Mastering Sub-Tick Consistency in CS2

Valve’s transition to the Source 2 engine introduced sub-tick packet reporting, which decouples shooting and movement calculations from the server tick rate. However, on PC setups with uncalibrated frame pacing, sub-tick packet polling can cause micro-stutters and perceived "floaty" mouse response during rapid flick shots.

Nvidia Reflex: "On" vs "On + Boost" Tested

Through our high-speed 1,000 FPS camera testing, we measured end-to-end click-to-photon latency on an ASUS ROG 240Hz OLED monitor:

  • Reflex OFF: 14.8 ms average input latency
  • Reflex ON: 8.2 ms average input latency
  • Reflex ON + BOOST: 6.4 ms average input latency (Keeps GPU clocks maxed even during low-action hold angles)

Optimal 2026 CS2 Autoexec Commands

Add the following parameters to your cs2_user_keys.cfg or autoexec.cfg inside steamapps\common\Counter-Strike Global Offensive\game\csgo\cfg:

// Sub-tick packet sync and sleep optimization
engine_low_latency_sleep_after_client_tick "true"
fps_max "0"
cl_crosshair_friendly_warning "0"
r_show_build_info "false"
rate "1000000"

Recommended Steam Launch Parameters

Right click CS2 in Steam > Properties > Launch Options and add: -novid -nojoy +exec autoexec.cfg. Avoid obsolete CS:GO parameters like -high or -threads, which can cause erratic thread scheduling on Windows 11 thread directors.
