Install GPU into Razer Core X Chroma
Turned on laptop & logged into Windows
Plugged in using USB-C cable that came with Razer
Approve the Thunderbolt device (Always setting)
Let it install
Downloaded NVidia drivers, unzipped them, then manually updated GPU via Device Manager
1. I don't want all the crap that comes with NVidia software
Restarted PC

Note: Windows disabled my 980 Ti in Device Manager once, just needed to enable it again

Benchmarks

Unigine Valley - High Settings

- Laptop monitor @ 1920x1080: ~80FPS

- LG Monitor @ 3440x1440: ~80FPS

I'll update this post with exact numbers next time I plug it in.

Comments

Mostly got this for game development with Unity, as the iGPU is pretty average.

Definitely has enough grunt now

For gaming, only playing Risk of Rain 2.

I've dropped the graphics down to ~medium on my 3440x1440 and it's playable for up to 60mins

Haven't made it further past that yet

It performs better when plugged into external monitor (guessing 25% FPS)

Issues

Stuttering / lagging is an issue for me. Mostly in Windows, and a little bit in gaming.

I've tried

- Plugging mouse & keyboard into laptop directly instead of eGPU

What to try next

- Disabling the iGPU via Device Manager (this concerns me)

- Running Windows in Extended mode instead of only the primary monitor (bit of a PITA)

Did you have issues with USB peripherals no longer working after coming out of sleep or shutdown?

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
