Yes, I observed an ~8% improvement in frames per second on some benchmarks. As I understand it, Y-tiling is more efficient on the GPU. I can't remember whether I tested that on Gen6 or Gen7, though. There are a bunch of people working on improving texture upload performance. It sounds like we need some faster paths for Y-tiled buffers... And perhaps we should add a new path for DrawPixels... --Ken _______________________________________________ mesa-dev mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-dev
