37 FPS on the Black Death track. Bad?

[Skarphol]

Hi!

I built myself a new rig in january as I could no longer wait for BOB. I built it with BOB in mind, but guess I will have to upgrade a litle bit more when it finally arrives. Anyway here are the specs of my computer:
CPU: Intel Core 2 Quad Q6600 running at 3,0 GHZ
MoBo: Gigabyte P35 DS3R
RAM: 2 Gb DDR2
VidCard: EVGA e-GeForce 8800 GTS with 320Mb DDR3
OS: Windows Vista Home Premium 64-bit

I am running Track IR 4.1

When it comes to the game itself :
V 4.091b
Video Mode: Open GL, 1280x960x32, Full Screen, Attempt stecil buffer turned on.
Video Options:
Visibilty distancs: High
Object lighting: High
Object detail: Excellent
Landscape lighting: Excellent
Landscape detail: Perfect
Cloudes detail: Detailed Cloudes

With these settings I get an average FPS on the "Black Death" ntrack of 37.
I would have expected to get far more.
Any hints to get more out of this rig?
