Ok, software versions first... 
Machine: Toshiba Satellite 1900-303
Graphics Card: ATI Radeon Mobility M6 LY
XFree 4.2.1
Kernel 2.4.20 (Gentoo sources, DRI as module, AGPGART as module)
Important parts of XF86Config:
| Code: |
Section "Module"
Load "GLcore"
Load "xtrap"
Load "speedo"
# Load "xie"
# Load "pex5"
Load "glx"
Load "dri"
Load "dbe"
Load "record"
Load "extmod"
# SubSection "extmod"
# Option "omit xfree86-dga"
# EndSubSection
Load "type1"
Load "freetype"
# Load "xtt"
EndSection

Well, my office mates here also have equal machines, and they get 100+ FPS in Quake 3 for example... While I don't get over 40... So I set out to find out why...
One thing that came to my attention was the aperture size:
modprobe -k agpgart says:
| Code: |
kernel: agpgart: Maximum main memory to use for agp memory: 203M
kernel: agpgart: Detected Intel i845 chipset
kernel: agpgart: AGP aperture is 64M @ 0xec000000
|
modprobe -k radeon says:
| Code: |
kernel: [drm] AGP 0.99 on Intel i845 @ 0xec000000 64MB
Feb 17 13:31:36 miguelduarte kernel: [drm] Initialized radeon 1.1.1 20010405 on minor 0

But X11 says:
| Code: |

(II) RADEON(0): [drm] added 8192 byte SAREA at 0xd286f000

Is it just me or X11 is really just using an 8MB aperture?
If so is there a way to force it to use the full 64MB?
Sorry for the long copy/paste... :p Just wanted to give as much information as possible.
Thanks in advance for any help.
EDIT: Also after compiling the kernel with agpgart as a module, my display shifted slightly up... :\ Don't know why since I didn't mess around with any config files... Just the kernel... Wait... I turned on Frame Buffer in the console... The console also has this behaviour... Maybe turning it off again? Gonna try that. |
