Oh. Try cat /proc/driver/nvidia/agp/status to see if AGP really works.

Hmm. Seems largely OK. Do you have Windows to check the 3D performance there for possible hardware limitations?

WinWhat ? no, i don't have that install on this machine, just into vmware workstation, but it don't help me to check 3D performance |

yes, all for me seems ok, but 3D is very slow.
just one thing, my xorg.conf Device section is 'mimimal'
Section "Device"
Identifier "NVIDIA"
Driver "nvidia"
BusID "PCI:1:0:0"
Screen 0
Option "HWCursor" "off"
Option "RenderAccel" "True"
EndSection

nm was a problem with refreshrates, doom tried to go 640x480 and the mode wasn't configured.
However I have weird lighting artifacts, with one side of a person black and the other half much lighter, looks almost as if the lighting was reversed. |

into nvidia x86_64 faq, we can read:
| Code: |
You should also check that the correct extensions are present;
'xdpyinfo' should show the "GLX", "NV-GLX" and "NVIDIA-GLX" extensions
present. If these three extensions are not present, then there
is most likely a problem with the glx module getting loaded or it
is unable to implicitly load GLcore. Check your X config file and
make sure that you are loading glx (see "Editing Your X config File"
above). If your X config file is correct, then check the X log file
for warnings/errors pertaining to GLX. Also check that all of the
necessary symlinks are in place (refer to Appendix C).
|
pm@power64 ~ $ xdpyinfo | grep GLX
GLX
NV-GLX
i haven't NVIDIA-GLX reported ! i think i'm on good way 
i will check that deeply this evening

I don't have NVIDIA-GLX either but am getting ~4000 with GF4Ti4200 in glxgears. You might try, but I wouldn't bet for it.

i tried to put the FX5700LE 256Mo at the place of FX5900XT 128Mo and glxgears give me the same result ~1800fps
i think this PC will leave home by the window (not m$  )

Hiya! I'm thinking I'm doing something wrong here -_-;
Geforce FX5900 XT
AMD64 3200+
1GB Kingston
S-ATA
Running doom3 at 1024x768, Medium detail, default settings gives me 29.0 fps while running demo1. I know this can be higher (windows gave me 37.3 fps with high detail).
I run nvidia driver 6111 and symlinked to my own (64-bit) .so files. GlxGears gives me 7640fps.
The only thing i can think of is my driver in cat /proc/driver/nvidia/agp/status being AGPGART and Fast writes being off.
Or is this just the max i can get at this time? Is the linux version really that much slower? |

Okay...Just got Doom3 Installed. The standard how-tos at the top didn't work for me, but maybe I did something screwy. So I went the easy route and emerged the ebuild. It works anyway, and hopefully, when a patch comes out it can auto-upgrade it.
Anyway...lets see here...
AMD 3500 on Abit AV8 (via)
Geforce 6800GT 256 (woo-hoo!)
Audigy2
Pure Gentoo.
GLXgears = 12854.600 FPS
Doom3 -- timedemo demo1 = 48.8 fps. 1280x1024 and all details upped to High (but not ultra) This looks quite beautiful....if a bit dark...now where's my flashlight...
'cat /proc/driver/nvidia/agp/status'
Status: Enabled
Driver: AGPGART
AGP Rate: 8x
Fast Writes: Enabled
SBA: Enabled
(If you don't have Fast writes or SBA enabled, but want to and should be able to, edit the file /etc/modules.conf near the end...)
From what I understand, nvAGP doesn't quite work on the via chipsets (yet)... its been a while since I did the research, though. AGPGART is what-ya-got. but it does seem to work pretty well. Any hints on upping the framerate above 48?
Anyway, that's been my experience so far... I'm fairly happy.  |

I have the nForce3 250 chipset and nvAGP doesn't work. I can't build an AMD64 2.6 kernel without agpgart. |

| Posted: Thu Oct 07, 2004 2:15 am Post subject: win/lin client comparisons |
|
|
Ok, I've done some Windows/Linux comparisons here.
I've got an Athlon 64 3000+, 1G of RAM, GeForce FX 5700 with 256M RAM. I'm using the 1.0-6111 drivers, fast writes and SBA are enabled.
I ran "timedemo demo1 usecache" for 3 different resolutions in each OS, with the "high" detail setting selected, and everything default except sync to vblank disabled. I ran two trials for every resolution, and they were the same usually. They differed twice in Win.
Res. Linux Windows
640x480 28.5 39.2/39.5
800x600 20.6 29.1/29.2
1024x768 14.1 20.6
Disappointing... I don't know if its the client or the drivers. |

There's one difference between the 2 platforms that I've heard linux is a bit lacking on...Sound.
Is there any kind of sound-benchmark for linux?
Or at least you could try turning OFF sound (can we do that?) in Doom and benchmark that for comparisons...
Hmmm.... |

