As the Alpha kits were a small fraction of what the full machine is capable of, then of course theres a big leap in what can be achieved on the final hardware. Most developers will immediately start to use the multi-threaded processors (which the Alpha kits didnt have) and all the shaders, meaning that in all areas of the game, better results can be achieved. PGR3 hardly ran on Alpha kits, even when we tried to simply view the city geometry alone, but runs just fine on the final hardware with everything switched on! And because theres a lot to learn, theres plenty of power left for the games to get better and better over the generations, as the developers get to grips with the machine!
