I mean, the path tracing lite mod was running on a 3060...do you really think the PS5 Pro is weaker? The 40fps mode is running at 1440p. We just had a game release at 840p uspscaled via PSSR2, and still have decent image quality. I really don't buy the blanket statement its not possible. I think the research and tools to attempt it aren't there yet and along with enough optimization, it can be done.
It can be done, obviously - even on base PS5. But what you have to sacrifice to achieve this?
There are mods that allows to change ray count to 1 (from 2) and reduce light bounce - this allowed AMD and older Nvidia architectures 20-40% speed bump with PT.
Unfortunately that hardware will not nearly be strong enough to make it a default, so it will always be an afterthought or a PR feature, and we`ll have a very long crossgen period anyways.
Even with all the recent ...let`s call them promises.... regarding further optimizations I´m not expecting much from PT on that kind of performance budget.
Yeah, many devs won't use it.
BUT after cross gen, it will be much cheaper just to make games with RTGI lighting/Lumen vs. baking it - and PT could be optional for quality modes (why not?). PS6 Pro will also happen at some point.
