Indeed you are right, the issue is mainly of a software nature (rather than hardware), the "system" (so to speak) that we adopt in Opensim-based simulators, in Second Life, and in viewers more generally, to achieve good quality makes even very powerful computers "suffer".
Without going into excessive technical details, just consider that in Sansar, it offers (with VSync) 60 FPS even on dated computers with all graphics options set to maximum, including reflections (mirrors with real-time reflections and many other graphic beauties).
It's precisely the system as it's designed and implemented in these metaverses (and in video games), which manages to offer the maximum for the visual experience without overly burdening computer hardware.
This is because they preload the entire scenario which is then processed in a sort of "box", so they preload the map and even if you have to move to an adjacent simulator, the transition doesn't have the cross-sim and you still have to wait for the loading of the new map. Even the cache is managed differently.
Simply to notice the immense qualitative difference (also in physics), just enter Sansar where even not very recent computers with graphics set to maximum can manage the entire scenario and dynamics within it without lag or loading problems of textures or cloud avatars.
Try it out for yourselves.
The concept of the Metaverse is now focused on user experiences of this kind, Decentraland, The Sandbox, Minecraft, Sansar, and others are all decidedly more efficient and less "heavy" for computers.
SL/OS are much more complex starting from the viewers, and therefore much heavier, for this reason PBR, Mirrors, and much more will make many computers struggle.
Honestly, PBR is not of interest to me, much less functional mirrors in OS or SL, I actually think they are useless, they provide a very nice visual experience yes, but if SL doesn't change the way it manages this through the viewer just like Sansar and the others do, even recent computers will always struggle.
That's my opinion.
In particular, what impressed me positively about Sansar is the real-time reflection on a whiteboard in an Egyptian museum, and the fact that both a very performant computer and one from 10 years ago with a 5-year-old video card returned the exact same experience.
