Doom from 1993 is my favourite old game, ms pacman is a classic. If we're allowed to go as modern as GTA3 then Deus Ex is up there from 1999. GTA Vice City is good too, Freelancer, Dune 2000, Metal...

Trying to make a single design fit gamers and compute simultaneously is partly why AMD has struggled with GPU performance particularly on the gaming side. We've been lucky that GCN favoured compute...

AFAIK GMP is only used in non-core functions and checks (or is that Mlucas? P95 may not use it), the magic is done in hand-coded assembly. Learning ASM from scratch is a big undertaking, you will end...

Has anyone proposed the need to DC the verification step? If it's as cheap to compute as it seems it seems sensible to make that the new "don't trust a single source" step.
