Performance is slower than expected.

So, I am using a 2019 16" Macbook Pro, and whenever I connect my Wacom Cintq or an external 4K monitor, the Macbook just starts lagging really bad, I tried using the Wacom on an old windows laptop with half the specs of the Macbook and it was working just fine, without any lag, so I am sure it's not a Wacom problem.

Specs of the Macbook:

i9 - 8-core 2.3 GHz

16 GB ram

1 TB SSD

AMD Radeon Pro 5500M 4 GB

Can somehow tell me why this machine is acting this way, and how can I fix it?

MacBook Pro 16″, macOS 11.2
