Hey folks.

I just set up my first hackintosh. Yay! Actually I didn't plan to build one in the first place that's why I haven't checked out any buyer guides beforehand. (I'm running a Ryzen 7 2700X on a ASRock X570M Pro4 with a PowerColor RX 5700 XT. Bad CPU choice, I know... this was an accident as well) But I figured: Well, I just give it a try.

Using OpenCore 0.5.7, macOS 10.15.4, SMBIOS MacPro7,1 everything is running smoothly except for those micro lags and stuttering. I first experienced it on my external audio interface (Native Instruments Komplete Audio 2): Small stuttering when watching YouTube oder listening to music on SoundCloud. (Mainboard Audio is fine) But then my USB mouse and keyboard started lagging as well. When I move my pointer in a straight line it will freeze in place every couple of seconds for a few milliseconds and then jumps back to the place it should be. I can reproduce it every time I open the "About This Mac" window. It's horrible. Also the rendering and video playback performance in Safari is quite poor. I got some kind of stuttering when resizing the window. I can play and resize H264 videos in Quicktime Player smoothly without problems and VDADecoderChecker says hardware acceleration is working. DRM on the other hand is not working and I couldn't get it to work following the Open Core Desktop Guide. Also graphics performance seems a bit off... I get just around 1700 Point/40fps in Unigine Valley Benchmark on 1080p Ultra. Everything's working fine on Windows though.

I digged into USB port mapping but that doesn't seem to be an issue. All ports are recognised correctly... So I figured it might be a problem with my graphics card... But after days of looking for answers I'm stuck here.
Can you take a look at my EFI If I did something terrible wrong?

Thank you so much in advance for your help. <3

I don't know the answer here, but just curious if I have a similar issue.

Are you plugging in your usb devices directly into the mobo or are you using a USB hub?

Change your BIOS setting for the GPU to run at PCIe 3.0 and if possible, disable any com ports in BIOS and your build will run without hickups.

I have the same issue. I have read it's related to the DisplayPort settings on 5700XT. You need to turn down the DP version on your card/monitor or something. I can't remember. From what I read people running 5700XT on real Macs are having the same issue. My Ryzentosh is now just languishing because of the 5700XT card.
