How to test NVIDIA Reflex in CS2
Check whether Reflex is available on your system, then compare latency behavior with a repeatable test.
STEP 01
What the setting is for
Steam’s CS2 video-settings guidance describes NVIDIA Reflex as an option on many NVIDIA graphics cards that reduces input latency by changing when the game processes input before a frame is rendered. Its availability and effect depend on supported hardware, drivers and the rest of the system.
STEP 02
Use the in-game option first
Open CS2’s advanced video settings and check whether NVIDIA Reflex Low Latency is offered. If it is, use the game setting rather than copying a driver tweak from an unrelated guide; keep the rest of your display and graphics settings unchanged for the comparison.
STEP 03
Compare in the same scene
Record a repeatable baseline, change only Reflex, and repeat the same test. Compare responsiveness and frame pacing under the same conditions; a web page cannot measure your end-to-end click-to-photon latency or promise a fixed millisecond reduction.
STEP 04
Keep the result that fits your PC
If the option is unavailable, do not force unsupported settings. If the test produces stutters or no perceptible improvement, return to the prior state and investigate drivers, CPU/GPU limits and background load separately.
Quick checklist
- Check that the game offers NVIDIA Reflex for your hardware.
- Record a baseline with fixed resolution and graphics settings.
- Toggle only Reflex and repeat the same scene.
- Keep the setting only if your own comparison supports it.
