Need help. I have lag and choppiness using PCSX2

I have lag in games. The lag is not so bad that its unplayable, but there is definitely a choppiness and lag-delay that is frustrating. As if my system is struggling to process it, but that doesn't make any sense because I run Dolphin easily with 0 lag.

I've done lots of things. I've turned down all the graphics settings to the point the game looks like absolute garbage (and would be unplayable because of how bad it looks frankly), and there is still some choppiness. I've tinkered with settings, reset to defaults, etc, and always still that feeling of lag.

Usually at the top left corner it shows something like: Speed (100%), EE: 37%, GS: 50%, etc.

Here are my system specs:

  GFX name: NVIDIA GeForce GTX 1660 SUPER
    CPU: Intel® Core™ i5-10600K CPU @ 4.10GHz (12 CPUs), ~4.1GHz
