Im afraid the game does not support your card.

Im afraid the game does not support your card.

In RivaTuner I select an option "OpenGL version string override" "1.5". After that at start there is a black screen and produces an error "...EXCEPTION_ACCESS_VIOLATION in module..."
How to install the latest driver, if in the list of supported cards isn't present FX series?
