How to Fix Stuttering in Games on Windows (2026)

8 min read

Stutter is different from low FPS: your counter can say 200 and the game still hitches. That's because a stutter is one frame that takes far too long, and the average hides it. The fix depends entirely on the cause — so the first step is working out which one you have.

The common causes, and their fixes

1. 1

   Shader compilation

   Hitches when you see a new effect or area for the first time, especially after a game or driver update. Usually fades after a few sessions. Let games finish any 'compiling shaders' step before playing, and don't reinstall drivers constantly.

2. 2

   Background CPU spikes

   A browser tab, Discord, an antivirus scan, Windows Update or a cloud sync app briefly grabs the CPU and delays a frame. Close what you don't need, and schedule Windows Update and antivirus scans outside gaming hours.

3. 3

   Thermal throttling

   Stutter that gets worse the longer you play is the classic sign. Check CPU/GPU temperatures, clean dust out of fans and filters, and on laptops use a stand or cooling pad.

4. 4

   RAM running slow or full

   Enable XMP/EXPO in the BIOS so RAM runs at its rated speed, and close memory-heavy apps. When RAM fills up, Windows swaps to disk and games hitch.

5. 5

   Game on a hard drive

   Open-world games stream assets while you play. From an HDD that causes hitches; moving the game to an SSD fixes it.

6. 6

   Uneven frame pacing

   An uncapped frame rate swings wildly and feels choppy. Cap FPS slightly below your refresh rate, and use G-Sync/FreeSync if your monitor supports it.

Measure it: watch your 1% lows

Average FPS won't show stutter. The 1% low — the frame rate of the slowest 1% of frames — does. If your average is fine but the 1% lows are far below it, you have a stutter problem, not a raw-performance problem, and a faster GPU won't necessarily fix it.
