sims3/sims4 keep stuttering when panning across

I've tested TS4 in W10 only, but a friend with almost a same pc but using W8.1 did the same test and we had the same results (fps drops even playing w/o mods and in the lowest setting possible).. Unticking Uncompressed textures seems make the things a little better but not too much (and the game has fps drops even if the sims are in another storie of the house, just moving the camera from side to side or panning creates the drops).

As I only have installed W10 in my pc I can't test with 8.1 now, but when I had 8.1 I had the same problems (fps drops but not too brutal as now). 
With TS3 I had the same issue even on differnt pc's (and I've tested on W7/W8/W8.1 and the same happend no mattering the hardware of the pc, ex: PC1 (Phenom x4 2.4ghz, 4Gb of RAM, GTX 460) and PC2 (I7 3770, 16gb of RAM and GTX 770) had the same fps drops.

Note: I've installed Nvidia Drivers 347.52 and it seems that those drivers are working a litlle better but not so much, part of the problem can be caused by the drivers but the other part is caused by the game. I don't have this kind of issues on any of the others games I play or I've played, except TS3 (I hated TS3 because of its crappy performance but kept playing because the game was "good" in terms of the things you could do)
