People are going to be very disappointed if they expect this to result in big frame rate jumps, suddenly making R7's match or outperform 7700k's in gaming.
..the scheduling fix will almost certainly result in better frame rates but more in line with a GPU driver update, maybe an extra 4-5fps rather than the jump in performance you'd get replacing your current GPU with a faster one.

So the SMT threads are incorrectly detected as full blown core threads?... Pretty much what everyone suspected.

it's like the Pentium aniversary, once patched it work really really great (for a 50 Euro CPU it work better than most I3 once OC)... but at launch: bug with OS and game.
1st buyer do the testing job 🙂 never buy the 1st.

Dat "threaad-schedulur" though... :P

Wonder if this still happens with the current Win10 RS2 insider builds? (15048 should have hit slow-ring yesterday, 1505x will probably hit the fast ring either later today or next week if it gets delayed.)

I just realized there was a mistake in my post, and it's too late to edit it again. A stress test in fact doesn't make full use of a core, that's why SMT in such an artificial benchmark will yield much better results.
I'm super tired, what was going through my brain as I was typing that, is that a stress test (some, not all) is one of the few things that can saturate a core properly for both threads. That's what I was thinking of when I said it can make full use of a core. In my half asleep state that somehow translated into the wrong statement. Sorry.

One would think AMD would be smart enough to work with Microsoft to have this sorted out in Windows 10 for the processor launch. Especially after their last processor architecture which needed Windows scheduling changes as well, and happened only after the launch. But apparently not.

If this is an issue in Windows 10, why does this affect only Ryzen?
Or is Intel also somehow affected by this?

I still wait to see does anyone plan to make a Windows 7 vs Windows 10 shootout on Ryzen or you are all just too scared from Microsoft.
And if you gonna give me the OLD OS reason go look at Steam statistics Windows 10 is loosing share for a second month in a roll and Windows 7 is gaining share on the Steam userbase.

Looking at the graph in the article linked below, IMHO we should expect the Ryzen's spike on the left of the chart to move right a bit and create a nice(r) Bell-curve.
