How to Fix PC Crashes in "The Witcher 3" and Improve Performance

Updated on February 27, 2019


The Witcher 3 is a great RPG made by CD Projekt that puts you in charge of Geralt of Rivia in a vast open world environment. I must say that The Witcher 3 is one of the best games I ever played and CD Projekt delivered a great PC version, but it has some issues that were reported by users. In this article I will show you how to fix some of the crashes and some tweaks in order to improve the overall performance.

Making the Game More Stable

For the PC version of The Witcher 3, there are some reports of random crashes occurring during the gameplay. Of course, some of the crashes can be hardware-related (bad RAM, overheating components). But other crashes we can do something about.

Since the game offers over 200 hours of gameplay, we need to have the best experience without crashes or instability.

In-Game Settings

Trust me when I say that certain combinations of settings in "The Witcher 3" increase the chances of crashes during gameplay. What do we need to do in order to lower the risks of instability? Try turning off V-Sync:

1. Turn off in-game V-Sync and use Nvidia Adaptive V-Sync/ Dynamic V-Sync for AMD.

2. Uncap the Framerate. Set "Maximum Frames Per Second" to "Unlimited." There is no need to limit our framerate and let GPU/CPU power go unused.

3. Set the Display Mode to "Full Screen" and not on "Borderless Window."

These three simple tweaks can improve the overall stability and make the game more responsive. If you want to use V-Sync, I recommend using Nvidia's Adaptive V-Sync for Nvidia users or Dynamic V-Sync for AMD users (by using Radeon Pro).

Turning On Adaptive V-Sync/Dynamic V-Sync

NVIDIA Control Panel Settings
NVIDIA Control Panel Settings


1. Right-click on your desktop and enter NVIDIA Control Panel.

2. Go to "Manage 3D Settings" and then to "Program Settings."

3. In the "Select a program to customize" box, select The Witcher 3 (witcher3.exe).

4. Go to Vertical Sync and select Adaptive (You need to have the in-game V-Sync turned off)

While you are still in the NVIDIA Control Panel, we can do some tweaks in order to gain some extra FPS.

1. In the Configure Surround/PhysX section of the NVIDIA Control Panel, change the Processor (in the PhysX settings) from GPU to CPU.

2. Go to Manage 3D Settings and then go to Program Settings. Here we are gonna select witcher3.exe in the Select a program to customize section.

3. After the executable for The Witcher 3 is selected, we will apply this setting.

  • The Anisotropic Filtering will be set to 16x. There are no visible frame drops when using this setting and it will make the game textures look better.
  • The Maximum Pre-Rendered Frames will be set to 1. This setting will make the game more smooth.
  • The Multi-Display/Mixed-GPU Acceleration will be set to Single display performance mode (if you have only one display).
  • The Power management mode will be set to Prefer maximum performance.
  • The Threaded optimization, Triple buffering and Trilinear optimization will be turned on

*PS: Some settings can be found and applied for AMD users via AMD Catalyst or Radeon PRO.


Radeon Pro Settings
Radeon Pro Settings

1. Open Radeon Pro and then add a profile for Witcher3.exe by pressing on the "+" icon marked in the photo.

2. Go to the Tweaks tab on the right and then select the Dynamic option on the VSync Control.

3. You can also enable Triple-Buffering.

Config Files Tweaks

We can tweak some values in the configuration files for more stability and performance improvements.


1. Go to The Witcher 3 Wild Hunt\bin\config\base and find resources.ini.

2. Make a backup in case you want to revert the changes made.

3. Find the line "MaxRequests: in the [ResourceLoading/Decompression] category and change it from 32 to 40. If the game is still unstable, you can try a value that will fit for your hardware (try to keep it between 32 and 40).


1. Go to The Witcher 3 Wild Hunt\bin\config\base and find rendering.ini.

2. Make a back-up for this file too.

3. Find this line: TextureMipBias. Change the value to 0.

4. Find this line: TextureMemoryBudget. Change the value from 500 to 1024.

Delete Some .dlls for Extra Performance and Stability

Yes, I know it is scary to delete dlls, but the game will not act weird if we delete some of them and we can gain some fps and stability.

1. Detele Galaxy.dll from the "The Witcher 3 Wild Hunt\bin\x64" folder. The are reports that this .dll causes some crashes. Note that after deleting it, the game will show an error, but you can press "OK" and the game will start and perform just fine.

2. Detele APEX_ClothingGPU_x64.dll from the same folder. By deleting this .dll you can gain some fps (not a lot). No errors will be shown after deleting it and the game will be a little bit smoother.

Please back up these .dlls and keep them somewhere safe, in case you want to put them back.

Some Final Words

These tweaks posted here are used by me and I played with them for over 60 hours. There are a lot of tweaks you can make (see the links at the end of this article) and you can experiment with some and see what results you have.

I only posted the ones I am using, and I know for sure that they are safe to use and have some good results.

If you have your GPU overclocked, and the game is crashing after 10-20 minutes, please revert your GPU to the stock settings. The game is quite sensible to GPU overclock. Also, update the game to v1.10, because this version has a lot of performance improvements and you can gain extra frames in some regions of the game. Please note that it takes up over 10 GB, so prepare your HDD or SSD.

Is your Witcher 3 game more stable and faster?

      I fixed the Witcher 3 freeze problem after trying everything I could possibly think of (applying any settings, game reinstall, windows reinstall, downclock, more power to GPU...). The "fix" is to remove Nvidia drivers completely and install 378.78. For AMD users - no idea. Maybe try installing drivers from 2017 too?

      You shouldn't tell people to switch Physx to CPU. In almost all cases that will slow down performance. GPU's are better at doing physics calculations by far, and the only reason to switch it to CPU would be if you had a heavily under-powered GPU but more than adequate CPU.

      Very useful tricks, buuut... the main problem is not solved, wich is the constant crashing in some locations and after cutscenes.

      The audio and controllers still functional but the image freezes until the game close itself, without a single warning.
