What is wrong with my scores in Q3test (G400)?

[vplin]

I tried this timedemo 1 on my g400 and cel466 with following settings:

graphics mode custom
gl driver default
gl extensions on
video mode 1024*768
color depth 32 bit
full screen on
lighting lightmap
geometric detail high
texture detail full
texture quality 32 bit
texture filter trilinear
marks on walls yes
ejecting brass yes
dynamic lights yes
light flares yes
identify target yes
high quality sky no
sync every frame no
high quality sound on

I got only 13.7 fps in timedemo 1!!!! :-(

Should it be higher?
