How to properly reinstall your graphics driver (DDU)
A step-by-step clean install of NVIDIA or AMD drivers with Display Driver Uninstaller if CS2 crashes, shows artifacts or loses FPS after an update.
If CS2 starts crashing, shows artifacts or loses FPS after a driver update, a clean reinstall of the driver helps.
🔧 Step 1. Preparation
Download the latest driver from the official NVIDIA or AMD website in advance.
Download Display Driver Uninstaller (DDU) from the developer's official site (Wagnardsoft).
Disconnect from the internet so Windows does not install an old driver by itself.
📌 Step 2. Remove the old driver
Boot Windows into Safe Mode.
Run DDU, choose device type GPU and your vendor.
Click "Clean and restart".
🖥️ Step 3. Install the new driver
After restarting, install the driver you downloaded.
In the NVIDIA installer choose "Custom" → "Perform a clean installation" if available.
Reconnect to the internet.
🎯 After installing
Set up NVIDIA Control Panel or AMD Adrenalin again — settings are reset.
The first CS2 launch may take longer: shaders are compiled again.
⚠️ Tip
Only download DDU and drivers from official sites. If the new driver performs worse, install the previous version the same way.
