Mouse input lag

The icons are somewhat new and show if there's low fps, packetloss etc.

If you have Origin In Game, or other gameoverlays enabled then disabling them might help you, otherwise it might be prudent to write about your problem in more detail:

Its essential to know what they show for me yo solve my problem.Does anybody know what they mean? I already uninstalled and downloaded the game and all dlc-s from scratch and the problem is still there please help .

To continue on carbonics reply i have a few questions for the OP.

1) Do you have Vsync on ?

2) Do you have a game controller or any HID Device that can count as a Mouse (But not your normal mouse that you use)

3) Does you mouse have Software (Something like Logitech Gaming Software etc)

It would be handy to have System specs and OS information to hand.

Now if you have a Gamepad plugged in, (I notice this with both the Xbox 360 Wired and Wireless that it will cause major lag/delay in mouse movements until its unplugged and then everything goes back to normal) Unplug the gamepad if it resolves the issue great.

Now if you have V-Sync enabled disable it in game to see if that helps.

If you have 3rd party software for your mouse try closing the application down before running the game(s) you have this issue with.

No, i never use v-sync in any game mainly because of the lag it makes.

No, i dont have anything usb connected to the ports except the keyboard.I dont have any problems with the mouse in other games, i play counter strike global offensive competitively and dont have any problem with the mouse.

This is the mouse http://www.x7.cn/en/product.asp?id=62 and yes it has its own drivers, its called oscar editor for changing dpi response rate and so on.

I have attached file with my pc specs.

Thanks for the System Spec, nice system BTW.

Ok i would like you to try a Mouse fix supplied by Microsoft for Windows 8.1.

It will involve regedits so i would strongly recommend that you make a back up before hand.

However if your not sure about reg edits follow these steps.

1) Open notepad (notpad++ is perfered)

2) Copy and Paste Everything under the -----  and everything above  ------x into notepad

---------------------------------

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"D:\\Origin Games\\Battlefield 4\\bf4.exe"="NoDTToDITMouseBatch"
 

------x-------x-------x---------

3) Change the Value D:\\Origin Games\\Battlefield 4\\ to where you have your game installed baring in mind that all directory levels require "\\" a double slash.

4)Now with the edit done it should look like above but with your BF4 install location, proceed to save it as a .reg file.

5) Double click new created .reg file and select merge.

6) Now press Windows key and X and select Command Prompt as Administrator and type in the following command

 Rundll32 apphelp.dll,ShimFlushCache

7) Reboot the PC and give BF4 a go again.

I have done everything you said, and tried to join some server and the problem is still there.... 

I dont know what is this ...

Have you tried testing to see if it happens on the Test Range.

When you say lag can you describe it or better still able to record it and upload it somewhere.

Classic input lag. When i move the mouse it registers it minimum 1 second later.

And the icons that i posted in the first post flicker on the right of the screen.

Just tested it on test range - same.
