I see, thank you very much for providing alternative solutions, I will probably invest in a cooling pad.
TF2 under using the i7 threads answers my initial concern.

I've experimented with different games without encountering this problem.
Xcom 2 in medium/high settings runs without any problems, CPU was running around 75-90% usage with a stable 70-5°C.

I rolled backed to an old config I used to run and things seems to be doing alright so I'll stick with it.

Sorry for the late reply and thanks again.

I tried low-medium-high quality and I get about the same performance for all the different configs.

Alimentation is already set to high performance.

What I find weird is that my CPU usage sits at 42% in game and the GPU is around 30%

Thanks will do.

My laptop (gt73vr 7rf) is clean and I have no temperature problem CPU runs at 32-40°C when idle and 55-65°C when playing TF2

I am running on windows family edition, I will try these option out.

Here is my custom.cfg just in case:

Thanks!

launch option:
-novid -nojoy -nosteamcontroller -noff -softparticlesdefaultoff -reuse

I installed the .vpk in the custom folder and I reinstalled my game to clear out all my previous cfgs.

Then I did a custom.cfg file to tweak some game settings and class binds with the _c.cfg format.

Hey so I've been fiddling with different configs but I can't find the right balance for my rig, I would appreciate if someone could hint me toward an adapted config for my setup.

I'm playing on an MSI laptop and here are the specs:

CPU:
Intel Core i7 7700HQ @ 2.80GHz overclocked at 3.48Ghz
Kaby Lake 14nm Technology

GPU:
GeForce GTX 1080
Memory 4095 MB

RAM:
16.0GB @ 1195MHz (17-17-17-39)

Motherboard:
Micro-Star International Co. Ltd. MS-17A1 (U3E1)

Monitor:
Gsync
1920x1080 pixels
Monitor Frequency 120 Hz

Storage:
931GB Hitachi HGST HTS721010A9E630 (SATA)
238GB Intel Raid 0 Volume (RAID)

The game is currently installed on my SSD, I have tried Comfig: midquality and compquality, B4nny and an old comanglia cfg.

The cpu could be the culprit of the limited performance, however I found that it rarely process over 50% no ore does the GPU.

I'm currently using the midquality comfig and the game runs at an average of 80-100-150fps the highest value is in the spawn room with around 180-220fps and the lowest is during intense teamfight where it can go down to 68fps.

I also tried capping the fps to 121 the game was more stable with less noticeable lag spike but not as smooth as without the cap.

edit: adjusted fps value after new evaluation.
