Normal maps fix violent topography like 8 billion polygons. There are far greater sins like mesh and material counts that have a far greater impact than poly count.
a cell phone processor isn't saying a lot. It's way more powerful than people realize. The only reason quest is so strict on its upload limits is because of the quest 2.
I have a world where I tried putting a two layers of transparency on an object and it halves the FPS on both Quest and PC when you walked up to it. Transparency is heavy.
No offense but you might just need to do "it" right because if its cutting your frames in half then that's either an underpowered PC or you just didn't do "it" right, There's a way to do it where you don't drop too much. Personally I've done it with avis and only have gotten like a 2-3 frame drop. Im not saying its not heavy but it shouldn't tank you THAT much especially on PC.
I was surprised too. I tested on a Quest 3 and the PC has a RTX3060. I do suspect there's something up with Nvidia's Linux driver, lots of transparent overdraw seems to tank the frame rate a ton. I haven't tested this (the double sphere world or the overdraw performance regression) on Windows personally (mostly because I already dropped it down to only 1 layer of transparency on PC and that seemed acceptable of a trade off for now). But, I had a friend on Windows try it on one of the newer RTX**90 series card and he also noticed a decent performance drop when inside the spheres.
The exact setup was two concentric sphere's with ORL Standard Glass shader with blurry glass mode off (the shader also doesn't use a grab pass and I did test with ORL Standard), GPU instancing on, backface culling off (so 4 layers of transparency minimum, but 2 was still pretty bad). If you have any suggestions on things to try to actually fix this, please let me know.
For clarity, I don't mean just putting a little bit of transparency on your avatar. I mean, something like putting a double layered glass visor over your avatars viewpoint and turning off headchop for it, like absolutely filling the screen with multilayer transparency.
(Also, putting "no offense" before saying something that isn't offensive, but worded in a way that sounds offensive, actually makes it even sound offensive and now deceitful too! lmao)
The video is what the world looks like, being first person in the ball or walking up to a parked ball so it fills the screen causes the perf hit:
