I play Apex Legends and Rocket League mainly and these games are proper lagging, RL to the point where I can't even play it. Just trying to find out why, I have built my own PC, pretty sure its nothing to do with the specs of the PC but I will put my specs below. I'm thinking it's to do with the network but I've had people out that have changed the router and all sorts but nothings sorting the problem. I never used to have any problems with lag about 6 months back, but all of a sudden its just not happy with it. Any help would be appreciated.
