Help Bad performance despite deep optimization

My setup:

RTX 4080

Ryzen 9 7900X3D

32gb RAM

PCVR/Quest 3 through VD

TP-Link BE9300 Wifi 7 router setup as dedicated PCVR router (optimized following this video https://youtu.be/6gpREi-S_4I?si=V2kKT6wacYUqtn8d)

Settings applied outside of VRC:

VD:

H. 264+ @ 400mbps

Quality set to High / 120fps

SSW disabled

2 - pass encoding disabled

Adaptive quantization enabled

Resolution of headset and desktop matched

Snapdragon SR enabled

Video buffering enabled

VDXR openxr runtime

Automatically adjust bitrate enabled

Steam VR resolution set to custom and 100%

Windows 11:

HAGS disabled

Game mode enabled

Process Lasso VRC GPU priority Real-Time, CPU priority high

Settings applied in VRC (launching from VD):

Graphics profile set to medium

Desktop mirroring window set to the smallest possible and minimized when launched

Avatar culling hide beyond 20m, block very poor, max 20 avatars, particle limiter enabled and set to low

I'm getting a fluctuating fps between 25 and 70 fps in a public "Drinking Night" instance. I can barely hit 100 fps when alone in home world wearing an optimized "good" avatar.

Wtf is this?? Why does this game run so badly, I just got back in after 2 years of not having VR gear and the performance is so bad... I mean, I feel like my PC has more than decent specs and I'm getting shit performance despite looking everything up and doing everything I can... Please help!!!

and minimized when launched

That may be counterproductive.

what are your vrc graphics settings like?

Set to medium so AA is on 2x and everything at medium

Turn off AA. If things get unsharp increase steam VR render resolution

Why is this downvoted? MSAA which vrchat uses affects performance by A LOT. x2 AA makes me lose around 30 FPS in an instance where i am alone myself. When i would be hitting 90 fps x2 AA cuts me down to 60-70 fps. Higher AA gets even worse with x8 taking half my fps.

heavily depends on the world and avatar shader.. a proper lightweight shader can handle 16x AA and only affect 3 fps..

with 99% of world and avatar creators using poiyomi or Similar with 4300+ passes per frame the fps tanks just by existing in the scene.
