Solution for FPS lag spikes

[solarliving 10]

I gained an average of 11 fps without lag spikes (from 25fps avg in A3 altis benchmark to 36) by using an app called ParkControl see http://bitsum.com/about_cpu_core_parking.php

This software helped me, too. However, using parkcontrol causes a slightly higher cpu temperature in my case. Beware if your cpu allready gets dangerously hot!

my cpu: Phenom II X4 955

I made another workaround to "unpark" all cores months ago and have great performance too. It might be a good tipp to log cpu-frequency during gameplay.

You can also force the cores working on full speed also on lower usage levels very easily by using "Maximum Performance" power management mode in Windows. You can find the power management settings by typing eg. "power settings" in the Start menu search box. The "Maximum Performance" mode is the only right one to be used with PCs in practice anyway, the "Balanced" and "Power saving" modes are meant for laptops.

However, on some PCs the "Maximum Performance" mode might be hidden, but it can be made visible via some menu there (don't remember how exactly). In addition, some motherboards might force the CPU powersaving on (=decreasing the clocks of cores that have low usage) despite of the Windows settings, and in those cases the powersaving mode should be disabled also via BIOS.

Edit: whoops, I failed. It's true that even the Maximum Performance mode doesn't disable core parking, which is quite dumb... But it might still help by keeping the actually active cores working on full speed.

if more people say this works ill give this a go... but what exactly do I do? install and run and then run arma 3??

please look at first to your cpu-clock during gaming

Ha. I hope I wont be diverting the thread if I ask you this: Ive just taken a look at that cpu monitoring tool and I started wondering if there's any point in my overclocking the cpu if not a single thread is ever used beyond 80%?

3.4GHZ @80% not the same as 4.4GHZ @80%

No discernible change on an AMD Phenom II X4 970 @ 3.5ghz.

[Speederr 1]

No change for me :/

AMD 1090T 3.2ghz

[mamasan8 11]

No change, dualcore 3.2 Ghz AMD II X2.

I think your cpu is too old to have the parking feature. But maybe I am wrong.

All those CPUs have nothing to "park". Usually parked cores are threaded ones. For AMD FX users, there are 2 Windows optional updates (win7 and up) that they should install so that the OS can properly read the types of cores

What optional updates do you speak of?

N/M, found it myself....
