My monitor is 240hz and counter strike runs about 400fps max settings at 1080p on my new system. It was absolutely insane playing for the first time coming from my steam deck running 30-40fps on lowest settings.
They kind of have behind the scenes. For one they eliminated the need to bind jump throw with the console, and made it a skill check instead. A lot more visual cues as well including foot step audible distance is now shown on radar. They added a lot of little things that make the game more friendly to new players that don’t need to play for years to develop a feel for certain things.
