    How to build your own iMac Pro [Successful Build/Extended Guide]

    I think you and I are a minority here. It could be a software issue with Davinci Resolve... but it's frustrating to see my build blaze through h.264 to pro res... but crawl when it's the other way around. Also, the test I presented may not have been enough to see the issue. The issue is more...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    I don't have a Vega card to test. Maybe it's what I'm missing. Thanks for the test results, they are reassuring. EDIT: OpenCL performance using my RX580 is consistent but not that quick. Switching the hardware preferences to use CUDA and throwing in my 1080ti results in a much higher...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    If you can, I'd love for you to try the following: 1). Download and install a free copy of Davinci Resolve 14. Enter any credentials when prompted. It will start downloading the file immediately. 2). Open up Quick Time Player and do a 30 second screen recording. You'll have to time it...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    Could you give me a quick explanation on how to export SSDT/DSDT on the iMac Pro? I've never found reason to do this (probably should already know how). I can give you everything else for now.

    How to build your own iMac Pro [Successful Build/Extended Guide]

    Maybe someone can download the free version of Davinci Resolve 14 and test h.264 encoding? You can download sample RED footage in 4K or 8K (just google and it should pop up immediately) or just do a screen recording in Quick Time to use as test material. Nothing I'm doing is resulting in a...

    How to build your own iMac Pro [Successful Build/Extended Guide]

    I see. Yeah, maybe the Vega is doing something special that my RX580 and 1080ti aren't. Too bad I can't just buy an Vega 56/64 to test - well, at a reasonable price, that is.

    I've tried both. APFS and HFS. Doesn't seem to make a difference.

    How to build your own iMac Pro [Successful Build/Extended Guide]

    Anybody here use Davinci Resolve 14 in High Sierra? Exporting any video file to Pro Res 422 1080p/4K works fine and CPU is fully utilized, demolishing the performance of an iMac Pro (I would know, as I have the base model sitting right next to me for comparison). However, exporting to h.264 is...

    [Solved]Fixes to Get Full Acceleration on Intel HD Graphics in iMac 17.1

    I'm a bit lost. I have an Intel HD630 + GTX 1070 but I can only get Hardware Encoding when the HD630 is set as my primary display. Tried iMac 14,1, 14,2, and 17,1. My bios is set to have the iGPU display first, although I have tried to set it to PCIe first. Can you provide a clean outline the...

    10.11.0-10.11.3 Skylake Starter Guide

    How did you get your USB ports to work correctly? I have the exact same build as you and I can't get my USB ports to mount a portable USB 3.0 hard drive. The drive works fine on my Macbook Pro, so I know it's not the drive's fault.
