AMD Radeon Navi GPU

[Siftah]

Type: GPU, VRAM: 18 MB, Vendor: AMD (0x1002), Device ID: 0x731f, Revision ID: 0x00c1, Resolution: 2880x1700.

This is showing that you were booted *without* acceleration.

You can still boot with the card even when it's not accelerated, if you're booted with acceleration the "About this mac" screen will show "Graphics Radeon RX 5700 XT 8GB" and you'll see more info in the "Graphics/Displays" tab of system report. Under "Metal" it will state supported and the feature set. Without that, it's not being accelerated!

You can keep WEG and use boot argument. agdpm=pikera

What brand of 5700 XT are you using?

I installed Catalina with success without the 5700 installed on the system. Now that the OS is ready with the Beta 2 installed, I tried to boot with the GPU but cant pass the clover boot menu... Anyone know why? Is there any kext that I'm missing? I can boot normally with the Intel integrated..
Thank you!

Gigabyte gaming? Reference model?
Does it have dual BIOS switching?

Yes, this one:

I don't think it has any dual BIOS.

According to the above, this is rather strange.
It turns out that the GIGABYTE Radeon RX 5700 XT GAMING OC is about 15-20% more powerful than the SAPPHIRE AMD Radeon RX 5700 XT, although in reality this should not be. They should differ only in cooling efficiency and all.
