If you are playing on DX12 then try to switch to DX11.
DX12 + FB2 are known to cause stuttering on some systems. Its seen in many FB2 games (Battlefield franchise, Battlefront franchise).
Also while your specs are within minimum the recommended BFV is a memory hog both on RAM and VRAM. 8GB ram is on the short side and tests have shown that BFV uses up to 11GB RAM when available. Also the 6GB VRAM on your GPU is on the lower scale and with both the RAM and VRAM being barely adequate it may add up to the stutter behavior.
The first thing you should try is to switch to the DX version you are not currently on. Also no need to the use memory cleaner for this game and in fact it may be a part of the problem, instead of a part of the solution. So dont have it running while gaming. Also check that that you havent turned of shader cache in nvidia 3d settings. If its off globally then turn it on, at least for BFV.
In any case you should consider upgrading to 16 GB RAM. Those 8 GB is going to hold you back for many AAA games and adding another 8GB of 3000mhz RAM is not very expensive. Many tests shows that the sweet spot for gaming is 16 GB and one of the games tested is Battefield V
