Is 4gb vram enough to run read dead redemtion 2?

I played rdr2 on a 1060 3gb before I upgraded my card. I had to turn pretty much everything down to low except for texture quality, keep that high or at least medium cuz anything lower and it straight up becomes a ps2 game. Was able to get around 50 fps most of the time, up to 60 indoors and 30-40 in saint denis. Your 4gb card should get better performance than that due to higher vram tho.
