Sluggish mouse movement
Does the mouse cursor feel sorta sluggish? It feels really delayed in moving around and makes the game feel like its running at a lower framerate. A raw input function would be nice

I've tried everything to fix this and cant figure it out, especially because it's not consistent. Turning v-sync off and on again helped, but then it came back. Changing from full screen to windowed helped, but then it came back again. Sometimes in-game it's fine, but then going to a menu or the map and back again will re-initiate terrible input lag / desync between the mouse and cursor, like the cursor is always a fraction of a second behind.

Did not you try to adjust it in game settings for your liking?

Has anyone found a solution? The game is literally unplayeable withe the mouse delay/lag...

Bringing this back from the grave. Has anyone found a fix for this?

Same problem here, anyone?

No fix yet? I just bought the game. It’s April fools today and this game feels like a joke. Sometimes it feels like it doesn’t matter how much research I do before purchasing a game something like this always pops up immediately after I buy it.

its not too bad. if anything graphics setting too high can make it worse.
The mouse does have drift or delay. but its in game files. unless someone can access it it cant get fixed. devs need to give us modding tools.

Hi everyone,

I’ve been experimenting with some tweaks to the Engine.ini and Input.ini files to improve input responsiveness and reduce mouse issues. These changes might help, so I thought I’d share them here. Let me know if they work for you!

Engine.ini Tweaks
You can find the file here:
%LOCALAPPDATA%\ASF\Saved\Config\WindowsNoEditor\Engine.ini

Add this at the bottom:
[/script/engine.renderersettings]
r.OneFrameThreadLag=0

What it does: This disables the default frame buffering, which can improve input latency.

Input.ini Tweaks
The file is located here:
%LOCALAPPDATA%\ASF\Saved\Config\WindowsNoEditor\Input.ini

Add these lines:
[/script/engine.inputsettings]
bEnableMouseSmoothing=False
bEnableFOVScaling=False
bDisableMouseAcceleration=True
bViewAccelerationEnabled=False
RawMouseInputEnabled=True
bDisableMouseAcceleration=1
bViewAccelerationEnabled=0
RawMouseInputEnabled=1

What they do:
bEnableMouseSmoothing=False: Disables mouse smoothing for precise input.
bEnableFOVScaling=False: Keeps the mouse speed consistent, regardless of FOV.
bDisableMouseAcceleration=True: Turns off mouse acceleration for better control.
bViewAccelerationEnabled=False: Disables view acceleration to reduce input lag.
RawMouseInputEnabled=True: Processes raw mouse input directly.

A Few Notes:

Make sure to back up your files before editing.
These tweaks worked for me, but results might vary depending on your setup.
If anyone else tries these changes, I’d love to hear how they work for you! Let’s help each other get the best experience possible. 😊 Oh and make the files "read only" just to be sure

Just picked up this game on a steam sale. Launched game. Immediately thought WTF is up with the mouse!? What dev team would allow this kind of lag and input delay? How'd this even get past QA?

Came searching for answers. Found this thread.

Tried the settings.

Everything worked great! Thanks so much for posting this @MaexFTW....

Just resurrecting this once more for gamepass users that found the above solution didn't work for them. I looked for the above files, which didn't exist for me so I created them and pasted the settings in, but it unfortunately didn't seem to do anything, so here's what worked for me:

I set the v-sync mode in game to ON and limited my FPS to my monitor's refresh rate. It sounds super counter intuitive, but I think the V-sync setting is bugged to do the opposite or something, at the very least it seems like it turned off the "mouse smoothing" effect, which greatly increased the responsiveness for me.

If you are looking for the files, try the following path:

C:\Users\[username]\AppData\Local\ASF\Saved\Config\WindowsNoEditor

Its not in the steam install directory, but the above, even if you've installed it on a diffrent drive. Maex's %localappdata% path should work if you copy/paste it in the address bar, but maybe the full path there might help you find it instead.

I just did the above ini edits and it worked for me.

Thanks, but again, the file just didn't exist for me. I absolutely went to the right directory but the file just wasn't there and creating it with the recommended edits just didn't make a noticeable difference for me. I don't know if it's just a gamepass side effect, but it is what it is.

Messing with the in game settings is what made the difference for me, so I hope my info can help other people in a similar boat.

Play it with a PS4 controller, it's 100000x better than playing with KB + mouse