First mmap error, then if you use the quake3 trick, you get it complaining about a freqency of 48k rather than 44.1k.
I also tried adding the following to my /etc/modules.d/alsa to try to force it to 44.1k but no change.
| Code: | | options snd_via82xx ac97_clock=44100 |
*sigh* back to XP |
Got a solution to my problem from LinuxGames. Used this in combination with:
| Code: | echo "doom.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
echo "doomx86 0 0 disable" > /proc/asound/card0/pcm0p/oss |
From Linuxgames:
| Quote: | Solution for no sound (SNDCTL_DSP_SPEED error) - Posted by Anonymous -
Reply | Reply with History | Oct 06 2004 17:19:43 | 62.212.121.77
I see I'm not the only one to get this error:
WARNING: ioctl SNDCTL_DSP_SPEED failed to get the requested frequency 44100, got 44101
I don't have a sound server, and use pure OSS (no alsa emulation). Apparently it is caused by low-quality sound chipset, or bad drivers, that are not able to provide the requested frequency (due to limitations or round-off errors), and return the closest frequency they can handle. It should not be really an error, but Doom3 decides that for 1Hz of difference, it won't play sound :/
I propose a... radical fix: patch the doom3 binary so that it doesn't compare the returned value with the expected one, and act as if it was OK.
I don't assume any problem this could cause to your system !!
You will need a hexadecimal editor for that; I used "hexcurse" (text-mode).
- You should know where you installed doom3, and go to this directory.
- DO A BACKUP of the original "doom.x86" binary in a safe place elsewhere.
- You may need to be root to modify the file. In this case you should better do a copy of the file as a normal user, edit it as described with this user, and overwrite it back as root when you are done.Less chance to do errors as root...
- open the file with "hexcurse doom.x86"
- Go to the byte to modify by typing "Ctrl-G" and entering the address ; for doom3, it is address 001BED1B ; for doom3-demo, it is 001BE3FB.
- Modifiy the "74" under the cursor to "EB".
- Save (Ctrl-S) and quit (Ctrl-Q)
The md5sum of the modified binary is now:
a4b9c37eef2ad5142b9c88f0447bb52a for the complete version
3cb21789bd262ef6f4b451cce8559239 for the demo version.
If not, you made an error; restore the backup file and start again.
Now doom3 should ignore any difference in the frequency settings. It worked OK for me because I have only a 1Hz difference; if you have more, I don't know how it will behave...
For those interested/who want to be sure I didn't just install a virus in their binary here is the explanation:
I used "objdump -d doom.x86 > doom_disassembled.txt" to get the disassembled (machine instructions) version of the program. the SNDCTL_DSP_SPEED ioctl has for value 0xc0045002. There is only 1 occurence of this value in the code. Reading the disassembled output around leads to:
8206ce5: bf 02 50 04 c0 _______ mov $0xc0045002,%edi <-- SNDCTL_DSP_SPEED ioctl code
[... some more parameter passing ...]
8206d05: e8 1a 42 e4 ff _______ call 0x804af24 <-- call the ioctl function
8206d0a: 40 ________________ inc %eax
8206d0b: 0f 84 7e 02 00 00 ____ je 0x8206f8f <-- test if return value is -1 (error)
8206d11: 8b 4e 10 _______________ mov 0x10(%esi),%ecx
8206d14: 3b 8c 24 a4 00 00 00 _____ cmp 0xa4(%esp),%ecx <-- compare a passed parameter to a returned value (the 44100 Hz)
8206d1b: 74 24 __________________ je 0x8206d41 <-- if equal, continue code somewhere
[... else fall through the warning code and sound disabling ...]
My patch replace the test by an unconditionnal jump:
8206d1b: eb 24 _____ jmp 0x8206d41
which never cares about the comparison.
(Disclaimer: this "reverse-engineering" was done purely for interoperability purpose, so should be legal (at least here in Europe) )

Now works like a dream.. And much faster and slicker than XP

The Kernel downgrade fixed the problem for me too... overall the game runs just prfect on my machine.
I am just a little bit pissed about the Kernel downgrade, because several people, that includes me too had floppy drive problems. The device just doesn't exist.

HA-- Found the sound disable... It's
Of course, that really only raised my fps by about 1. Woop.
| Code: | | 2148 frames rendered in 43.4 seconds = 49.5 fps |
This is all with pretty high end hardware, and this would seem to indicate its still GPU limited, rather than sound. Or at least that Sound processing is taking a pretty darn small hit on my system. At any rate, This just looks too pretty to turn down any of the cool detail settings... Like I'm gonna run 640x480 in Pac-Manistropic filtering just to pop over 100 fps...SHEESH...
Ah well... Anyone know how to get surround sound functioning in Doom3?
Or does the OSS-emulation from ALSA even support it? |

Actually, you should have
127.0.0.1 hostname.domain.name localhost hostname
if you want to get domainname working correctly. Most of us do have a dyn IP too with an abstract hostname that changes from time to time. (i don't  )
