... that thing with the splash effect... i do believe, that it iz a program issue... 3rd gen iPad haz power to burn... you can program some splashes... it's like M$ say, that, to play crysis and see the rays thru treas, you needed vista and DX 10... it turned out, that it waz a tweak, that enabled it on XP too... and i believe, if apple will implement some open standard of some physics engine, like Bullet Open Source Physics, all of the open standard devices will benefit, android and iOS alike... and nVidia physx will be not relevant... to program some separate android+nVidia version of a game? ...when there is many different android devices, that don't use Tegra? ... it could end for nVidia, like it ended for 3DFX with there glide engine... 3Dfx waz killed by OpenGL and DirectX... 3Dfx's Glide waz visually superior, but OpenGL and DirectX helped then ATi and nVidia to go multiplatform and to the masses...
... so, my point waz... prime is a nice thingy, but, if there are proprietary stuff on a open platform, like android... i don't believe, that Tegra can get some momentum without going open source... the question is... how big is the Tegra's market share on the android platform? ... and... is the market share for Tegra so big, that they can insist to use there proprietary things?...
