Two Gamers Same House
Others likely will offer a more effective approach, but I recall facing similar problems with Xboxes previously. My only fix then was using a different router that managed those situations better. I’m unsure if this applies to two PCs or if there are alternative solutions like forwarding ports. You might consider placing one PC in the DMZ if you’re comfortable with it, and check if it improves things, though you mentioned you already have open NATs.
