How to speed up etqw

[czarnyckm]

UPDATE

It's look like the etqw-rthread work faster now... maybe nvidia 177.80 make a difference

'/usr/local/games/etqw/etqw-rthread' +set com_allowConsole 1 +seta com_unlock_timingMethod "1" +seta com_unlockFPS "1"  +seta com_unlock_maxfps "90" +seta com_videoRam "256" +seta r_useThreadedRenderer "2"

in 1280x1024/Normal/AF8x/all_set reach now constantly 40-80 FPS during online play (in start menu I have still 30FPS )
It is highly recommended to set cpu scheme to performance level
and V-SYNC off

My system debian-amd64 sid / NVIDIA GeForce 7800GT 256MB / Opteron 185 / 2GB RAM

Hi

I just discovered how to speed up etqw. It looks like it doesn't use it own libSDL:

# ldd /usr/local/games/etqw/etqw.x86
        linux-gate.so.1 =>  (0xffffe000)
        libSDL-1.2.so.0 => /usr/lib/libSDL-1.2.so.0 (0xf7eb8000)

Here should be a symbolic link :

ln -s /usr/local/games/etqw/libSDL-1.2.id.so.0 /usr/local/games/etqw/libSDL-1.2.so.0

and a change in the start script (etqw) from:

export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:."

to:

export LD_LIBRARY_PATH=".:$LD_LIBRARY_PATH"

after that etqw started with command:

'/usr/local/games/etqw/etqw' +set com_allowConsole 1 +seta com_unlock_timingMethod "1" +seta com_unlockFPS "1"  +seta com_unlock_maxfps "90" +seta com_videoRam "256"

in 1280x1024/Normal/AF8x/all_set reach now constantly 90-100 FPS during online play (in start menu I have still 30FPS )
It is highly recommended to set cpu scheme to performance level.

Usually you don't need to change the startup script as the LD_LIBRARY_PATH is empty by default and the dirs are stored in /etc/ld.so.conf - on newer distros this includes all conf files from /etc/ld.so.conf.d. Also often it is better when the system wide files are used.

Etqw must use it's own patched libSDL version in place of the standard one to reach performance increase.
BTW to reach the standard version performance level there are no changes needed...

*sigh*
etqw ships with 2 linux binaries

1) etqw.x86
2) etqw-rthread.x86

the 1st

ldd etqw.x86 | grep libSDL
	libSDL-1.2.so.0 => /usr/lib32/libSDL-1.2.so.0 (0xf7f65000)

Uses the system shared library. THIS version of the client is single-threaded

the 2nd
[code]
ldd etqw-rthread.x86 | grep libSDL
libSDL-1.2.id.so.0 => not found[/quote]
is statically linked against an id patched version of libSDL. They had to patch libSDL because libSDL cannot do multithreaded (needed for threaded_renderer). They released the patched to libSDL to include in some later version

The 1st should use the system libSDL, the 2nd *needs* to use the id libSDL and enable the cvar threaded_renderer

there is no sekrit performance boost



THEY also ship two bash scripts that LD_LIBRARY_PATH to etqw home directory to ensure the id's libSDL is loaded.

So the only way to really speed the game up is using Windows or stronger hardware, then? Realtime kernels did not help my computer.

Did you tried? On my system it run so fast as quake4-smp now.

The etqw-rthread.x86 on my system start one thread only and work at 60FPS.

The etqw.x86 start many threads and work with libSDL-1.2.id.so.0 at 90-100FPS. Before had I 30-60FPS only

I have tried your trick and it does not change performance in my computer; It's a pity having to lower graphics options and still get less performance and more fps drops than Windows with max quality settings.

You're rhigt.

I have tested on empty servers before... sorry about that

But on full ones I have observed that etqw-rthread work faster now

'/usr/local/games/etqw/etqw-rthread' +set com_allowConsole 1 +seta com_unlock_timingMethod "1" +seta com_unlockFPS "1"  +seta com_unlock_maxfps "90" +seta com_videoRam "256" +seta r_useThreadedRenderer "2"
