Low fps, and CPU/GPU usage

Every single playthrough of mine ends with around 300-400 rockets lunches per game, and I have to end there becasuse game has half of the orginal speed, witch is unplayable for me (arround 30UPS). And wierd thing for me as game developer CPU/GPU performance lock.

My specs:
CPU: Intel i7 4790K (overclocked 4.2GHZ)
RAM: 16GB
OS: Windows 7 64-bit
GPU: Asus STRIX 980TI
Motherboard: Asus VII Hero

I have turned on and off every single setting inside factorio for min-maxing performance, but except for Max Threads when set to 1 I lost 3 UPS, I saw no diffrence between 2-8.

Game version:
0.13.20

Map save:

Mods I'm using.

I know this is not a new thread because this was posted many many times before, and there is always a big discussion over topic (should devs take off limitation or not), but i feel like something might change if we will post enought threads of this topic :)
But my thought are, unleash power of my computer, since all modern games do this anyways, and dont worry about overheating and stuff of other players PC. Computers are made to be used 100% for 3-4 years. 24/7.

EDIT:
I hope those are not any mods that I'm using that slow down my game :(

try disabling hyper-threading so the game is using real cores, not virtual ones.

What? We don't limit the update rate. If you set game.speed = 10000 and your computer can handle it, it will run 10,000 updates/second.

The only limiting factor is your CPU speed, and RAM speed with a very tiny amount of GPU speed assuming you have the VRAM required.

Factorio is deterministic. Entity A updates before entity B before the rest so that's why you see it use 1 core to run the main simulation. To use a very cheesy saying: it doesn't matter how many women you have it still takes 9 months to make a baby.

Hey @Rseding91 Hows the multithreaded update massive overhaul coming along?

@OP, You can take a look at the F5 debug panel. The timings on the left are in ms.
If entity update is taking too long there's not much you can do. If it's something else then feel free to post it.
The debug panel will show mod timings too which might help you figure out if it's a specific mod.
