Ryzom on Ubuntu 10.10 64 bit

I have successfully installed and executed the client.

I have only 2 small problems (not affecting general gameplay):

1. there is a heavy sound stuttering with some effect (specifically the sound played when an animal is killed). Music and other fx sounds (ie: spell casting) play pretty well.

2. this other issue is in common with the Windows client but I never sent any ticket in the past due the fact i use in Windows the directX: with opengl ATI drivers the water is completely missing, except some glitch moving the camera. In the log file i've seen there is a failure in enabling some GLX effect, specifically related to the water.

About the sound, the only thing i tried was to force openal to use only pulseaudio, avoiding all the other engines. I also played a bit with the openal settings (in /etc/openal), with no luck.
My system sound, outside of ryzom, works pretty well, with no problems at all.

About the ATI drivers, they are the proprietary drivers bundled with Ubuntu. I tested several other 3D games, such as OpenArena, but I know there is no game around in Linux with the same complexity and demanding resources as Ryzom.
Anyway (expecially in WIndows) I never got water problems with OpenGL games (such as City of Heroes, in example).
I suppose this is related to some very old warkaround written in the code long time ago, when there were many problems with ATI opengl drivers, and never fixed because people would have used DirectX anyway (in fact, the windows client try to force the DirectX choice for ATI cards).

In linux, being opengl the only choice, I think you have to look at that old piece of code and fix it for all the linux ATI users.

I have Compiz enabled with a multitude of effects, but I didn't tried disabling it (I would prefer to have compiz enabled anyway).

My specs:

Intel Core 2 duo 2.66 (conroe)
2GB RAM
WD HD 500 GB sata 2
ATI Radeon HD4350 1GB VRAM
Ubuntu 10.10 64bit with compiz enabled
single monitor

Except from those issues, the game runs smooth at max settings and, after I moved my save folder I found everything (keyboard, macro and UI settings) exactly the same of the Windows counterpart.

The same machine runs Windows XP 32bit in dual boot.

Finally, congratulations on reaching this important step in the Linux world.

The problem is no current developer has a ATI card to experiment with :(

The OpenGL code uses a lot of OpenGL 1.x fixed functions and, at this time, nvidia and ATI were using different extensions for similar functionalities, later most of them have been unified by ARB, but parts of code would need to be recoded. And now with latest OpenGL version, a lot of extensions are deprecated in favor of shaders (which are not supported on old cards).

In OpenGL driver, there are too some workaround to fix bugged drivers (mostly for ATI), we should try to remove them and test if it works better, but again we don't have developers with ATI cards...

Anybody is welcome to tweak/test OpenGL driver on a ATI card :)

About sound, that's strange because OpenAL always worked, are you using the last version of Ryzom client ?

Ive got an ATI :)

But atm ill only have time test possible fixes/changes.

I downloaded it 3 or 4 days ago. I will check the version, to be sure it's the latest.

I could look at the code but frankly I have little free time and never seen the code extensively. I successfully built everything both in linux and windows but never started doing anything, due to lack of time (I can't even play the game atm).

I'll do some other check on my system and if I have any news about the sound, I'll post it.

Bingo !

This is a Vista/32 client.log

Got it !
driver_opengl_extension.cpp near line 1392

// In my tries ATI_fragment_shader doesn't like to be used With ARB_fragment_program (maybe a driver bug, display become corrupted)
if (ext.IsATI9500OrAbove)
{
    ext.ATIFragmentShader = false;
}

Every shader seems to work perfectly
Water :

Under Water

Clouds

Hard to say if it's was due to bugged driver or graphic cards limitation. R300 was released in 2k2 so ... :p

Thanks Naush and well done :)

As you noticed, Nevrax made some workaround which are not needed anymore :s

RE: Ryzom on Ubuntu 10.10 64 bit - Added by Naush over 4 years ago

And this is not the only one, they are several workaround in NeL for 7xx series, OpenGL driver for ATI should be flag with a big WIP ;)

Hello

I have the same problem with a Ubuntu 10.10 64bits
The water is completely missing.

Fresh compilation with the source of december, 09

I have a Intel GM 45 Express Chipset with the Intel Open Source driver.
Intel Core 2 Duo CPU P8600 2.4Ghz
4 Go of RAM
Compiz enabled
