Hey

I have this problem since the beta
the gpu usage is not stable and pretty low on Crysis 3

I don't have this problem on other games

even without SLI i have the same issue

I tried to:

disable SLI
take 1 card out
disable \ enable V-Sync
limit fps with "Sys_maxfps"
set profile with NVIDIA inspector
Alt-tab
Unparked cores
Quit every process on the background
Low\Medium\High settings
Change power management to "high performance"
few diffrent driver
the latest driver
underclock my GPU because they Factory OC

My full rig:
Motherboard: GA-Z77X-UD5H
CPU: i5 3570k @ Stock Clock
GPU: SLI 2x GIGABYTE GTX 660 Windforce 2 OC
Memory: 8G Corsair vengence white low profile 1600Mhz
PSU: SeaSonic 850w Silver i think SD12D

look at the GPU usage.. (GPUx : TEMP, GPU USAGE, MEM USAGE, RPM on top left)

Crytek can't fix it cos they are too busy nerfing guns.

It's doesnt happen all the time, most of the time

i bet it's easy fix for crytek
