Sometimes I play with shadows on far, LOD at 100% (it usually makes no diff, just was messing with it when I took the pic), bloom sun shafts and some AA but usually this is my setup. 50-60 FPS outdoors with 40's in the low end, 60 - 80 in doors (pois, bases, etc.). View distance, reflections and particles make a large difference (shadows too, depending). A19.2 has had some optimizations that might/should help a lot, mostly. Don't forget to check drivers, and disable the bloat ware most systems come with (including Windows bloat).
