i guess most of you kids are too young to remember the whole 3dFX bullshit and the era of original 3D accelerators - people said the same garbage you currently spout.. did that stop 3D GPUs from becoming completely ubiquitous? not by a long shot
i was thinking of 3dfx too, but more of how they kept trying to foist glide on an industry that no longer cared.
there are a lot of future trends i could see taking hold well before physics processing, like dedicated ray-tracing units. the current state of the market, with the biggest player now a subsidiary of nvidia with their tech proprietary, phyics processing is just going to stay a novelty.
i'd really like to hear it from a developer what they'd most like to incorporate into their tech.
