FastWrite and SBA

[geovah]

I use the latest NVIDIA driver but the fast write and SBA option seems to not working :
cat /proc/driver/nvidia/agp/status
Status: Enabled
Driver: NVIDIA
AGP Rate: 4x
Fast Writes: Disabled
SBA: Disabled

The "command line" from /etc/modules.conf i use is :
alias /dev/nvidia* nvidia NVreg_EnableAGPFW=1 NVreg_EnableAGPSBA=1

So, how to use it, can it improve openGL performance ?

[mtrr]

options nvidia NVreg_EnableAGPFW=1 NVreg_EnableAGPSBA=1

on a single line should do the trick,
man modules.conf micht also help

[geovah]

I add the "option" word like you say but it is always disabled....
This option is enabled with the latest driver ?

[mtrr]

you executed depmod after editing the file?

and the driver was unloaded after executing depmod?


cheers


oh, and post the relevant part of your modules.conf

Ok, no enough time to read all of it...

But just for information,
GForce2 MX-400+ intel BX chipset = 4000 fps in glxgears.
Same configuration but replace mobo + proc + network + snd card with a nf7-s said only 800 fps.... beurk !

Under ut2003, look at http://www.tomshardware.fr/article3d.php?IdArticle=220&NumPage=5 (yes in french but i think you can understand). I have an athlon o/c to 2Ghz with busclock at 166, and i make same score...
I think glxgears is buggy ...

(I send a copy of this message to the thread you give to me)

Have nice week-end
