Hey guys! To
@pastrychef and whoever has a Radeon VII (thanks for your help):
I'm on OpenCore 0.5.9 MacPro7,1 with 9980XE + Radeon VII. My system has no issues at all a part from a strange occurring introduced with the latests Catalina releases, no issues with 10.15.0 or Mojave.
The question is, when I cold boot my system (especially in the first minute or so) everything is laggy, even the bluetooth mouse struggles with the pointer. Things goes better after a few minutes but never super snappy. U know when all stuffs turn back super snappy? That's crazy: If I put my machine on sleep and the I wake it up... baam super fast, no kind of issue at all and stays like this for days. Then, if I reboot, it comes back laggy again.
I tried everything (with§/without RaedeonBoos kext or WEG kext) but the issue is the same.
I recently noticed the pointer issue is not occurring with a wired mouse, the general snappiness of the first minute is rubbish but the pointer doesn't lag. Then I tried using Bluetooth headset and, same here, audio hiccups at cold boot but everything super smooth after a sleep / wake cycle. I use the Fenvi T919 so it should be ok oob.
I'm asking this 'cause I dunno if this behavior is related to Vega 20 video drivers or is something linked to the bluetooth.
Any hint for troubleshooting would be greatly appreciated. Thanks.
