I purchased it this morning, and it's great.
Works very nice on pc, with actually functional mouse and keyboard controls.
And no crashes yet. And I can actually run this on win10 with no trouble.
And I run it at 3440x1440 @ 60fps.
With regards to dsfix, that was never a perfect fix for me. It worked sort of ok, on some OSes, but I was never able to get it to work on Win10, or on monitors that run at different frequencies than 60Hz.
So, it's definitely way better than with dsfix in my experience.
The only shitty thing is, you have to pay 20 euros (half price if you already own the original) for something that should have been delivered on release day.
