Software:

The M90 Quickstart guide points you to their website corsair.com/vengeanceM90 to download the latest version of their mouse configuration software. When downloading the software I noticed it is labeled as “Beta”. I know this is semantics, but if I am going to buy a product I prefer for the required software download to be final. This is not a slam for Corsair, but we as consumers need to speak up as we are seeing this as a more common offense with companies. They could easily reword the name of the install, because it is not mentioned in the software and with the features I used it felt like a finished product. The software is broken down into 3 tabs “Assign Buttons”, “Manage Performance” and “Manage Profiles”.

Assign Buttons:

On this tab you have the flexibility to program each of the 15 buttons with one of the special mouse options or a “Macro” of your choice. There are also some advanced options like basic commands (cut, copy, paste, cut, select all, find, print and save) or advanced commands (close window, lock PC, Open explorer, run, show desktop or launch program). With macros you can have a combination of advanced options and keyboard keys. I was impressed that the software allowed me to assign any key pressed from my keyboard (even the special media keys) into a macro.

Manage Performance:

This tab allows you to set the mouse response by allowing you to assign 4 different DPI settings per
profile. The DPI settings can be used for your typical “Low”, “Medium” and “High”. To change between
the different settings, you would have to assign at least 1buttons to switch DPI settings, or 2 for up and
down. The last DPI setting is a special “Sniper” DPI that can be activated by holding down any button
you assign as the Sniper button. Once the button is released the DPI settings returns back to the one
it was on. You can also set the report rate (1/2/4/8 ms) and desired mouse lift distance to fit your play
style. There is also a tool that allows you to measure the mouse’s surface quality under the mouse.
This gave me the idea to test different areas around me; my computer desk scored 4, the arm of my
coach and my leg 3, glass gave me a 3 but it did not track well (this is not a shock and Corsair does not
claim that it will work on glass). Every surface other than glass performed very well regardless of what
the surface quality reported giving a professional response.

Manage Profiles:

When managing profiles you can choose to have software or hardware playback. Software playback requires you to have the software installed, but allows you to have 50 profiles. Hardware profiles are recorded to the mouse but you are limited to 6 profiles, with this you get visual feedback from the mouse to let you know which hardware profile the mouse is using. To switch between hardware profiles you have to assign 1 button in each profile to switch between them or 2 for up and down, just like the DPI settings. This is not explained very well in the manual and I spent a lot of time trying to figure out why the mouse would not switch between hardware profiles. Corsair does provide a download with 11 predefined profiles. This is a nice start to give you an idea on how to configure the mouse.

One problem I had with the software would be its learning curve. I tried to use it without reading the downloadable Vengeance M90 Software Users Guide and found myself stumbling through the software until I took the time to read specific sections of what I was trying to do. Hopefully they will correct this by adding some wizards or help text for some of the not so user friendly functions in a future software version.

If you don’t like to read manuals, I did find a quick “software screencast” on their website that will help give you some of the secrets to programming the mouse.
