Game freezes every 20–30 minutes — server issue or my PC?

I just got a new PC (RTX 5080 + Ryzen 9800X3D) and was playing on Friday night. At first, the game ran flawlessly — stable 100+ FPS at 4K — but later that night it started freezing every 20–30 minutes.

It’s not regular FPS drops. The FPS counter stays high, but the game itself locks up for a few minutes: I can’t move, and I usually end up dying.

Previously, I played on a laptop with an RTX 3070. The FPS there was much lower, but I never had these kinds of freezes.

Is anyone else running into the same issue? Is this more likely a server-side problem, or something on my end?
