Hi,
I just created an empty window with FPS displayed and noticed some impact the resolution has on FPS. Here some stats:
640x480: 3100 FPS
800x500: 2400 FPS
800x600: 700 FPS <- wtf?...
1024x768: 290 FPS <- WTF!?
After playing around a bit I moved the 800x600 window by grabbing the title bar and suddenly the FPS jumped to 1800, which is more the way I expect it to be. Unfortunately the 1024x768 window stays with 290 FPS max.
In fullscreen mode everything runs fine at full speed.
So, why do I need to move the window in order to make it run as fast as possible? And what's up with the 1024x768 window?
I'm running Mac OS X Snow Leopard. I already experienced this behavior when playing Altitude (also uses LWJGL).
Thank you very much in advance!
