Hell Let Loose is a very nice first person shooter multiplayer game. The gameplay is fun but can be annoying sometimes due to optimization issues on HLL. Because of that I made a guide about how to boost your FPS in Hell Let Loose.

I have compiled a few tweaks and recommended settings that can possibly increase the FPS. This tutorial will fix the issues such as spikes, freezinglaggingfps dropstutteringlow FPS while playing Hell Let Loose. Especially if you encounter massive frame drops after the Carentan map update, this guide will save you a little bit of this problem.

1) Best Graphics Settings for Hell Let Loose

You can skip this step if you don’t want to change graphics settings. These graphics settings are for PCs which close to the minimum system requirements.

If you have a good PC, you can increase the settings slightly.

Go to in-game video settings and make sure the settings are as follows.


Minimum SystemPerformance
Fullscreen ModeFullscreenFullscreen
Resolution Scale70% or 80% (!)100%
Vertical SyncOffOn
Texture QualityLowHigh
Shadow QualityMediumMedium
Anti-Aliasing MethodDisabledFXAA or Standard TAA
Anti-Aliasing QualityLowMedium
FX QualityLowLow
View DistanceHighHigh
Foliage QualityMediumMedium
Postprocess QualityMediumMedium
Motion BlurOffOff

Apply settings.

(!) Keep in mind! If you set the resolution scale to 70% allows to increase your FPS but the graphics will be blurry in the game.

In the meantime, lowering the FOV (Field of View) in the Gameplay Settings menu will increase your FPS slightly. You should also set the "Dead Bodies Despawn Delay" to "0.5 min".

  • You forgot to mention you can get an FPS boost by:

    Open nvidia control panel > manage 3D setting > global settings > shader cache - turn off.

    you can restart but don't need to but then go to:

    *Your Drive here*:\ProgramData\NVIDIA Corporation\NV_Cache

    & delete all the files, if you can't it might tell you there is another program using some that you can't delete, so start task manager end the processes that is stopping you from deleting the last.

    then go back to the nvidia control panel > manage 3D settings > global settings > shader cache - turn it back on
