[PC] A lot of shuttering using the Professional Camera

Hello, I have a RTX 4060 and a Ryzen 5600 and with everything in LOW and windowed mode with no borders, the game in Pro Cam still get shuttered a lot. My FPS is on 160-180 but everytime it drops to 70, 80, 90 and sometimes to 30 or 20 causing a lot of problems on my online matches in Pro Clubs as a Goalkeeper. I tried many many settings and no one resolve my problem, the one that really helped was change to windowed mode with no borders. Many people say that the game is bad optimized. Even using the coop camera the problem still happens, but much less. I tried most everything I see on youtube and chat gpt.
