Hi there,
I just got the ne Macbook Pro 16'' with i9 2.3 GhZ 8 Core, 32 GB Ram, 5500m 8 GB. I also got a Razer Core X with a Vega 64 (Sapphire Nitro+ 8GB).
I tested the system over some hours and while on benchmarks the performance gain with the eGPU is big, inside Davinci Resolve I'm seeing very poor results! With NR on a 4K Clip, I get 8fps - though the GPU is not even close to being maxed out, same as the GPU. Same with exporting, playback, stabilizing...the GPUs potantial is being cut down to around the same as the internal GPU. The best I get is around 35% usage of the GPU!
I understand that for Redcode the Cudas are missing, but also with BRAW or cDNG the GPU doesn't unfold its potantial. And I don't come across a CPU bottleneck (except with Redcode).
I also tried switched between Open CL and Metal without seeing a difference.
Is there something that I might be missing out or is this a software related problem?
Thanks for the help!!
Cheers
