Way back in the late '90s and early '00s, lots of PC games with mouse look simply drew a window behind the game and placed the mouse cursor in the center. Every frame it would measure the distance the cursor traveled from center and reset it to poll for mouse movement. This meant that your OS mouse acceleration settings directly impacted how your mouse felt in game. If you've ever had a game glitch out and show a mouse cursor stuck in the middle of the screen, this is why.
Some of us who grew up playing these games got used to using Windows with no mouse acceleration. This is because it is easier to build muscle memory without it, since a certain distance traveled with the mouse will always produce the same camera movement in game regardless of how fast the mouse was moved.
How we deal with it? I think there are three factors, at least in my case;
1: Mouse sensitivity. I run my mouse at 1600 DPI, which is 2-4x higher than your typical typical cheap office mouse. I can zip across a large display pretty quick.
2: Fine motor skills. Years of Quake and other fast paced shooters have elevated my mouse accuracy above that of your typical computer user, allowing me to function on the desktop at a high mouse sensitivity.
3: On-the-fly DPI adjustments. My mouse has buttons for cycling through a number of sensitivity presets. I set mine to have 400, 800, and 1600 DPI. When something requires high mouse precision (such as photo editing) I turn the sensitivity down.
