After I installed window 7 and try to use realtime priority for taskmanager for my games, it just lag my game and freeze my game.
But when I had vista and use it, my game went smooth and stuff. But for window 7 it lag me and freezes it.
Is there any ways I can fix this?
7 Drivers are different from Vista's, so are a number of 7 API's and system processes. This is why you can have different behaviors in Vista and 7.
It is all up to you if you wish to change priorities, but I don't recommend you do this for the following reasons:
1. Realtime priority won't boost your game really
2. Software and game developers pre-set the rightt priority for their softwares
Several hours ago I tried the realtime priority for Call of Duty 4 MW 2 and for Mirror's Edge - it did work fine on my 7, felt the same speed as default priority. But it may not work the same way for all games and hardwares.
