What is causing bottleneck on my ARMA 3?

[williamcll]

I'm stuck at 40-45 fps in game but task manager shows that my GPU isn't fully utilized, game settings are on high or ultra.

Model: gigabyte P34W v3
CPU: i7-4720HQ
GPU:GTX 970M
RAM: 16GB DDR3

SSD: crucial MX 500

Task Manager is not the best place to capture your usage.
In which game you experience that ?

try lowering textures

this might be your issue:

the 970 famously had 3.5GB of high speed VRAM and then 0.5GB very slow VRAM , marketed together as 4GB of VRAM

OP has a GTX 970M. Its core configuration also suggest that it's basically a GTX 960 with double the RAM. So it shouldn't have any issues with partitioning, and even then it would only cap off the last 0.5GB.

Providing an answer to the question proper, it's likely that ARMA 3's design makes it reliant on single core performance. Looking at https://www.techspot.com/review/712-arma-3-benchmarks/page5.html and seeing that it continues to positively respond to core speed improvements suggests so. Also looking at https://www.techspot.com/review/875-intel-core-i7-5960x-haswell-e/page8.html  with the FX-8350, 6350, and 4350, all three operate around roughly the same clock speed and they all have the same performance.

 

So basically, the software wasn't designed for multi-core CPUs (or it was, just not very well).

I have multi threading enabled

What I'm saying is the software is the problem and you can't fix it.
