Hey man I have noticed with windows 8.1 also that this game runs reallllly sluggish, something is wrong with Origin as well, if i have it open without opening a game at all, when i move mouse cursor across the desktop it lags out big time. Once I close origin down all of the sudden the cursor lag goes bye bye, further more just so people know about it and perhaps educate themselves on it, in an attempt at stopping piracy of this game EA has implemented a new DRM called Denuvo which is more or less an anti-tampering system set to slow down people from cracking/pirating the game to play for free. This new DRM has been used in lords of the fallen and fifa 15 and seems to be hindering these titles from their full performance, I understand EA wanting to stop people from getting the games for free, but with that being said the anti tampering measures waste space on my hard disk and waste valuable resources that are needed in order to get the maximum performance from the games themselves. I would say that they reallllly need to look at this better and go back to the drawing board and get a patch out ASAP, I would imagine if they fix the issues with origin and the drm most of the sluggish performance issues will be resolved.
