[Jim Ablett]

thanks for testing Ingo. I will replace with old locks version.

Is the oldlock version you tested the last one I compiled here (I've recompiled it 3 times now) >

Jim.

YES, I checked and tested again! This version is fine on W764 AND XP64 and it is working as SSE as it is faster than the universal x64!

BYe
Ingo

Thanks again for the valuable info,

Jim.

Yes, no time losses, i'm running a minimatch 200 games chess960 2.2.1 sse42 vs 2.1.1, TC 10'' per game, sudden death.

Shortly the results (they won't be exciting).
