Have to load household twice to have over 15fps

@oaana Sorry for the late reply; I've been a bit busy with other stuff.
Before getting into the hwinfo log itself, there are a couple things to note. One is that a component of Razer Synapse is crashing. Please try playing without Synapse running; you can end it in the Task Manager before launching Sims 4. You're also running low on storage on your C drive. While it might not account for the Sims 4 issues, could, and it should be addressed regardless. Having at least 20 GB free is a good goal and should eliminate free storage as a possible contributing factor.
Finally, it looks like your monitor is plugged into the motherboard on your computer. Please instead plug it into the graphics card. In case you need a diagram, I often borrow this one from someone else (he doesn't mind):
For the hwinfo log itself, there is one concerning reading, and that's the voltage on your power supply. From the age of the other hardware in your computer, I'm guessing the PSU is about four years old, which isn't too old by itself. But its voltage drops might be enough to cause problems soon, if not now. If you do start to see issues, especially restarts, the PSU would be the first suspect.
I also see a lot of fluctuation of the GPU's core load and video clock, although they don't seem to correspond to the voltage drops from the PSU, so they're not necessarily related. Both drop way down when you go into Map View or (usually) load Built/Buy, which isn't surprising. What's more surprising is how inconsistent they are when you're not loading anything, often but not exclusively when you get low fps. I'm not saying there's anything wrong with your graphics card, more that I see how you could get inconsistent fps for no apparent reason.
It's entirely possible that this is due to your plugging the monitor into the motherboard. When you do that, the integrated chip gets used too, at least some of the time, and the system has to decide when to switch back and forth. If it's making the wrong decision at certain points and letting the integrated chip run the game, you'd see very low fps, maybe in the range of 10-15 like you've described. But it kind of sounds like you've found a way to force it to use the dedicated card again, i.e. going to Map View and loading the house a second time.
This is total speculation, especially because the dedicated card is still active when you get the fps drops. There aren't many stats on the integrated chip, so I can only guess what it's doing. But it would be interesting to know whether this problem is still present when the 970 is running things without interference.
And thanks for the very thorough report. Of course it was helpful information, but it was also fascinating to see what was going on in your computer while you played, and to match your timestamps with the graphs.
@puzzlezaddictHi. I have my second monitor plugged into my MB because it's a VGA port and I don't have this port on my GPU ^^. This being said, it's been years it's like this and I never had a single issue with it. But to be sure I removed my second monitor and only tried with one and... I still have this issue.
I also only have this issue with ECO pack... when I disable it on origins, the fps drop is gone. So I think it's in the game/ECO pack side. I've search my problem on google and I found so many people having the same issue.
Sometimes I have to reload the map, sometimes just clicking on the "..." remove the 15 fps and goes back to 60.
I've come up to the conclusion my only solution is to uninstall ECO until they fix it.
