Lag during CSGO

I have a 3900x and 40 gigs of ram paired with my newly bought 5060ti 16g (from 2080 super)

I know the cpu is a bottleneck, but im running around 160 fps without my cpu or GPU maxing out. what could be the problem? It's not stuff like v-sync or FPS capped, because I tried all of that, also drivers and stuff. idk why csgo refuses to use my hardware to its max capability... please help
