ParkControl - Does not need restart, shows options in Win7 Advanced power settings, instantly applied, good for comparisons. ie: Core1234 hit 100% then Core5678 will unpark and load will then be evened out.ĭisabling core parking evens the load across all CPU's regardless of the load percentage. Keeping it enabled will load your first cores more, and keep the last ones off, until HEAVILY used. MIN/AVG FPS will Rise, which is GREAT, MaxFps takes a very small hit, which means nothing as you never see your MAX fps as your average.īench Tombraider with Parked VS Unparked, while games may use 2-4 cores, if it doesnt "load" them that heavily, and you have 8 cores. Its great for notebooks/laptops to save battery, but meaningless and negatively affecting on desktops. I thought more people knew about this, Its one of the things you SHOULD do on desktops after windows installation. I have a program that does this, without restarts or registry edits. What is your opinion on this patch, will it make a difference to performance? Is it worth it at the cost of extra power for leaving the cores 'on' all the time? Windows 8 doesn't have the same methods of managing the CPU (it appears) and it doesn't have, in the same way as 7, parking (in its essence.) Under the cpu tab, in performance monitor, look at the core usage on the right, it will have the text 'parked' next to the N core and be grey'd out if you currently have any parked cores. You can see what cores are parked in Windows 7 by opening up task manager, under the performance tab by clicking performance monitor at the bottom of the window. Generalising wholesomely on both parts for the sake of TL:DR. After this, you have to assign PRBF2.exe to a. AMD however, according to the article, may have a small issue on parking as the cores are known to 'stutter' as they wait for their counterpart to switch back on, take CPU 0 waiting for 1 for example. Unpark your CPU Cores in ProcessLasso->Options->Configure CPU Core Parking->UNpark your cores. People are claiming significant FPS increases from this, take BF4 for example a 10-20 FPS increase may be achieved using this registry patch (although I presume this is on older dual/quad cores or low end i3 config's with hyperthreading, where you want to squeeze all you can out of what you have.)Ĭertainly on the Intel side, with hyper threading, the process in which the cores interact are on an individual basis, thus not having an issue with other cores being in a low power, dormant state. It should then, presumably when called, jump into action anyway, not causing an issue. I mean, with modern technology and how Windows 7 manages resources, I would assume that the N core is parked for a reason, as its not in use, save a little power here and there. But with parking, I am skeptical of a possible performance gain by applying the 'fix', especially on i7 systems. Now, I know there is a known issue, in which you can try to pry a Windows 7 multi-core patch from Microsoft as Logan did. See SkilledRebuilds post \/ DOWN \/ the page, but this application is better: It modifies the registry to disable core parking in Windows 7/8. So, I came across this nifty little application (thanks to a YouTube gamer, rivaLxfactor)
