Currently eGPU plugged in on top right TB3 port with a usb hub connected to the second TB3 port there. I do not need to do any tweaks in device manager to allocate resources either.
I believe I am one of those lucky guys that does not encounter much issues when getting my eGPU work in both macOS and Windows. Having said that, it means that I am happy to report that it works flawlessly!! Fingercrossed that it will keep performing normal for the days to come.
I have not yet fully tested the system but everything appears to be normal. I can keep my eGPU connected when I boot in both OS so no hot plugging or anything. I shall report bit later on my gaming experiences and other issues if that arises.[Update 13.9.21] I have been using the setup on both macOS and Windows without any trouble. The eGPU works on all 4 TB3 ports. I have not tested whether it will cause any issues if I use my Samsung T7 SSD on the same side as I only use it on the opposite side. I have played both FF14 and BioShock Remastered on both system. FF14 shows significant improvement in macOS but could not beat Windows. Bioshock is smooth on macOS but on Windows it goes up to 140fps.
macOS - Medium Setting 20fps (internal GPU) to 40fps (eGPU)
Windows - Maximum Setting 70fps
PS: I am one of those people that did not do enough research and bought a RX 6700 XT only to find that macOS does not support it. I had to return it and get the RX 6800 XT instead. Should have bought RX 6800 XT right from the start so I don't need to lose on restocking fee. I am glad it is working great now regardlessly.
