Hello all,
I have an 8800GTX with the latest drivers installed from ASUS (169.21) and Penumbra: Overture AND Penumbra: Black Plague give me the error at startup that my graphics card does not support vertex shaders. I just got these games so I would really like to play them and any help would be greatly appreciatedSmile My OS is Windows XP Pro if it helps and I did patch the games. Thank you for any help...

I have the same card and both games work flawlessly, try 174.31 drivers. And Do not touch shader options in riva tuner if you did that.
Thank you for the response. I looked at both ASUS and Nvidia for the 174.31 drivers that you noted but they are not posted for the 8800GTX, I think that it said that the driver 174.31 is for the new series 9 card. Please adviseSmile and thank you for your assistance!

If you have latest drivers and it still does not work:
Uninstall drivers, reboot, install drivers again.

Thank you for the info...I did uninstall the games/re-install them and patch them also and I'll do the drivers again (this would be the second time however) but maybe fortune will smile on meSmile I'll let you know how things work out...
