RTX3060Ti poor performance in bootcamp

Setup:

MBP 16" 2019 Base, i7, 5300m

Razer core X

Lg Ultrafine 5k

Zotac RTX 3060Ti Driver: 460.89 (latest)

Hello all, I'm having trouble getting acceptable performance from my new zotac rtx 3060ti. Previously I was using a rtx 2060 and got expected performance using loopback mode, within 10% of desktop numbers. My setup looks like: Lg Ultrafine 5k -> MBP in loopback mode. Egpu -> MBP.

 

With my new rtx 3060ti, I'm only getting +10% compared to the 2060 which translates to negligible gains in games. Performance is almost identical whether at 1080p or 1400p or 4k. I'm monitoring my gpu and cpu usage and GPU usage is always at 90%+ and CPU usage usually hovers around 50% in benchmarks so I shouldn't be CPU limited. 

RTX2060 heaven benchmark: 2100 -- 1080p extreme 8AA,

RTX3060Ti heaven benchmark: 2500 -- 1080p extreme 8AA

 

Things I have tried:

* drivers that came with the rtx 3060 with no update

* uninstall bootcamp and clean install, but yielded the exact same numbers. 

* use different thunderbolt cables

* using just the laptop monitor, no ultrafine, exact same numbers

* Limiting CPU power and unlimiting it. Exact same performance whether it's running @ 2.5ghz or 3.9ghz

Starting to think this Zotac is a POS, sadly there's not really any stock readily available for me to try a different GPU. Also don't have my desktop anymore so I can't plug in the GPU to a desktop.

Any suggestions or anyone else with a GPU similar to RTX 3060Ti can vouch for loopback performance numbers?

@theobserver, Loopback performance is not great and can differ between cards. For example, Radeon Polaris (RX 580) performs great but Navi (RX 5700) loses a lot more performance in loopback mode. This could be a similar situation.

@itsage, thanks for the insight! I saw several threads where loopback performance was only within 2%-10% of non-loopback mode in higher resolutions, still can't reach those numbers on my setup though. When I get a non-loopback external monitor/ better RTX30x0 card I'll report back on this thread with some results
