Hi everyone, how can i enable anti aliasing in bound in blood?

I don't think that setting is within the game. Depending on your graphics card, there should be a control panel for it. In my case I right click on my desktop and chose NVIDIA Control Panel, and that setting is in the Manage 3D Settings section. I think you would set it to Application Controlled. That's just my guess. Good luck!

Application controlled means just that--if the game has an option for AA it's controlled in-game. Since this game does not, you would manually change it in the NVIDIA Control Panel > Manage 3D settings > Program setings > select game or add it if it's not detected automatically. Then change Antialiasing mode to Override any application setting and change Antialiasing setting to what you want. I'm not sure how you can do this with ATI drivers, but it should be similar.
