PHYSX GPU displayed on screen

[Bloodbuster]

Hi

I have just got the game via Steam. After I start a new game or click continue, the loading screen displays PHYSX GPU in the top left corner. The letters PHY and S are white, whilst the rest is green.

I have the majority of the settings maxed out except for blur.

My card is a 9800 GX2 1GB, running on a Win 7 Ultimate PC with 4GB RAM and Quad core 2.66. Resolution is set to 16:10 1280x800

Anyone have any ideas what may be causing this, please?

Thanks.
