I must talk about PC state of this game.

@NB_Blessed For now it's on high. But like I said, tweaking graphics does not help, I tried many variations. All struggle to run the game properly. It's ridiculous. Even with low setting there are moments where the game just lags on low res.

I have a similar setup to you I5 8600k @4.7ghz, 1070ti running at 1080 speeds. 1900x1200 res. All maxed out with  vsnyc, locked 60fps no dips. Only had 1 crash in about 3 solid days play.

My game constantly crashes and most times ends up shutting my laptop off. Tends to only crash when there's a loading screen. 

Your problem might be your cpu.

The 4770 without the k is only 26 percent better then the absolute bare minimum requirement this game have.

I myself have a ryzen r7 1800x where it runs without any trouble at all, and that specific cpu is 51 percent better then your 4770.

The strange thing is however that you run it at 1366x768 which might indicate you run on a laptop, but i never have heard that a laptop have liquid cooling and your psu suggests you just running a desktop pc.

Still, your cpu is really not powerfull enough to keep up with your 1070ti. And on top of that, im suspecting your ram is still ddr3, so all with all you dont have a balanced pc at all.

So all with all the biggy here might be your cpu which is bottlenecking your gpu, which might clarify that you have bad performance.

However...

You might wanna try look if its possible to switch the direct x version of the game.

Cause, lately, dx12 games (and especially frostbite games) seems to like to crash often.

In fifa20 it was possible to switch the direct x version via an ini tweak in my documents, so i don;t know if its possible for heat too, but you might wanna go look there, to see if its possible nevertheless..

And then, while in dx11 mode, it still runs like garbage, then you might seriously wanna consider getting your pc more balanced..

And yes, i know it costs money.. But seriously, sometimes people think that a pc for modern games can come away with either a good cpu or a good gpu, and then having a mediocre counterpart, so good gpu, bad cpu, or good cpu and bad gpu.

But truth to be told, you need both at such a level that they wont go bottlenecking each other.. Cause if one bottlenecks the other, you run into problems..

I know this might not be the answer you were hoping for, but according to my knowledge (i build pc's myself and sometimes for others too) this situation is likely the case here.

But like i said before, first try search if its possible to switch the direct x version for the game via an ini tweak or something like that.

@Tormanbin It's definitively is a lazy port. I got no struggles running any other game on Frostbite. Or any other game for this matter on my rig. NFS 2015 runs smooth as butter, as well as Payback. So this is no excuse with a year window of release.

@maramsp1985 You could be right nonetheless my rig runs any game just fine. Hell, any other Frostbite games ran fine. Battlefield V as well as NFS 2015 and Payback ran great even upscaled. Other similar games I got no issues neither, this game however is only one that is recent enough that gives me such a hard time to run. It seems to me just a lazy port, honestly.
