Quick Answer

The fix for Wi-Fi 7 router low FPS is almost always software: power profile, driver version, shader cache, and Resizable BAR. Done in order, these restore a consistent 120 fps at 1440p without touching the wallet. Only a workload that still sits under 90 fps after a clean reset points to a genuine upgrade.

Start With One Repeatable Test Scene

Pick one save point or benchmark loop and run it three times with an on-screen counter before you change anything. Note the average and the 1% low; a drop from 120 fps to 90 fps at 1440p tells you whether this is a steady deficit or a spiky frame-time problem. The same scene every time is what separates a single-game quirk from a system-wide fault on the Wi-Fi 7 router.

In-Game Settings That Actually Matter

Drop the two heaviest settings first: ray tracing and volumetric/shadow quality, then add a frame cap a few frames under your refresh. Turn on upscaling (DLSS or FSR) at Quality to claw back headroom at 1440p. These changes recover most of the gap between 90 fps and 120 fps without making the picture look worse.

Thermals And Clock Behaviour

Watch GPU and CPU temperatures during your test loop; sustained throttling above the mid-80s C will cap clocks and produce low FPS. A clean dust filter, a fresh fan curve, and case airflow that pulls cool Johannesburg air through the front usually settle it. If a 9-series chip still throttles after that, a stronger cooler is the targeted fix, not a whole new platform.

FAQ

Will a clean Windows 11 reinstall fix Wi-Fi 7 router low FPS?

Often, but try the quicker steps first: a driver clean-install, the High Performance power plan, and EXPO memory usually solve it without wiping the drive. A full reinstall only helps when years of leftover software are interfering, so keep it as a last resort.

How do I tell low FPS apart from a slow display?

Run an on-screen frame counter and watch the 1% low number, not just the average. If frame-times are smooth but the screen still looks rough, the panel or cable is the issue; if the 1% low collapses toward 90 fps, it is a system fault.

Should I cap my frame rate to stop low FPS?

Yes, a cap a few frames below your monitor's refresh keeps frame-times even and stops the GPU from spiking. Pair it with G-Sync or FreeSync for the smoothest result at 1440p.
