[archery30]

I am using a speedstarA70 video card and when i play a game the game goes dark on me and cant see well...I have all the updates for the card and it doesnt make a difference,also i went into game settings and set the the settings the best i could...Is this any where else on the pc where i can make a adjustment...We already did the display as well it didnt help either..thanks all help will be appreciated.

What game, a lot of them have console commands to increase the gamma settings.

Also in display properties, do you have a tab under settings/advanced to increase gamma or brightness.
