Reverse mouse acceleration

ClearlyNotNeeded shared this bug 2 months ago
Need More Information

It seems that if you move your mouse around horizontally, the faster you go, the lower your sensitivity, it's the inverse of mouse acceleration, making it mouse deceleration, I've tested this by putting my reticle on the edge of a door, then spin 360 slowly while moving my mouse right, and then move my mouse back left to the same position, and I didn't even get to see the door edge. Meaning the sensitivity was lowered? We need to have the ability to remove mouse acceleration, it feels really dirty and sluggish to play like this, absolutely awful.

I already posted the same response to this topic, but I'll post it here as well for visibility.


I have the same exact issue. This is definitely a bug, I've never experienced anything like it in any other game. It is not inverse mouse acceleration though, it's more like the game is capping the maximum turning speed.

  • This doesn't happen in the menu, it's only when turning the camera
  • Like OP said, it only affects the yaw axis.
  • It doesn't happen below a certain speed but it doesn't have to be particularly fast

Testing methodology:

I'm using the same methodology as ClearlyNotNeeded. I point the cross-hair at a point in the game, then move my keyboard against my mouse to serve as a reference point. I then move my mouse away from the keyboard quickly, I then move the mouse slowly back against my keyboard.

The cross-hair always goes past the point it started at (can be up to ~45 degrees off).

Tested with different mice:

  • Logitech G Pro Superlight
  • Logitech G Pro Superlight 2
  • Logitech MX Master 3

All three have the same problem. Unfortunately, I don't have a non Logitech mouse to test.

Other things I've tried:

  • V-Sync on and off
  • Full-screen and windowed
  • FOV set to max and min
  • Sampling rates from 250Hz to 4000Hz on the Superlight 2
  • DPI at 800 and 3200
  • Invert mouse x (in-game)
  • Different in-game mouse sensitivities (0.2, 2.0, 4.0)

None of the things I've tried have made any difference.

I hope this can be fixed soon, right now it sort of feels like what games use to simulate the character being drunk :)

I'm happy to provide more information if necessary.

Thanks for commenting, it seems this issue is only happening with logitech mice. How weird.

Hello ClearlyNotNeeded,


This issue seems to be caused by the Logitech provided software for the mice. Could you please check with non-Logitech mouse if this issue is still present for you if you have one? Note that we could not reproduce this issue internally.

We will investigate this more in depth and will update you once we find the exact cause.

Please note however, that we are full ahead with releasing the Vertical Slice 2 and as such, fix for this issue may come at a later date.

Thank you for your understanding.


Kind Regards,

Bartosz

I just tested it with a Razer Deathadder V3 Pro and I get the same behavior.

Couple of interesting things I found:

  • It doesn't happen when using free-look inside a cockpit but it does happen when controlling the grid.
  • In the debug menu under `Game Runtime` > `TickManagement`, disabling `Tick Server` or enabling `Pause Server` fixes the issue. Unfortunately, that makes everything else stop working :)

Given that this seems to only affect a small subset of players, I'm hopeful there is a simple solution. I'll keep trying stuff whenever I have time, I really want to play this game xD
