MacOs High Sierra - extern GPU

Hello!

The new MacOS High Sierra can take advantage of extern GPU. Anyone got the chance to test it ? Does it speed up CaptureOne ?

I am using a trusty (with ports and RAM slot!) MBP 2012 and I do not wish any of the new MPB. An external GPU could refresh the MPB performances.. especially for big export in C1 (and for video work as well, but with DaVinvi Resolv).

Thanks
Regards

  As we have done no exhaustive tests on egpu, this is to be taken as is, and does not mean that it is officially supported nor unsupported.
  
  We have run tests on TB3 on the MBP’s running 10.13.0, using AMD GPU’s, and gives a significant boost.
  However, if using egpu, be sure to disable the internal gpu’s, if the egpu if very fast. Otherwise the internals gpu’s Can slow down processing. When to disable? Take look at the benchmarks in the ImgCore.log. If there more than 4-5x times difference, between the slowest and the egpu, disable the internal gpu’s (or at least the slowest one).

  That sounds very promising...
  Any plans on officially supporting eGPUs in C1 in the near future?

  Hi Christian,
  
  I'm using egpu with Nvidia P2000 on a mid 2012 Mac mini - how can I tell if C1 uses Nvidia for OpenCL or not? I use 10.12 which has decent speed, but on 10.13 I noticed lower performance and lag.
  
  Would be nice to have this article (https://www.phaseone.com/en/Search/Arti ... cleid=1720) updated too, 2014 info in 2018 is not very useful.
  
  Cheers
