How to Fix Low FPS and Stuttering in Games on Windows 11

The Problem

Games that used to run smoothly now stutter, hitch every few seconds, or sit at a fraction of their old frame rate. Sometimes it hits after a Windows update or driver update; sometimes it creeps in gradually.

Low FPS and stuttering are different symptoms with overlapping causes: consistently low FPS usually means the GPU isn't performing (driver, power, thermals), while stuttering with decent average FPS usually means something is interrupting frame delivery (background processes, shader compilation, overlays, or a struggling drive). The steps below cover both, ordered by how often they're the culprit.

Quick Checks Before You Start

1. Is the game running on the right GPU? On laptops, games sometimes launch on the power-saving integrated GPU. Check Settings > System > Display > Graphics — set the game to High performance.
2. Laptop unplugged? Most laptops halve GPU performance on battery. Plug in before judging FPS.
3. One game or all games? One game points to that game's settings or files (verify integrity on Steam); all games point to system-wide causes below.

Step 1: Clean-Update Your Graphics Driver

The number-one cause of sudden FPS loss.

1. Download the latest driver for your GPU directly from NVIDIA, AMD, or Intel.
2. If problems began after a driver update, install the previous version instead — regressions in new game-ready drivers are common.
3. For stubborn cases, do a full clean reinstall with DDU as described in fix VIDEO_TDR_FAILURE — the same procedure applies even without crashes.

Step 2: Set the Power Plan to High Performance

Windows power management can cap your CPU and GPU clocks.

1. Open Settings > System > Power & battery.
2. Set Power mode to Best performance.
3. On desktops, also press Win + R > powercfg.cpl and select High performance if available.

Step 3: Kill Background Load and Overlays

Stuttering with normal average FPS is usually interference.

1. Press Ctrl + Shift + Esc and sort the Processes tab by CPU, then by Disk. Close anything heavy — browsers with many tabs, sync clients, video apps.
2. Disable overlays one at a time and test: Discord overlay, GeForce Experience/App overlay, Xbox Game Bar (Settings > Gaming > Game Bar).
3. Trim startup programs so the load doesn't return on reboot: disable startup programs.
4. Make sure Windows isn't downloading an update mid-game — check Settings > Windows Update.

Step 4: Check Temperatures

A CPU or GPU that hits its temperature limit slows itself down — sustained FPS drops after 10–20 minutes of play are the classic sign.

1. Watch temperatures in Task Manager's Performance tab or HWiNFO while gaming.
2. GPU sustained above ~85–90°C or CPU pinned at 95–100°C means throttling.
3. Clean dust from fans and heatsinks, and check airflow — the full procedure is in fix CPU overheating and thermal throttling.

Step 5: Tune Windows 11 Gaming Settings

1. Turn on Hardware-Accelerated GPU Scheduling (Settings > System > Display > Graphics > Change default graphics settings) — helps on most modern GPUs.
2. In the same screen, enable Optimizations for windowed games.
3. Check Game Mode is on (Settings > Gaming > Game Mode).
4. If stutters started right after a Windows update, roll it back: fix Windows 11 slow after update.

Step 6: Check the Drive the Game Is On

Modern games stream assets constantly; a full or slow drive causes hitching.

1. Keep at least 10–15% of the game drive free: free up disk space.
2. If the game sits on a hard drive, moving it to an SSD eliminates streaming stutter — Steam moves games via Properties > Installed Files > Move install folder.
3. Verify the drive isn't failing or underperforming: check SSD health and fix slow SSD speeds.
