Hi there,
Most of the porting is complete.
I was pleasantly surprised by the high fill rate of its GPU.
My shader with dynamic shadows does roughly 50FPS at 1920x1080.
That is pretty amazing, if you realize how PS3 games can't do full 1920x1080p at fluid frame rates.
It seems that the Tegra3 has a higher fill rate than the PS3.
