Lowest input lag setup for CS2

September 9, 2025 · 5 min read

Most players leave 15–30% of their performance on the table in CS2. Below is the exact order we tune systems on the bench, what each change buys you, and how to verify it instead of trusting placebo.

Kill input latency at the source

End-to-end latency is the metric that actually decides duels in CS2 — not raw FPS. Reflex/Anti-Lag, a sane FPS cap and high polling all stack here.

Enable NVIDIA Reflex (or the AMD equivalent) where supported, run your mouse at 1000Hz+ and disable any 'enhance pointer precision' acceleration in Windows.

  • NVIDIA Reflex → On + Boost (if available)
  • Mouse polling → 1000Hz minimum (8000Hz on supported sensors)
  • Windows pointer acceleration → Off
  • Fullscreen (exclusive) over borderless where the game allows it

Cap your frame rate (yes, really)

An uncapped frame rate sounds faster but produces uneven frame times and extra latency. A cap a few frames below your refresh rate keeps pacing tight.

For a 240Hz panel in CS2, cap around 234–237 FPS. On 144Hz, target ~141. Use the in-game limiter first, then the driver as a backstop.

Verify it actually worked

Never trust the average FPS number alone. Watch 1% and 0.1% lows and frame-time consistency in CS2 — that's what 'smooth' really means.

Run the same replay or aim-trainer routine before and after, capture with a frame-time overlay, and only keep changes that flatten the graph.

  • Benchmark the same scene before/after
  • Track 1% lows, not just average FPS
  • Watch the frame-time line — flatter is better
  • Change one thing at a time so you know what moved the needle
// The TL;DR
  • NVIDIA Reflex → On + Boost (if available)
  • Cap your frame rate (yes, really)
  • Benchmark the same scene before/after
