New Update 04/18/2020:
I uninstalled my two Radeon VII cards and reinstalled an older GTX 1060 I had available. I uninstalled the Radeon Pro drivers w DDU and installed the Nvidia card, installed the drivers, and ran some Resolve tests.
Using the same project from last time, which is booting media from an NVME SSD (pcie), I found two interesting things:
1) While using OpenCL with the Radeons, it still takes almost a minute (55 seconds) for me to get about five clips loaded up in Resolve to where I can actually play them back, but this 5.7K BRAW footage can play back in real time (23.976) with a hefty grade and TNR once all media has loaded. However, when I ran only one Radeon VII, that media loading time was reduced to about 20 seconds.
2) When I ran the same project and grade with the GTX 1060 and Nvidia Studio drivers (and CUDA), my media loads instantaneously, but my playback, as expected, runs about 6-8 fps.
So, even though I'm still getting excellent performance from the Radeons and OpenCL once all of my media loads, it is still strange and annoying that running a CUDA-enabled card vs OpenCL cards yields such wildly different results when loading a project.
Anyone have any answers here, or is this still being chocked up as an "optimization" problem on someone's end?
New Update (04/13/2020):
To get it out of the way, I'm currently running the latest AMD Radeon Pro Enterprise drivers with Resolve 16.2 (Windows 10 Pro 64bit).
Out of curiosity, I took some footage I recently shot on the Pocket 6K (BRAW 5.7K) and created a new project in Resolve and a new project in Premiere CC 2019. I imported all media into my dedicated bins, cut together a sequence, and added some minor grades. Again, all footage running on PCIE NVME SSD getting about 3000MB read and write speeds via AJA Speed Test.
Here's where the interesting things happened: When I reopened the Resolve project, it still took about 1 min for me to be able to access my media and actually play it back (1 min after opening the project). As well, there was a slight delay from my DeckLink mini monitor 4K to my reference monitor. Okay, still lagging.
When I start Premiere and open my new Premiere project with the same footage, same sequence and some minor grades, I get nearly instant access to my media and timeline, and I have very quick playback out to my monitor through the Decklink card via Premiere.
I understand that Resolve is a very large program and each primary tab has a lot of components to load, but this issue between Resolve and AMD is getting a bit ridiculous. To reiterate again, I did not have this problem while running an RTX 2070 or RTX 2080 with Resolve on the same PC.
I must also reiterate that once my media loads, I get excellent real-time playback in Resolve with very complex grades, so there's no real trouble once everything loads.
UPDATE (6/9/2019):
I'm still having strange issues here. I will post a video shortly to demonstrate, but I am still getting significant lag on all clip thumbnails (all tabs) loading, as well as all media spooling up for playback. Both the application and the media are booting from Samsung 860 EVO SSDs which have been confirmed to be operating perfectly with no errors reported and reading/writing around 500/530.
To reiterate, none of this seemed to be a problem before I switched out my EVGA RTX 2070 for my Radeon VII. I'm currently running the 19.5.2 AMD driver pack, and all other applications seem to be running smoothly aside from Resolve. All hard drives in the system have not reported any errors.
I would say that from initial application load up (which hangs on a white screen for a few seconds), it takes about 10 to 20 seconds for me to have access to any media in my viewer or record monitor, and the thumbnails take even longer to populate. The project I have been using to test this contains a small amount of media in a DNxHD format.
I'm also seeing lag when I wipe a still across the viewer for comparison. Comparing it to a friend's less powerful iMac, his viewer wipe felt smooth and fluid compared to mine.
Currently running Resolve 16 b 4, but again, these issues started on Resolve 15 when I changed GPUs.

Hi everyone,
I've run into a strange issue that I hope to fix up soon.
I recently swapped out an RTX 2070 for a Radeon VII, but I'm finding that not only do my media files, thumbnails, and Resolve tabs open more slowly now, but playback lags a little while working with fairly easy codecs and only a few basic corrections and some OpenFX like glow and sharpening.
I used DDU to fully uninstall Nvidia drivers from my computer and used CCleaner to clean up the registry. I then installed the Radeon drivers and all seemed well. However, I did notice that my computer (which boots from SATA III SSD) takes a few seconds longer.
And then in Resolve preferences, I made sure I was running OpenCL and selected the Radeon for compute.
But, something seems to be amiss since I'm now getting slower UI performance and slower media loading. I'm also getting occasional playback stutter that didn't exist with the RTX 2070.
EDIT: I'm running AMD's 19.5.1 driver.
In addition, I fully uninstalled Desktop Video (I'm running a Decklink Mini Monitor 4K to a ref monitor) and Resolve, and then reinstalled Desktop Video and the latest version of 15 (15.3.1). This did not solve the lag issues.
My system:
Asus B350 Plus mobo
Ryzen 7 1700
32 GB Corsair Vengeance 2666mhz RAM
Radeon VII (previously RTX 2070)
Samsung SATA III boot/app drive
Kingston SATA III SSD for media
Decklink mini monitor 4K
