Well after yesterday's news I was expecting the worst, but the game seems to be running well enough. No weird glitches, except maybe the water, and no crashes so far. Though I did notice it gobbles up RAM. Granted I am just playing at 1080p and with mostly the original settings, but I was expecting even that to be a shit show on this old rig. There was some awful pop-up, like the worst I have seen since the 360/Ps3 days, but it seems bumping up the model quality fixed it? Not sure might just be the placebo effect. I will see how it goes as I play it, but so far instead of expecting to just barely be able to play it seems I might actually have some wiggle room to bump it up from the original settings.
Granted I am much less sensitive to framerate then some so I am not saying the benchmarks were wrong just that so far the game is good enough for me.
