Interesting. Seems to be that way on I7 8700K aswell, doing core 0-2-4-6-8-10,
and afaik my real cores are 0-1-2-3-4-5.

Using these two patches:
https://github.com/ValveSoftware/wine/commit/ec795b741d316ae18ab68dc0b75b2df91855fd04
https://github.com/ValveSoftware/wine/commit/5381caf1be5fb176f623ca96b3cd72f7a1154f9e

And setting "WINE_LOGICAL_CPUS_AS_CORES=1" makes this BoostTester run through
all cores+threads, so guess it is some sort of detection thing from wine.
Maybe the real/threads layout is different for various package types, and wine
would need some sort of mechanic to get this from kernel (possibly not easily
obtainable from userspace), or one would need a cpu-id thing for
"most-popular-cpus" with a fallback to what it is now?

Not a solution to the issue, but atleast something to experiment with if you
want to.
