On linux you can do it with
nvidia-settings --query=fsaa --verbose
to get FSAA modes, then
__GL_FSAA_MODE=12 quakespasm
But it doesnt seem to work/do anything with OS X.

Gamma is working now at least it is on Squeeze.
However new bugs have cropped up in the newest build for me.I cant connect to a server ,it says connection accepted but just sits there.
Also if I try starting Single player I get this

you put some shit in your id1...

did that server work earlier? 

no spawn function for: xxx

means the map has an entity with a classname that the progs.dat doesn't have a function for.
that is to say, you are missing the progs.dat/mod for this map. 

Thanks folks
I have a modified dm2 with ent files in the maps folder.
I was using my maps folder from my SMC modded DP installation.

And yes the Gamma is working now. 

I have not yet been able to connect to a mp game.
It just sits at the console.Saying connection accepted. 

Had the same problem. You have to make sure that your router leaves the source port untouched. 

Got it to connect finally.
Runs great!The only things I do not like is it seems it does not support the chat function switches like location %l and such.
Also the chasecam is very choppy. 

is there any way to stop entities flickering when there are many being displayed at once? command line switch or something maybe? 

Tried QS for first time today (Win64). Anyone else have sound crackle issues? 

The "can't find aaaa.pcx" messages are gone, but the corresponding tga warnings are still spamming the console. 

Well, i don't know much about it, but i suppose they're occasionally useful error messages. 

I return once more :D

This time with a conundrum concerning one of my old favourite multiplayer mods - CoCoT's infamous 'Ultimate Quad Capture 1.4'! It can be found at Mod Database as the current new site is being renovated.

When accessing the menu to configure game settings, Quakespasm displays a repeat error message in the top left hand corner and some of the text gets cut off in the menu.

http://i.imgur.com/mCw0G.jpg

In the example screenshot, 10 game modes are meant to be displayed yet only 8 appear. You can still select the 10 with the appropriate key but their isn't any indication at all.

I never had this problem in Fitzquake, could it be a corrupt/odd config file?

Many thanks! 

that also happens in the menus in my rpg mod. same error message and not all the centerprint text is displayed. 

it's using the overloaded centerprint builtin, if that's any help. 

I suspect that you won't be very happy with the answer, but the problem is that there's been an overflow in the function PF_Varsting.



what?



Oh, fine then. In the regular quake code PF_Varstring uses a standard c function called strcat to combine the list of strings passed to centerprint into a buffer. strcat is a a very classic c function, and so offers no error protection. If you give it strings which are too long then it will happily overflow the buffer with them.

The standard engine code has a buffer which can hold 255 characters, but just blindly assumes that you wouldn't pass it strings that combine to a higher character count. Evidently the menu in CoCoT's mod exceeds this limit. In regular engines this overflows the buffer, which works as far as the menu is concerned but might overwrite something important in memory.

Evidently Quakespasm uses a safer function for combining strings or does some extra manual checks. The upshot is that your string gets truncated, as the error message has told you. It's hard to fault Quakespasm for fixing a bug that could potentially crash the program.

I suppose that Quakespasm could increase the size of the buffer somewhat to accomodate the mod (which has evidently been getting away with breaking the rules in other engines). It does seem best to recommend that you don't pass more than 255 characters total into centerprint, lest one day it causes memory corruption or a general protection fault. 

interesting that is actually a bug. also interesting, i tested the rpg mod quite extensively in FQ and never once experienced a crash or any kind of memory corruption. 

FQ might not have crashed because of the way the compiler used to make it into an exe reserved the static buffer used in PF_VarString(). Different brand of compilers and even different versions of the same compiler has every right to adjust such things to their liking. So, FQ never crashed is *purely* by luck. What we do in qs is not trusting our level of luck. 

does this have anything to do with needing to use -zone 2048 to prevent crashes? i recall someone on inside3d mentioning that quakespasm allocates strings differently than other engines. 

No, nothing related to -zone, at all. 

Can I request that IPlog be added for Identify please.
It would be swell to know who I am playing against. 

look at their nick name, anything else is creepy. people should have a right to anonymity through pseudonyms. 

PF_VarString's buffer has been increased somewhat in the svn repo, fixing UQC's menu. 

Are there any news about a new version of QuakeSpasm on OS X ?

I'm looking for a full support for FSAA, Vertical sychro screen redraw, and the ability to put the game into background using Command-H (as in Quake3). 

Hmmm - We need a new OS X dev. SleepwalkR and I are both busy with other things.
