Hey guys, so recently I bought Arma II to play Dayz, but I had bad fps and stutters at every setting even if i have good specs (i7 3770, 2 7950 in crossfire 8gb of ram...). I tried to fix this issue by changing some parameters and I thought the problem came from my Gpus, but everything was ok with them. Then I read that Dayz was a really cpu demanding game, so I realized maybe the problem came from my cpu.
So I ran a benchmark (heaven benchmark), opened windows task manager and saw that my cpu usage didn't go above 20 %. Also I couldn't reach 60 fps with the highest settings in the benchmark.
I checked with another game (crysis 3) and the cpu usage still didn't go above 20%.
Is this normal ?
I also experience stutter issues with some open-world games, even with the latest updates installed.

You'll need to monitor per-core usage and not global usage. You could bottleneck on a single thread yet have the others barely take any load.
Try HWInfo64 so that you can monitor CPU usage via MSI Afterburner's On-Screen Display.

If the CPU Usage History graph appears split, the computer either has multiple CPUs, a single dual-core CPU, or both.
To view advanced information about CPU utilization, at the bottom of the Performance tab, click Resource Monitor. Resource Monitor shows information similar to that shown in Task Manager, but with more details.
bit of a random suggestion but please try it.
Disable vsync if it is enabled. It uses a buffer which when it drops below 60fps it caps it low.
Might also be worth playing with the "-cpuCount=#" launch parameter.
Also a basic advice : update all your drivers specially the turbo booster for your cpu

the i7 3770 can process 8 threads and most games use 4 threads so if those 4 threads where at 100% that gives you 50% global usage on the cpu, so please check the working cores for CPU usage and not the global one and report back.
@tarek CPU turbo doesn't need a driver, its done using the CPU multiplier.

@DNA you are right i meant Intel® Turbo Boost Technology Monitor
