I recently got BOCW, and I have noticed that I average less than thirty fps in fullscreen. I can only play on windowed mode, which gives me a smooth 150+ fps experience. I have Radeon 5700xt, so I am reluctant to call it a hardware issue. I have the most recent driver and windows updates installed, too. I also don't have any malware on my PC, so it can't be that either. I don't lag like this in any other game or COD. Also, I should probably mention that my first game playing Cold War I was lagging (I assume I was in fullscreen) and something suddenly clicked. I went from skipping frames and on <30 fps to a standard 150+ fps gameplay in an instant. Not sure what caused this. Any help is appreciated, thank you.
