You are correct about the RAM usage. No issue there. I did run the game in windowed mode and brought up the task manager. When the in game graph spiked I watched the processes and noticed that the CPU usage dropped dramatically (around 10) for battlefield but then went back to running around 38 to 45ish. There was nothing else that I could tell that was utilizing any of the CPU and if it did it was minuscule. Total CPU usage never exceeded 50% even with a spikes and lags. I did however fool around with the game mode on Windows 11 and I ended up turning it off and it caused the game to run smoothly for about 3 or 4 matches and then the issue came back. But even with game mode turned off now it still has those CPU spikes and then starts to lag.
Is Windows Power Plan set to High Performance? Do you notice the CPU frequency dropping, for example going from 3GHz down to 2GHz?
Since CPU usage is dropping during the spikes instead of increasing. It makes me think there's some sort of processing stall occuring. I have no idea where it's occuring (CPU, GPU, RAM) or what's causing it (EA anticheat, PC driver, game patch).
You can attempt to track down processing stalls with LatencyMon.
