2k16 vs 2k15 graphics and performance

[Big Chungus]

This game has seen some obvious graphical improvements with the introduction of body scans and the like, but the system requirements were/are the exact same as those for 2k15. I have a low end laptop sporting an unremarkable GT 840m, but I was plenty content with the settings I played 2k15 at and pre-ordered 2k16 (first ever pre-order of any kind in my entire life) assuming that I would be able to play at my 2k15 settings if not slightly better.

I can only maintain a constant 60 fps with the absolute bare minimum settings at 720p including the crowd turned completely off (save for texture quality, which seems to have zero performance impact for me). The issues with this port thus far are well documented, so I'll try not to drone on and complain here. What I'm wondering is:

What is a rough timeline for which we can reasonably expect updates/improvements from either VC and/or NVIDIA (both on the performance end, and on PC-specific bug fixing e.g. bugged rebranding, player icons, etc)? This is the first game I've owned at launch, so I'm new to this. Ever time I watch gameplay from an Xbox or hear about how much a PS4 player loves this game, it makes it that much harder to be patient.

Is it a reasonable expectation that I will ever be able to run 2k16 at similar settings to what I ran 2k15 at? I was content with my 2k15 settings, but it feels like a shame to play at anything too much lower, let alone my current state of bare minimum that I find wholly unacceptable for gaming. If I'm never going to be able to run at anything much higher than the minimum, it might be time to seriously consider saving up for better hardware or just flat out trying to put this game out of my mind and coming to terms with my wasted purchase money. On the other hand, I can be patient if I have a good reason to be :)

Thanks in advance for any insight fellas :D
