If you use an extended feature of a special processor, your code cannot even be transplanted to another processor of the same type (for example, AMD's 3dnow command cannot be transplanted to other Pentium series Processors ). Games written using assembler: I don't know any commercial games are fully developed using assembler. However, some games use assembler to complete most time-demanding parts. MATERIALS:
