Hi, I have been able to get the glide sdk up and running, using VC++ 4.0, but I have a problem. Whenever i'm inside a glide program in which the grBufferSwap function is used every cycle, the program takes around 5 to 10 seconds to respond to keyboard input. This happens weather i'm using directinput or windows messages. Any idea what the problem is? My comp. is PII 266 / 64M with Voodoo Banshee, so it's not just slow.
