nvidia fast writes

Well, my problem is with a geforce fx 5600 on a amd64 running nvidia's 64bit driver i only get 2300fps with composite extension. I am using renderaccel and nvagp, but people tell me they seem to be getting twice that. So i was wondering if anyone knew how to force fast writes. My motherboard seems to support (checked the bios, sba and fast writes are enabled), the card seems to support it (check /proc/driver/nvidia/agp/card), but its still not enabled. sba seems to work according to /proc/driver/nvidia/agp/status, but fast writes is disabled. as you can tell i'm trying to squeeze as much out of this card as possible  tongue its overclock by 77mhz...

FWs never did much for my performance.  I had some stability issues as well.


I have nothing to say, and I am saying it.

Its not going to imrpove your fps by that much. What color depth are you running? Did you comment out DRI in your xorg.conf? Remove glcore from your modules too.

Re: nvidia fast writes

Take out Option "NvAGP" "1"  OR Change the value from 1 to 3.

I get 12960 fps w/ glxgears on my 6800 GT.
By adding in Option "NvAGP" "1" it brought my speed down to 7900.

Let me know how this goes for you.
