I use since a few months a freeware named "game booster". When it was 2.0, it was already better to run the game, but now with 3.0, I see definitly more the difference when I am in ultra setting with more than 15 000 men on the battlefield.
Game booster boosts your system in order to have more CPU and launches each time your launch a game. It can work for whatever game you play but I find it particulary adapted to TW games. So it can help the players that have a low performance or those like me who wants always more soldiers.
here it is, it's totally free and I never had any problem with that. Hope it helps,
