Personally, i would recommend TAA but set your renderscaling to anything ABOVE 100, not too much, 105 would be enough, this way you get SSAA (supersampling antaliasing) which looks much better imho. The higher you go, the more impact on performance but on newer gen gpus you might not see any impact on 105 or even 110.
You do not need anything in profile inspector, this is directly implemented in the sim.
