Hello my name is Daniel Hanrahan. Do you think my games should have optional calls to assembly functions for certain CPUs and GPUs in order to reach maximum possible performance and use parts/functions of the CPUs and GPUs that are not standard, but it's use for them would for tasks that is not perfect for the standard parts of CPUs and GPUs if possible, for example: instead of using the standard parts/functions of the z80 for the randomization you use the refresh register instead. Let me be clear my games have good performance.

I would argue that if your games are already performant on the platforms you care about that you would get diminishing returns. The only reason to experiment with specialist asm would be for your own experience and enrichment which is a perfectly reasonable reason to pursue it.

It's probably not worth comparing to an OS where even shaving a few cycles off of code that runs all the time on millions of computers across the world would end up with significant impact.

Thanks for the information.
