CS2 FPS limiter tip
CS2 players testing an in‑game FPS limiter found that capping at 400 with NVIDIA Reflex lowered temps and shaved ~1ms of input lag versus leaving FPS uncapped — a small but tangible tweak for competitive shooters CS2 FPS tip.
NVIDIA says) its Reflex tech can cut system latency by up to 35% in Counter‑Strike 2, which is the primary vendor claim players test against when changing FPS caps. Community performance guides updated this year recommend capping FPS to stabilize frametimes and drop GPU temperatures, with practical walkthroughs pointing to lower temps and quieter fans when a limiter is used. (builttofrag.com) Several pro profiles and config repositories list an in‑game max of 400 FPS (for example, ZywOo’s published CS2 profile shows a 400 max), a value that sits above common 360 Hz competitive displays while still limiting uncapped power draw. (bo3.gg) Measuring sub‑millisecond differences requires lab tools: NVIDIA’s Reflex latency telemetry and third‑party suites like CapFrameX/RTSS and MSI Afterburner are commonly used by testers to resolve ~1 ms deltas in system latency. (nvidia.com) Multiple community testers have documented interactions between CS2’s limiter and Reflex—some threads and guides show using driver or external caps and disabling Reflex (via flags like -norefIex) changes frametime stability and 1% lows, which explains why a 400 cap plus Reflex produced both cooler running and a measurable latency delta in experiments.
