As someone that first played BF1942 on PC decades ago and was a PC gamer exclusively, that's why I brought up PC tiers as a way to matchmake, if your on a PC but you don't have a 5090 or other God level tier PCs and getting 300 FPS in the game at this early state it may seem, like a disadvantage but it isn't, look into lowering overall latency in game.
Use the BF6 FPS counter in game under system, when turned on it will default to left upper right corner, see if your GPU or FPS is getting more FPS, if it's your GPU then go into graphic advanced settings and set to the lowest settings anything that is high CPU that will help with FPS and latency, then get a high dpi low latency mouse, use the dpi and not in game sensitivity to dial in your regular and ADS zoomed sensitivity.
The accuracy and on the fly dpi drop is a far more advantage in game than the slow reaction and low dpi resolution of controllers with aim assist, even with TMR thumb sticks, which do help, but not as much.
