The SPUs can do lots of stuff, they can help a lot with regard to graphics in a more narrow perspective as well (in addition to more onscreen activity, physics and such): "One of the main developments was that more processes that were initially handled by the main CPU were being moved to the SPUs. Physics, lighting set-up, particle set-up, animation and such are by now all running on the SPU, leaving the CPU to calculate the more tricky game systems that aren't easily made parallel. At some point we even found ways to start doing certain GPU calculation on the SPUs, so now a lot of our post-processing such as bloom, depth-of-field and motion blur are being rendered by the SPUs. This freed up performance from the GPU, which in turn allowed us to go even further with shader complexity and particle density." Killzone 2 tech interviews: |
