Optimized for 32-bit?

I downloaded this neat rigid bodies demo to try out this nVidia GeForce card. It says it is “optmized for 32-bit”. This sounded cool since I thought any demo would run best in 16-bit mode.

How do you optimize for 32-bit? Is it just some OGL setting for cards that support it?

I’m guessing they mean 32 bit colour. In your pixelformatdescriptor, choose 32 bit for colour. This is assuming you are using Windows.
