How can I get rid of it?

Have you tried this?

Ok, in the game bring up the console (~) and type preferences, that should pop out a window. Go to Rendering and Direct3D 9 Support, change SwapInterval to 0, close the window and restart the game to see if anything has changed.

That did it!! changing the value to 0 works.

I'm getting mouse acceleration in the menus (but not in-game), and this doesn't fix it for me. All it seems to do is increase the cursor speed and disable vertical sync.

[Hawk]

Sorry, I don't really know what else to suggest since I'm not affected by it. The other "solution" I've heard is to just lower the speed in the MS Windows options.

By "not affected by it," do you mean you don't experience it at all (meaning if you move the mouse quickly to one side and then slowly move it to its original position, the cursor ends up about where it started), or you do experience it but it doesn't bother you? (I'm just talking about the menu cursor here.)

[Hawk]

I've never experienced it at all, or if I have it hasn't been noticable.

So what happens if you perform the following test?

1. Make sure Deus Ex: Revision is running in full-screen mode.
   
2. Open Deus Ex: Revision's main menu.
   
3. Place the cursor at a some point of reference, such as the edge of the menu window.
   
4. Place a finger against the side of your mouse. Keep it in that spot of the surface for the rest of the test.
   
5. Quickly move the mouse to one side, but not so much that the cursor touches the edge of the screen.
   
6. Slowly move the mouse up against your finger, where it originally was.
   
7. Check where the cursor is now in relation to where it was before step 5.

With mouse acceleration, the cursor will stop short of where it started. Without it, the cursor will return to where it started, or at least close to it.

[Hawk]

Mine seems to go to where I started.

Odd that it isn't happening to you. Are you sure that the game was running in full-screen mode (windowed mode doesn't have acceleration, at least if the MarkC fix is applied), and that you moved the mouse quickly in one direction and then slowly back?

Can you get other members of the development team to perform this test?

Again, so that we're clear, I'm only talking about the menu screens, not the in-game player movement.

(And before you ask, I have disabled mouse acceleration in Windows, and I have applied the MarkC fix, which I can confirm is working.)

You'd think there'd be an option in the menus to disable it. I absolutely hate mouse acceleration.

[santi]

still happens, what a shame

[Reaxt]

never got a chance to play, this completly ruined it for me

[PolaricEntropy]

If people are still affected by this please help me out to test a mitigation we came up with a few days ago:

Just a few days ago we discovered that there is "mouse smoothing" enabled in the engine that could cause weirdness. We disabled that in hopes of mouse issues getting better (it's probably not the entire story as why input in general feels weird in Revision).

If you don't mind testing, could you please browse local files and go into Revision\System and replace Engine.u with this version and see if it feels better:

Also let me know if you feel like mouse sensitivity feels affected by this (in which case we can adjust that).

[Lucidity]

I just tried your Engine.u, it did not solve the mouse acceleration problem.
