on an fpga? my geforce 2 mx and intel 915 can do almost that but you need an in kernel driver who does the actual feeding of command buffers to the gpu on an interrupt. im thinking about a buffer mapped to process memory and then composited by the card without any intervening system software. the process just tells the card when the buffer is ready. just high precision timers, no vsync and no interrupt. maybe we just need a compositing manager to tell the hardware where the the rectangles go on screen. <snipped...> _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
