System latency is the time from an input reaching the PC to a visible response. Network latency affects when the server sees an action, but it is measured on a different path. Improving one does not prove the other improved.
01 · THE CHAIN
Identify which queue you are actually waiting for.
Polling, wireless interference, firmware and USB behavior affect when the PC receives the input.
The game samples input and simulates a frame. CPU stalls or a low frame rate increase the wait.
A saturated render queue can add delay between simulation and completed pixels.
Refresh rate, scanout, V-Sync/VRR choices and panel response affect when the result appears.
NVIDIA describes Reflex as a game-integrated method that synchronizes CPU and GPU rendering to reduce the render queue. That is different from forcing unrelated driver or registry settings for a game without integration.
02 · MEASURE
Turn 'feels faster' into a repeatable comparison.
- Use the same scene and FPS cap
A different GPU load changes the render queue. Keep resolution, settings and scene constant.
- Log frame behavior
PresentMon can capture frame durations and supported latency metrics; game-native latency stats are also useful.
- Repeat input samples
For rigorous click-to-photon tests, use supported latency hardware or a high-speed camera and many samples—not one click.
- Keep network separate
Record ping and packet loss, but do not add them to a local input number as if they were the same metric.
An uncapped GPU at 99% may maximize throughput while increasing the render queue. A sustainable cap, in-game low-latency technology or slightly lower GPU load can feel better even when the FPS counter is lower.
03 · SAFE ORDER
Change the closest supported control first.
| Area | Test | Trade-off to record |
|---|---|---|
| Refresh rate | Verify the intended rate in Windows and the game | Higher rate needs sustainable frame delivery |
| In-game Reflex / low-latency option | On vs off in the same GPU-heavy scene | Support and behavior vary by game/GPU |
| FPS cap | Cap below the rate the PC can hold in the target scene | Throughput vs queue depth and consistency |
| V-Sync / VRR / presentation mode | Compare tearing, latency and smoothness | There is no universal best visual/latency balance |
Also verify that the device is stable at its configured polling rate and connected as intended. Higher is not automatically better if it creates CPU overhead or intermittent behavior on a particular system.
04 · PRODUCT SCOPE
A latency label is not proof of a faster click.
crazikktweaks exposes supported system and game-profile actions with explanations and recovery context. It cannot claim a specific millisecond improvement without a controlled measurement on the target PC. Treat any action as a hypothesis, not a guarantee.
Confirm the real refresh rate, enable the game's own performance/latency stats, set a sustainable frame cap and compare one controlled scene before changing Windows.
