Set the launch parameter by right clicking the game in the Steam list and choosing "properties" and adding this.

+mat_dxlevel 95

Configure the game. After closing the game remove the launch parameter.

I have the same issue. This seems to be a common issue that Valve needs to fix asap

Let's answer two questions before we bug Valve.
What version driver have you installed?
Have you tried reinstalling your driver?

Even if it's a newer (less buggy) driver, it may not support your card. If it's horribly outdated, it may not support DirectX 9.0c. Also, by asking this question, we clear up if you have a proper driver or not.

Sometimes drivers install wrong. Once, I installed Catalyst and half of all triangles were missing. Reinstalled the driver and it worked perfectly.

Also, all your cards have DirectX 10 compatibility, so that can't be it.

I am currently running the latest driver and this has been a problem for a few driver versions. I have tried to reinstall the video driver but that did not help. Its a problem with the game not my system or its software.
