Yeah, when I visited Blaccy's farm (while he was still living there), I was getting a bit of graphical lag, despite having an x800 GTO graphics card, which you would think would be more than sufficient for something like this (despite being outdated by today's standards), and an Athlon 64 x2 4600+ CPU.
(I'm guessing you aren't using opengl or anything?)
Did you notice that something is rescaling the graphics? That takes time (and looks bad

). It's always the case here except in fullscreen, but if I found a way to make it more blindingly obvious: If I try to reduce my windows resolution to 800x600 while H&H is open and in windowed mode (NOT fullscreen), VPU Protect activates. If I then return to a higher resolution, H&H's window size changes to the same size as the desktop resolution (WTF?), but it isn't on top of everything else, and it looks like crap because of the scaling: It scales all the graphics up (or down) to the window size.
VPU protect was also triggering when I did :fs 0 after being in fullscreen, resulting in the H&H window being similar FUBAR and my having to close it and start it back up again.
