this is a missundestand. You dont run those games (ra2 specially) propely. You "guess" that you run it.
Please, install the windows 7 and just simple install de multiplayer Red Alert 2 from xwis.net (original server - http://xwis.net/downloads/Red-Alert-2-Multiplayer.exe) and compare the peformance with Ra2 Origin version from Windows 10.
The mouse laggy so much and The game is useless and unfair when you simple put it on windows 7.
