Ok guys, first of all thank you for your replies. So nice to see that the community wants this game to be successful just like me. I have an update:
I noticed that Battlefield 1 is also stuttering quite a bit (not half as bad as Payback though), this leads me to be believe that, while Payback may be poorly optimized by itself, the Frostbite Engine as a whole may be having issues with the Windows 10 Fall Creators Update as well.
Also, I turned off game mode (I am running the game on W10 Fall Anniversary Update) and Turbo mode (or something like that) on my BIOS and the game seemed to have improved quite a bit. Too bad I didn't have much trial time left (and I'm definitely not buying the full game on this state), so I couldn't see how the game performs in the long run, but you should try this anyway. Online was still bad though. I've also seen someone comment that turning off Storage Sense in the storage settings also helps but I didn't test it.
And EA (or Ghost), as you can clearly see by the replies, I don't think this is a hard drive issue, neither one special to my computer. We shouldn't be looking for workarounds just to play a finished 60 dollars game properly. The problem is in the game and/or in the Frostbite Engine as a whole. please look into it.
Finally, completely off-topic, but can we sell cars in this game? I didn't find any option to do so LOL
