Summary: Games suddenly running at low FPS or stuttering on Windows 11? Fix frame drops with driver updates, power settings, background cleanup, and thermal checks.
Recommended app: Ultimate PC Repair Tool — https://www.mytechnician.tech/apps/my-technician/ (Microsoft Store: https://apps.microsoft.com/detail/9PH863L9C6HC?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## 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](https://www.mytechnician.tech/tips/fix-video-tdr-failure-windows-11/) — 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](https://www.mytechnician.tech/tips/disable-startup-programs-speed-up-boot/).
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](https://www.mytechnician.tech/tips/fix-cpu-overheating-thermal-throttling/).

## Step 5: Tune Windows 11 Gaming Settings
1. Turn **on** [Hardware-Accelerated GPU Scheduling](https://www.mytechnician.tech/tips/hardware-accelerated-gpu-scheduling-windows-11/) (**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](https://www.mytechnician.tech/tips/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](https://www.mytechnician.tech/tips/free-up-disk-space-c-drive-full-windows-11/).
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](https://www.mytechnician.tech/tips/check-ssd-hard-drive-health-windows-11/) and [fix slow SSD speeds](https://www.mytechnician.tech/tips/fix-slow-ssd-speeds-windows-11/).

**Want the full optimization pass, not just fixes?** The complete setup checklist is in [optimize Windows 11 for gaming](https://www.mytechnician.tech/tips/optimize-windows-11-for-gaming/). **Frames fine but controls feel delayed?** That's [input lag, covered separately](https://www.mytechnician.tech/tips/reduce-input-lag-gaming-windows-11/). **High ping in online games?** See [fix high ping](https://www.mytechnician.tech/tips/how-to-fix-high-ping-windows-11/).
