I have Turok 2: Seeds of Evil installed on both my desktop (Lenovo ThinkCentre M58) and laptop (Lenovo ThinkPad T410). Both have dual core, not quad core, CPUs. With a bit of lowering graphics settings, which still look better than the N64 release, Turok 2 runs fine.

ThinkCentre M58 specs:
CPU = Core 2 Duo 3.33GHz E8600 (1333MHz FSB, 6MB L2 cache, 65W fan)
RAM = 6GB
Graphics = Nvidia GT 720 (900MHz) low-profile card
Operating System = Windows 7 Home Premium 64 bit

ThinkPad T410 specs:
CPU = i5 2.4 GHz (dual core)
RAM = 8GB
Graphics = Nvidia 3100M (256MB)
Operating System = Windows 7 Home Premium 64 bit

Yep, I don't know why quad is in the minimum requirements list. Like you said, it's possible.
I just bought the game and I'm playing it in a machine with dual core, so I can confirm you're telling nothing but the truth here. ^^
Unless the person is paranoid about having perfect performance constantly with high resolution and all effects at max, he/she should be just fine with a basic computer.
There's some minor lags in a some occasions, nothing that would make me wish to uninstall it, or make me buy an expensive upgrade just for this FPS.
Let's see the reasons why this N64 title became legendary (yea it's my first time playing this) !

I guess it's just because they haven't tested on dual core machines. Probably they don't even have one.

I now testet it on a Laptop with a Athlon Neo X2 with 1,6 Ghz paired with a Radeon 4300M and got around 20 fps Avg.
Didn't matter if Medium or low settings, so that was clearly CPU limited.
I would say we know the minimum rquirements now ^^

Cooooooool!. So, no problem with i5 7200u and geforce 930mx?. This game is a blast, will be a shame to miss it
