (in any way) it exits silently and nothing is logged.

That seems to suggest that something's going wrong in the VBO loading code, and I hope to get a debug build going on this device soon-ish. 

Bit of an overdue update.

It doesn't crash in a debug build, only with the released binary. I guess you need to run with -noglsl then. 

I did a quick hack of my own build of Quakespasm so that it supports "-ad" and "-copper" arguments in a similar way to the existing "-quoth" argument. It has made playing AD or Copper map releases so much nicer; just bang them into their own gamedir and away you go. No manual file merging, no mixing of savegames, easy cleanup/uninstall.

I realize this is probably not the right way to do it as a general feature for public consumption. FTE for example has a generalized "-basegame" feature that seems to work for this purpose.

I don't want to relitigate "well then just use FTE" here -- often I do, there are reasons why sometimes I (or others) don't -- that's old ground and in any case Quakespasm will continue to be popular for a long time. I'm posting here just from general curiosity about whether there's a gotcha that has prevented this sort of feature from showing up in Quakespasm. I dimly remember some past arguments/discussions about why or why not to implement this. (Although I don't know why "-quoth" got a free pass.)

Also I'm kind of generally curious about the state of QS development and whether there's a process for contributing to it. I took a look at the Quakespasm repo on Sourceforge and there's activity, but it seems to be pretty buttoned-down as to who can open a ticket or otherwise contribute.

Anyway... if I had to enumerate the stumbling blocks that I see folks running into on reddit or Steam forums or GOG or wherever, the lack of a Mods menu would probably be #1, but this thing about needing to do file-merges to play AD or Copper maps would be somewhere in top 5. 

Here's an example of the (clean but hacky) approach of just adding "-ad" and "-copper" support:
https://github.com/neogeographica/Quakespasm/commit/d38492f24deffd765792d117292ddde6c54cc5a4

And here's an example of a feature supporting a generalized "basegame". Gets quite a bit messier because of maintaining backwards compat for other existing messy behaviors, so I'm not sure if this is actually the desirable solution, but it works for me. Described more in the commit comments:

https://github.com/neogeographica/Quakespasm/commit/5b849b3abe32809f7047b24b790b177a0a8dc60c 

Are there any chances to add vanilla-style underwater warp? Right now, Mark V is the only port I know that pulled it off. 

Where can I download SDL2 version of QuakeSpasm? The http://quakespasm.ericwa.com/job/quakespasm-sdl2/ link is dead. SDL1 does not allow you to change refresh rate and defaults to 60. 

http://quakespasm.sourceforge.net/download.htm

"quakespasm.exe" is what you run from among the files in the downloaded archive (assuming Windows). 

I somehow had managed to find the quakespasm-sdl12.exe binary in both my gamedir and a downloaded archive, but not the "quakespasm.exe" which is the sdl2 binary. 

👍 onward! 

@NightFright, vkQuake has vanilla underwater warp and is based on QuakeSpasm. It uses Vulkan for rendering. It's my main Quake port, partly because of the water. 

Could we have a command like r_drawclipbrushes to show playerclips in a similair fashion to showbboxes? 

What could cause this? It's happening with this map, and based on the first comment it got on Quaddicted, I'm not the only one. I'm really trying to understand why this is happening more than anything else.

The map loads and plays fine, but won't reload from a saved game:

Couldn't spawn server maps/_by_humankills:__0/_79____.bsp
Couldn't load map

It kind of looks to me as if the engine is unable to locate the .sav file, but I can locate it in my id1 directory. Besides, I always thought the "Couldn't spawn server" error happened if the engine can't find the .bsp in question, and not the .sav...?

It also looks as if it's trying to find the .sav in /maps instead of in id1. And why is it looking for the third line of the .sav file (as I saw when I opened the file with a text editor), instead of "s[some number].sav"? 

With another map (retrojam6_danzadan), I get this error when trying to load from a saved game:

Host_Error: ED_ParseEntity: EOF without closing brace

I assumed this meant that the .sav file ends without a "}", and when I opened it in a text editor, that was indeed the case. Why would something like this happen?

Out of curiosity, I added a closing curly brace manually to see if that would let me load the saved game, but all that did was to give me a new error message:

Host_Error: ED_ParseEntity: closing brace without data

:D

I should note I can usually load from saved games without any trouble. This weirdness is just happening with two maps (that I've noticed).
