Ive got another new way to help you not only run call of duty ghosts better but you hole system you'll see a much more dramatic difference with AMD cpu's but it will still work on i cores.
1. First you wanna go and right click on the task bar and press start task manager and go on the performance tab
2. When you performance hit resource monitor and go across to the cpu tab in the top left
3. In the right you will see the perfomance of your cpu and all your cores now where it says CPU 0,1,2,3,4 ... You may or may not have some cores parked and will say parked in a faded grey
4. To undpark you cores you with need to on the start menu and type regedit and hot enter and go to edit and find new you will need to a code to access your cores
5. The is the code 0cc5b647-c1df-4637-891a-dec35c318583 and dont tick or untick any of the boxs and the go ahead and enter that
6. Now you can edit you cores and youll see these files on the right and there and the one your lookin for is vaultmax and at the end of it, it says 0x00000064 (100) now if you have the (100) then that core is parked
7. To unpark it you need to right click modify and change the 64 to 0. Once thats done you can go upto the top left and hit edit and find next and to the same again but only change the vaultmax if it has a (100) at the end and keep doing this entill it say your finished it'll vary to how many time youll ned to do it depending on the amout of cores you have
8. After unparking all the cores youll need to restart your pc and your cores will be unparked.
Hope you guys will like this and ive done it and wow i got about 15-20 more fps while playing most of my games so yeah enjoy see yah
