(SKSE64) Havok fix

The easy and performance-friendly way to play Skyrim at 60+ FPS.

Oldrim version

[Require]:

Make sure you have the latest version of SKSE64 installed and running correctly.

[How this works]:

Skyrim's physics engine (HAVOK) is designed to run at 60 fps.

That's why it usually updates every ~16.7ms (1000ms/60fps).

If your game is running at a higher frame rate, you may experience some bugs (water splashing, water flashing, animals flying, objects moving on their own, etc.).

You can work around this by setting the "fMaxTime" value in the ini based on the frame rate - but this approach will result in performance degradation depending on the number of Havok objects around you.

That's why I made this plugin that dynamically assigns fMaxTime values ​​at runtime based on your current framerate.

This way you can have unlocked framerates without running into issues with HAVOK.

[FAQ]:

Q: If I play the game locked @ 60 FPS, do I need to?

A: It depends on your PC/mod setup. It can actually help if your PC can't hit a stable 60 FPS, but in most cases this isn't a problem with the physics engine.

This addon may help if you experience occasional physics glitches, but these glitches can also be caused by certain mods (e.g., Immersive Armors).

​ If planning to use @60 FPS or lower, make sure the HavokFix.ini setting is set to "MinFPS".

Q: Why use this plugin instead of simply changing the fMaxTime ini value?

A: For best performance, you basically want the fMaxTime value to be as high as possible (e.g. 0.0166 @ 60 FPS), yet low enough (e.g. 0.0069 @ 144 FPS) that it doesn't cause any physics or water spurts. This means you'll have to lock the framerate or work around possible performance losses. This plugin is my simple way to play at higher frame rates without any performance penalty.

[How to install]:

Simply install using your favorite Mod Manager or extract the zip file into the Skyrim game folder.

[compatibility]:

It should be compatible with most if not every mod on this site.

The only incompatibility I have is with RivaTuner Statistics Server.

Oldrim Version

[Requirements]:

Make sure the latest version of SKSE64 is installed and running correctly.

[How it works]:

Skyrim's physics engine (HAVOK) is designed to run at 60 fps.

That's why it normally updates every ~16,7ms (1000ms / 60fps).

If your game runs on higher framerates some bugs can appear (Water splash sounds, water flickering, animals flying, objects moving by themselves, etc...).

You can fix this by setting the "fMaxTime" value in your ini according to your framerate - but this method can lead to performance loss depending on the amount of Havok objects around you.

That's why I made this plugin, which dynamically assigns a fMaxTime value according to your current framerate at runtime.

This allows you to have an unlocked framerate without suffering from HAVOK's issues.

[FAQ]:

Q: Do I need this if I play @60 FPS locked?

A: It depends on your PC / mod setup. It can actually help if your pc can't reach a stable 60 FPS but in most cases it's not the physics engine's fault.

This plugin might help if you get occasional physics glitches but these can also be caused by certain mods (Immersive Armors for example).

Make sure to set the HavokFix.ini setting "MinFPS" accordingly if you plan to use it @60 FPS or lower.

Q: Why use this plugin instead of simply changing the fMaxTime ini value?

A: To get the best performance you basically want the fMaxTime value to be as high as possible (for example 0.0166 @60 FPS) while still being low enough (for example 0.0069 @144 FPS) to not cause any physics or water glitches. This means that you would either have to lock your framerate or settle with a possible performance loss. This plugin is …
