Sensitivity issues with Deathadder Elite

I got my new Deathadder Elite today to replace my old Deathadder 2013. I have the same DPI settings in Razer Synapse (800 DPI) as i did on my previous mouse, and the sensitivity is the same in everything except for some games. I've tried it in several different games but I've only had issues in first-person shooters, it keeps changing the sensitivity to be much lower than it's supposed to be.

Also when I alt-tab out of the game and back in again it's the sensitivity it's supposed to be for about 1 second before it goes back down again. I ran both games in fullscreen windowed mode, have restarted the games and computer several times and my razer synapse is up to date (updated today when I installed the mouse) but the issues persist.

Anyone who has come across this issue before? What can I do to try and fix it? Or should is there another site where I can ask?

Edit:

Seems to be working now, did a few things so not sure what exactly fixed the issue but I'll list it all anyway:

I deleted everything in C:Program Files (x86)Razer (except some fonts which were in use by system) and in C:ProgramDataRazer

I also went into the device manager, view -> show hidden devices and removed my previous mouse (deathadder 2013) and the deathadder elite. Restarted and reinstalled razer synapse and it works. Took a while to work it out but hopefully someone else can use this answer if they run into similar problems.

[Tutorial] How to use Blackwidow macro keys without synapse

The following tutorial will help you setup a python script that will allow you to use the macro keys on your Razer Blackwidow keyboard with programs like AutoHotKey without the need for Razer Synapse.

1. Download and install python ( i used version 2.7.13 ) Itunes.

2. Download and install libusb-win32

3. Run the libusb-win32 'filter wizard'

4. select 'Install a device filter' and click next

5. look for your Razer Blackwidow keyboard in the list of devices and click install

6. Download Pyusb

7. To install Pyusb open a command prompt window where 'setup.py' is located and run the command 'python setup.py install'

8. Download this Python script

9. Run the libusb-win32 'Test (win) Program' and open the Python script in a text editor

10. Make sure that the value of 'VENDOR_ID' is the same as 'idVendor' in the TestLibUsb window

    Jobs created with the student version are fully compatible with university network versions of SPACE GASS, but not with full commercial versions of SPACE. Space gass full version. Registration for the free trial version of SPACE GASS. The trial version has most of the features of the full commercial version, but with a 30 day expiry limit.

11. Make sure that the value of 'PRODUCT_ID' is the same as 'idProduct' in the TestLibUsb window

12. Make sure that the value of 'USB_INTERFACE' is the same as 'bInterfaceNumber' in the TestLibUsb window

13. Save and run the Python script

The macro keys on your Blackwidow keyboard should now work without the need of razor synapse and should now correspond to the following keys:

• m1 = f13

• m2 = f14

• m3 = f15

• m4 = f16

• m5 = f17

• Fn = f24

The python script will need to be run every time you unplug / plugin your keyboard or reboot your PC; however the script can be made to run on startup. Steps 10 to 13 may need to be repeated if you change the usb port your keyboard is plugged in to.
