I have no experience with OSG, but I've been assigned to fix an issue we're having when running our OSG powered games that only happens when running on an ATI card. Time is an issue, so I'm asking the question up front instead of waiting until I'm familiar with OSG, in case it rings any bells with anyone. Our games are 2D and use lots of animations that are created by loading a large composite image as a texture with each frame of animation defined by specific u,v coordinates. To play the animation, the texture coordinates are simply changed to the desired frame of animation. Everything runs fine on nVidia cards. On ATI cards, the first time a specific animation is displayed on the screen, it pauses for a long time as if it was loading something. After that, the animation will always play smoothly. This ONLY happens on ATI cards. Does anyone have any ideas or questions? I just started looking at the code, so I should be getting more familiar with OSG shortly. Thanks.
