Start with frame rate and frame time
Input usually feels more immediate when the game produces frames quickly and consistently. Before changing Windows settings, reproduce the problem in the same scene and watch both FPS and frame time. A high average FPS with frequent spikes can still feel delayed because some inputs wait behind unusually slow frames.
Check display basics first
- Confirm Windows is using the intended monitor refresh rate.
- Use the display input and cable mode that support that refresh rate reliably.
- If the game supports exclusive fullscreen or another lower-latency presentation mode, compare it with your current mode.
- Test with overlays and recording tools closed.
A 144 Hz monitor running at 60 Hz will feel very different even if the PC renders more than 60 FPS. Always verify the actual refresh rate in Windows rather than assuming the monitor selected it automatically.
Keep the GPU from living at a hard limit
When GPU utilization is pinned near its practical maximum, render queues can become longer in some workloads. Try a sensible frame-rate cap that leaves a little headroom and compare input feel in the same scene. Do not assume the highest possible FPS is always the lowest-latency result if the frame pacing becomes unstable.
Test the peripheral path
For a wired mouse or keyboard, connect directly to the PC for testing instead of a questionable hub. For wireless devices, check battery level, receiver placement and interference. Very high polling rates can increase CPU overhead on some systems, so if a problem appears only at an extreme polling setting, compare a lower setting before changing Windows.
Background load can add inconsistency
Browsers, capture software, RGB utilities, update clients and background downloads can all add scheduling or storage work. Close nonessential applications and retest. The goal is not to permanently disable everything; it is to determine whether another process is involved.
Avoid universal registry tweaks
Many latency guides recommend large batches of registry changes, service disabling and timer modifications without measuring whether they address the actual bottleneck. Prefer changes you can explain, reverse and test. If a setting does not produce a repeatable improvement, restore the previous state.
When the display is the remaining limit
If frame times are stable, system load is under control and peripheral tests are clean, monitor response and scanout behavior can become the dominant remaining factor. At that point, compare the monitor's documented response modes and avoid aggressive overdrive settings that create visible artifacts.
