Getting very strange lag spikes at random in close range gunfights

I have a 7800x3d, 64GB Ram, 4090 FE and I turned basically all my settings to low because why not but everytime I get in a gunfight I literally start rubnber banding and lagging I even updated graphics drivers. I'm playing on STEAM if that matters? But yea anyone know why this is happening or anyon have the same problem?
