Counter-Strike 2 Sub-Tick Mouse Stutter: Raw Input & Polling Rate Fix
Why 4000Hz and 8000Hz gaming mice cause micro-freezes in Counter-Strike 2 sub-tick netcode. Calibrate USB polling rate and Windows raw input buffers.
High Polling Rate Mice vs CS2 Sub-Tick Calculations
CS2 calculates movement and shot registration at sub-tick timestamps. When paired with an 8,000Hz polling rate mouse, the CPU must process 8,000 input interrupts every second, starving rendering threads on quad-core and 6-core processors.
Lower your mouse polling rate to 1,000 Hz or 2,000 Hz in your peripheral software (e.g. Razer Synapse or Logitech G HUB) for completely smooth frametimes.
