And i test it without success. Always bad performance with all my cpus enabled.
Okay, thanks for all your testing. It again suggests that this is not a Wine bug after all and something else (probably the kernel) is to blame. We should probably try to figure out what's the peculiarity of Far Cry 3's CPU usage that makes it so troublesome for Ryzen. If someone has any other idea how Wine could be implicated in the bug, that would be interesting too.
BTW, we certainly want to fix GetLogicalProcessorInformation[Ex]() anyway.
