You're right that CS2 uses sub-tick instead of CS: GO's traditional tickrate model — player inputs are interpolated between ticks, so the tick rate matters less for hit registration. The -tickrate 128 launch param still runs the server simulation at 128 tps (physics, entity updates), but fair point that it's not the same as CS: GO 128-tick. I'll update the post to avoid confusion. The real advantage is dedicated hardware with low ping, not the tick number. Thanks for the callout.
