How to fix low FPS and stuttering

Do not buy hardware until you separate low frame rate, frame-time stutter and network lag.

Start here

Restart the PC, close unnecessary background apps, check the game’s frame cap and display mode, install the latest stable graphics driver, test lower settings, and watch temperatures plus CPU/GPU/memory usage while the problem happens.

Free checks in the right order

  1. Reproduce the issue consistently. Use the same location, settings and scene so each change is comparable.
  2. Close background work. Browser tabs, recording, updates and overlays can consume CPU, memory, storage or GPU resources.
  3. Check settings. Resolution scale, ray tracing, shadows and high-quality effects can be expensive. Confirm there is no accidental frame cap.
  4. Update safely. Use the GPU, motherboard or system manufacturer’s official support pages. Prefer a stable driver over random third-party driver tools.
  5. Watch temperatures and clocks. Performance that falls after warming up can indicate thermal or power limits.
  6. Check storage and memory. Keep reasonable free SSD space and watch whether RAM is nearly full.

When an upgrade makes sense

If lowering graphics materially raises FPS and the GPU stays heavily loaded, a GPU upgrade is a reasonable next investigation. If graphics changes barely affect FPS, inspect CPU limits. If memory is full or games run from a mechanical drive, RAM or SSD improvements may solve the specific problem for less money.

Avoid one-click “optimizer” claims

Tools promising a universal FPS boost can change settings without explaining the tradeoff. Make one reversible change at a time. Do not disable security features or install drivers from unknown sources for a tiny claimed gain.
