Poor video quality with Quest 3

I have a Quest 3.

My PC is an MSI Raider A18/HX A9W, a high end gaming laptop/desktop replacement. Specs include:

Processor AMD Ryzen 9 9955HX3D 16-Core Processor, 2500 Mhz, 16 Core(s), 32 Logical Processor(s)

RAM: 64GB

Graphics: Nvidia mobile 5090 (yes, I know it's actually a 5080 with more VRAM).

This runs MSFS2024 superbly in 4k on high settings. I don't expect the graphics in the Quest 3 to match it, but they are still very disappointing compared to what I've seen of users with similar hardware.

I'm using Visual Desktop with a dedicated router, a TP-Link Archer BE550 with both PC and Quest 3 connected via 6G. Yes, I use it in the same room and yes the computer is plugged into Ethernet.

Here's a sample image, showing the VD specs. https://imgur.com/a/ORSRocb

Any suggestions?
