tnt2 glxgears (and xorg.conf) question

[belthezar]

I have just recently installed FC2 on my workstation at work that has two TNT2 cards in it. (yes I know they are older, but that's what I have to work with!) One is a Riva TNT2 and the other is an STB Velocity 4400 card. They both are setup and running with the latest nvidia binary drivers. I have X setup in a dual monitor configuration (no xinerama).

My question is that glxgears is only giving me about 60fps tops on these cards.

When running under gentoo I'm sure I was getting several hundred at least. I'm wondering if I have something incorrect in my xorg.conf that could be causing my performance to be so sucky. The nvidia driver definitely improved performance over the standard nv driver, but it seems I could go a ways further to get to what I used to have.

Any thoughts appreciated, my xorg.conf file is below.

# To disable the XKEYBOARD extension, uncomment XkbDisable.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# Or if you just want both to be control, use:
# Option "XkbOptions" "ctrl:nocaps"
