Thanks for studying and your type phrases. I’ll be the primary to say that I’m no graphics programmer, so I can’t actually say something to the specifics and utilization of a particular characteristic. That stated, I’ll attempt to deal with your query one of the best I can. Typically, there are two core causes that we don’t make the most of particular {hardware} options that we may probably use:
First – it’s normally as a result of we’re nonetheless supporting last-gen {hardware} that doesn’t essentially have this characteristic, so we should be extra cautious about the place we spend our efficiency optimization assets. Getting last-gen performant is a a lot greater endeavor than getting current-gen performant. Spending a bunch of engineering time optimizing this characteristic that doesn’t assist our sport on last-gen consoles would possible be higher spent on discovering optimizations that assist throughout the board, particularly if the final gen nonetheless has a variety of gamers. This specific motive phases out over time, as increasingly more last-gen gamers convert to the brand new technology, but it surely’s a very huge situation within the first two or three years after the launch of a brand new {hardware} technology.
Second – it’s normally as a result of not the entire {hardware} that we’re focusing on helps that specific characteristic. The PS3 had their particular SPU Cell processors that no person else had, which meant that any work accomplished to optimize video games to run on these Cell processors was completely wasted on the PC, X360, or Wii. That is completely positive if we’re focusing on PS3 as an unique title, but it surely’s not very resource-efficient if we’re aiming on the roughly 40/40/20 cut up between PS3/X360/PC that almost all multiplatform AAA video games noticed on the time.
You most likely seen that the calculus right here is primarily “Will this effort translate to important achieve throughout all of our goal platforms?” We solely have so many graphics engineers (a few of the costliest and sought-after roles within the sport trade!) and so they solely have a lot time to work their magic. We attempt to make sure that no matter we process these people with is essentially the most environment friendly use of their restricted time. That’s the actual reply – we solely have a lot time/useful resource to spend over the course of improvement, so we attempt to get essentially the most we are able to out of what now we have.
