So, FPS dumps. Had them big time. Now I seems to have resolved it

Hopefully this might help some other folk.

Recently I have noticed that a lot of newer games give me terrible FPS dumps ( most notably EA games). I had this issue with Fifa 15 and today after I installed BF4 it was nigh on impossible to play they were that bad.

Apparently the problem is "Core Parking." All it really does is put your CPU or cores of the CPU in to sleep mode (known as C6).

Now, this only works for Windows 7 and for CPU's using more than 2 physical CPU's and/or more than 2 "Logical" cores.

It seems completely safe and nothing is deleted or irreversible in the registry.

- Go to Regedit

- Find this key:- " 0cc5b647-c1df-4637-891a-dec35c318583 "

- Within this key, there is a value called: " ValueMax "

- This value represents the % number of cores the system will park - the default 100% ie: all Cores are potentially park-able

- Change the value from 64 to 0 so the " ValueMin " and " ValueMax " are both zero

- You will have to find the key a few times and repeat the process for each time it is found - the number of instances will depend on the number of power profiles in your system [ in my DAW it was only found twice ]
- Do a full shutdown and power-off and cold-re-start

Since doing this FIFA 15 is almost like a different game. No more brain farts from A.I or Keeper, and the Jockey contain now actually works like I always thought it should.

In BF4 my horrendous FPS dumps from 50FPS to 20FPS and the freeze resulting from it are virtually 100% gone.

I remember reading about doing this when BF4 came out. I don't get fps dumps, but I'll try this anyway just in case future games might be affected.

For people with decent CPU's it might not make much difference. Although some have reported FPS increases with decent CPU's. Since nothing is deleted or irreversible though it is worth a try.

Just a caveat.
Those who didn't know Windows 8/8.1 don't have have this problem.

CPU core parking is disabled.
