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.

You need to profile your binaries to find out where they spend most of their cpu time and try and optimise those areas with more efficient code before you even consider micro optimisations like asm for specific cpus. Considerations like algorithm choice and cache efficiency of your data will all likely have a larger effect.

Sadly the virtuous circle of profits being put back into research and development seems badly broken in so many business now.
