Windows 8.1, the big unknown which was awaited by millions of disappointed Windows 8 users. 8.1 brings a lot of changes the same to interface as to functionality of new Microsoft’s OS as well. For gamers it brought DirectX 11.2 which is not supported by many games in this moment but with these which support it it gives a lot of improvement. Windows 8.1 from gamers’ point of view is not only positives but it also gives new problems with games, one of the most irritating is weird mouse support. With some games your mouse can be  undetected and as you may figure out mouse will not work with some games. If you are user of Windows 8.1 and you are facing any problems with mice in any game there is few possible solutions to it.
1. Await for mouse driver update, but this “solution” works only if you have a good mouse from decent manufacturers like Razer, MadCatz, etc because they are providing any drivers for mice.
2. If you have mouse from decent manufacturer, you had Windows 8 with installed driver for your mouse and performed OS upgrade from 8 to 8.1 you should reinstall your mouse drivers.
3. If previous two solutions doesn’t apply to you or they didn’t work there is only last chance to make mouse work in the game. Go into game’s folder, find its main .exe file, right-click on it, select “Properties”, go to tab “Compatibility” and… set compatibility to Windows 8 or Windows 7, also not bad idea would be to check boxes “Disable display scaling on high DPI settings” and “Run this program as an administrator”. Click also button “Change settings for all users” and repeat all these checks in there as well.
Now game should work fine and you should be able to control it with mouse.
