Troubleshoot and Fix CPU and NVIDIA GPU Performance Issues in Path of Exile 2

Key Notes:

• The first time you load a map after clearing the shader cache, expect longer load times as shaders are rebuilt.
• If issues persist, consider capping FPS (e.g., 60) or switching graphics renderers (DirectX vs Vulkan).

Struggling with Low FPS and Crashes in PoE 2? How to Fix Path of Exile 2’s CPU & GPU Performance Issues

Path of Exile 2 can be demanding on your hardware, especially when it comes to CPU and NVIDIA GPU performance. If you’re dealing with stuttering, crashes, or low FPS, here’s a practical guide to optimize your system and get back to smooth gameplay.

Solution 1: Clear Shader Cache

1. Close the game.
2. Navigate to %Appdata%\Path of Exile.
3. Delete all folders named “ShaderCache.”

Solution 2: NVIDIA Control Panel Tweaks

1. Open NVIDIA Control Panel.
2. Under “Manage 3D Settings,” make these changes:
   • Shader Cache Size: Set to 100GB.
   • Power Management Mode: Switch to “Maximum Performance.”
   • Texture Filtering Quality: Adjust to “High Performance.”

Solution 3: Windows Graphics Settings

1. Go to System > Display > Graphics.
2. Add your Path of Exile executable files (e.g., PathOfExile.exe).
3. Set each file’s performance mode to “High Performance.”

Solution 4: Use NvidiaProfileInspector

1. Download NvidiaProfileInspector from GitHub and run as Administrator.
2. Select the “Path of Exile 2” profile.
3. Enable Resizable BAR (rBAR) settings:
   • rBAR Feature: Enabled
   • rBAR Options: 0x00000001
   • rBAR Size Limit: 0x0000000100000000
4. Apply changes.

Solution 5: Fix Profile Conflicts Between PoE1 and PoE2

If launching PoE2 loads PoE1’s driver profile, use NvidiaProfileInspector:

1. Remove incorrect profiles.
2. Add PathOfExileSteam.exe to the correct PoE2 profile.

Crash Mitigation Tools: PoEUncrasher

Download PoEUncrasher from GitHub. It adjusts CPU affinity during heavy loads, reducing crashes for most users.

Additional Tips for Stability

• Update your GPU drivers through NVIDIA’s official site.
• Ensure your motherboard’s BIOS and chipset drivers are up-to-date.
• Disable unnecessary background applications before launching the game.

By following these steps, you should see noticeable improvements in performance and stability while playing Path of Exile 2!
