So this would be like making Doom run entirely with SIMD instructions?

  Not entirely, but it sounds like you might need to rewrite parts of it in a SIMD manner to make it performant. The memory thing might be an issue, but I remember Doom was ported to the SNES which only had 128kB of RAM and a 3.5Mhz CPU. While that was a heroic hack, it leaves a lot of possible overhead for a Crey-1 port with 1 million words addressable and an 80Mhz clock.

    Well ... not quite. SNES Doom had a co-processor (SuperFX) doing the work. Even with that it had a lot of compromises to work on the hardware.

      It's also not really Doom, but an entirely different 3D engine made to run Doom level data.
