Installation steps
- 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
- 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.

I don't remember this being an issue, but I also stopped using USB & ethernet on the device because I thought it was causing stutters.
I've since sold my eGPU because bought a Ryzen desktop.
