Stop games stuttering — the 5-point checklist

Steps

1. 01

   Make sure your GPU driver is current — and clean

   • Check which GPU you have in Task Manager → Performance → GPU
   • NVIDIA: download the latest driver for your card from nvidia.com/drivers, run the installer, choose Custom (Advanced), then tick 'Perform a clean installation'
   • AMD: download the latest driver from amd.com/support and run the AMD Software installer — its clean-install option is called 'Factory Reset (Optional)'
   • Or right-click the desktop for the vendor control panel — Windows 11 needs 'Show more options' first, or launch it from the Start menu
   • If stutter survives a fresh update, do a clean reinstall with DDU (Display Driver Uninstaller): download it only from the official Wagnardsoft site, wagnardsoft.com, then run it in Safe Mode
   • Before you boot into Safe Mode: on Windows 11 24H2 your PIN may not work there, so make sure you know your account password first

   Why?

   A 'clean install' strips the old driver's settings first; half-cleaned drivers are a classic cause of stutter that survives an update.

2. 02

   Verify the game files

   • Steam: right-click the game in your Library → Properties → Installed Files → 'Verify integrity of local game files'
   • EA app: Library → three dots on the game tile → Repair
   • Epic Games Launcher:Library›three dots›Manage›Verify

   Why?

   'Verify' re-downloads anything missing or corrupted — the cheapest fix on this list.

3. 03

   Check whether the PC is throttling from heat

   • GPU temperature:Task Manager›Performance›GPU, for a dedicated card on a supported driver
   • No CPU reading in Task Manager — use a free tool like HWiNFO, from the official hwinfo.com only, or your PC maker's own utility
   • During a stuttering session watch both: clock speed dropping while temperature sits at its maximum is throttling, not a driver problem
   • Screaming fans and a hot chassis are the plain-English version — clean out dust and check airflow first

   Why?

   Throttling is the hardware slowing itself down to stay cool; it reads as random stutter because it kicks in exactly when load spikes.

4. 04

   Keep at most one overlay running

   • Steam: Settings → In-game → turn off 'In-game overlay' if you don't use it
   • Discord: open User Settings (the gear icon) and turn off the in-game overlay setting — it's usually under Activity Settings, but the name has changed between versions
   • NVIDIA app:Settings›Features›NVIDIA Overlay›turn it off

   Why?

   An overlay draws on top of the game (FPS counters, chat pings) and hooks into its frame loop — two or three at once is where stutters come from.

5. 05

   Turn off background recording (and Game Bar on Windows 10)

   Windows 11

   • Windows 11: Settings → Gaming → Game Bar has no main on/off switch — only 'Allow your controller to open Game Bar' and a controller Guide-button option — so Windows 11 has no single switch that disables Game Bar
   • Windows 11: turn off the part that affects performance — Settings → Gaming → Captures → switch off 'Record what happened', which stops the background recording

   Windows 10

   • Windows 10: Settings → Gaming → Xbox Game Bar has an on/off switch — turn it off; then Settings → Gaming → Captures → switch off 'Record in the background while I'm playing a game'

   ✓You should see: The background-recording setting shows Off — 'Record what happened' on Windows 11, 'Record in the background while I'm playing a game' on Windows 10 (where the Xbox Game Bar switch also shows Off) — and the game no longer keeps a silent rolling capture running.

   Why?

   Background recording keeps your last few minutes of gameplay in memory, running whether you use it or not. Win+Alt+R only starts a manual recording — it isn't the same thing.
