Yuri, could you attach +msvcp,+tid log running this game? I suspect it could be huge, but it's probably possible to reduce it to lines that contain numbers/strings that are affected by this formatting issue.
I cannot do that. After pressing Play button in uplay, log gets spammed with
trace:msvcp:_Towlower (109 0x47d4858) trace:msvcp:locale_id_operator_size_t (0x7e612110)
It could slow down an application, but it doesn't mean you can't use logging. Just wait longer.
