It shouldn’t be necessarily running on “all hardware and all platforms”. It can be optional feature people can simply disable in game settings, same way as they disable tessellation and parallax on poor PCs. As for consoles, the new consoles that are coming out are actually more powerful than my PC so if I can get ~100 frames with SVOTI on my mainstream PC that means there’s no limitations for having real time G.I enabled on consoles as well. Still, capping PC to what consoles can do is a big mistake as PC is still collectively generating the most profits every year.
