CFW - Docked - Slow and unplayable - Please help!

[Pace]

Howdy,

Pretty new to this so please be kind!

I've recently modded my v1 switch, install was fine and smooth. However all was fine until i've tried to simply game whilst docked!

The console becomes extremely laggy, unresponsive at times and slow, It may take 3-5 mins to boot into games. but pull it off the dock and it's back to normal speed. One thing the dock mode struggles with is general settings - It appears to not update the TV - Loading a game and choosing a user it's 50/50 it'll display whilst docked on the TV - Un-dock and the user screen is already there waiting.

Docked games feel like the frame pacing is way off and they're playing at say 15-20fps?

I've searched high and low and found similar issues, but nothing has resolved my woes with docked. So my main SD card is brand new, and benchmarks fine - Averages around 100mbps - Fat32

So I'll try and answer questions before they're asked below.

Games from cart - Still the same
SD Card change - Tried a different card with the same build / fresh build
The SD Card is partitioned for emunand
Atmosphere / Hekate - multiple rebuilds, and clean installs - No change
Overclocking dock mode via Sys-clk to max avail - No change
Tried 4x docks and 3x chargers - No change
Multiple HDMI cables - All HDMI 2.1 cables - No change.
TV - It's not game mode related, but it's on game mode on an LG C1 - Also tried with another - Same.
There's no thermal throttling from the switch - The system is re-pasted with Arctic silver 5
erpt_reports - Cleared - No difference.
Aeroplane mode - On/Off - Makes no difference (Yep all nin services are blocked)
Tried in sys / emu and stock and it's still poor performance docked
Different pads / joycons - No Change

I've included a few screens, only thing i noticed when docked is higher usage on core #3

Any help or suggestions would be greatly appreciated! The switch is unplayable docked, but amazing un-docked -

Thank you.

Not sure if the dock update has anything to do with the lag?

Maybe the partition as stated in link?

Hey thanks for the reply! The docks are all just original docks - Sure they can't be updated via firmware? Just the Oled models it appears?

My issue is very similar to the linked issue - However my games do work, but the pacing is way off feels like 15-20 fps and takes looooong to load, but not as bad as the guys DBZ fighters video. For example Docked a game say takes 10 secs to load - Docked it'll take 1-2 mins

The partition - I've tried multiple SD cards with different / fresh partitions - All fat 32

It just doesn't make sense.
