Not getting full eGPU usage from Adobe?

I have a 2013 mac pro and I have it hooked up to OWC Helios FX 650 + Radeon RX 580. I used purgewrangler and got it all running. My question is, is there a way to manage it beyond plug and play right now? I am on osx 10.15.1 and can get photoshop and premiere to use the eGPU but the performance is worse than the internal D500. Times are longer and they lag. When I benchmark them I can get full usage from the AMD, but in premiere, it wont go past 10% usage.  Any ideas? thanks in advance

Is your display plugged to the eGPU directly?

That might affect the performance of realtime preview, should make no difference for rendering.

Nope, its plugged into the mac. If I plug it into the eGPU, it doesnt wake back up on a restart or after the screen saver kicks in. SO i leave the monitor connect to the mac. My Render times without the eGPU are 3-4 times faster. lol. I bought it just for this purpose but it slows down adobe for some reason. Even photoshop hangs and lags when using the eGPU. I feel like theres setting somewhere I am missing but I follow the directions in purgewrangler and it is working full speed in benchmarks.

Maybe try GeekBench 5 both Metal and OpenCL benchmark, to check if the computing power is fully utilized and the score is better than D500. 

If so, it could be an Adobe problem.

Having this same issue too

setup

late 2015 imac 5k i7-6700 
Catalina 10.5.1
64gb ram 
r9-390x

egpu: tb 2 > tb3
sonnet 550w + xfx rx580 8gb

I performed a geek bench test and the EGPU had a higher score Across the board, but when using adobe applications for encoding (export), photoshop, or premier pro I get slower speeds and laggy performance  compared to using the internal GPU. Glad I’m not the only one with this issue. 

sounding like this may be an adobe issue.
