OS is 64-bit. I loaded the runtime. It works now, but is the same khash as the x86.
the more cores your computer has, the more significant the performance boost, you should also use the EXE from the intel folder, the VS one is inferior but included for completeness.
I'm confused now, I don't see a VS or an Intel folder. When I unzipped vcredist_x64 I'm getting a bunch of numbered folders 1028, 1031, etc. I ran Setup and when I rerun it it just wants to repair Microsoft Visual C++ x64 Redistributable to it's original state each time.
I've also just noticed that it's getting incoming blocks like 3 or 4 at a time. It could be they're coming in close together, but I think I'm getting them like simultaneously.
EDIT: Okay, I see it now.
