OK I need some expert in mac to troubleshoot this problem. I have the new imac 17inch screen and LOD with Carbon. I can play in the software rendering mode but I cannot play with decent fps in the openGL mode. The difference is that the software mode is not stretching the screen to the full area of the screen and runs around 30-35fps. The openGL will stretch the screen to fit the full area (the additionnal area compared with the 15inch screen is only due to the lateral length), so it is a distorted resolution, everthing is stretched to the side. However if I minimize the game into a window, it takes its right resolution and run's perfectly. I guess the game can't take the advantage of the full screen, but still I want to use the potential of the Geforce4 for a nice rendering. So question is: how can I make it run 800x600 full screen at a decent fps with openGL???
