Help me achieve smooth graphics!

I need some help figuring out why my graphics don't feel or look as smooth as many streamers setups despite my specs being equal to or above their PC specs. Please help me figure it out.

My specs:

Processor: Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz 3.60 GHz
Monitor: LG 32GK850G
GPU: NVIDIA GeForce RTX2080
Memory: 32GB RAM
OS: Win 10 Pro
HD: Samsung 1TB SSD

Let me know if there's any other info I can provide.
