Is all expansion +stuff packs and minimal amount of cc pushing it a bit too far for my laptop?

Ok hi guys! I keep coming here cause again I feel it's pointless making new posts for this.

I've got the game all good, capped fps(tested ingame with cheat, first it was going haywire but I fixed it after). It is mostly smooth with the occasional lag but the biggest annoyance to me, screen teraing. Vsync is on, so what else do I do to get rid of that annoying line whenever I move my camera. Thanks in advance!
