Penumbra: Overture Vertex Shader Error + Fix on Geforce 200 series card

[Psytronic]

Hey guys, just got Overture through the HIB pack, but immediately ran into an error reporting that my video card did not support Vertex Shaders.

Firstly, I'm running Windows XP 32-bit, SP3. My video card is a Nvidia Geforce 250 GTS. I updated my drivers to the newest version (197.45), but that wasn't an immediate fix.

To get the game working, I used the Nvidia Control Panel to create a profile exclusive to Overture, and through that set all on/off toggles to off and all other functions to "application controlled". That did the trick, and I then individually enabled/switched each function to my preferred setting whilst trying the game after applying each setting individually.

In short, the "Extension Limit" function should be switched to OFF.

If that doesn't solve your problems and you're running a similar system, try doing what I did. Create a profile for Penumbra and switch off all functions or change them to "application controlled". It's likely going to be the same issue for any of the newer Geforce series, though.
