Hoping to ping @dadu042 with this - I've installed MW5:Mercs from gog.com - the gog galaxy launches, it launches MW5, and I get into the menu system, but can't get through even the menu choices for "Instant Action" before I get a crash. It looks like the current CrossTie (did you write it? thanks!) enables DVXK and VC++2015 x32/x64 properly.
I'm only trying so far with the built-in i915 video card, since that's a simpler config to troubleshoot before I start doing craziness like enabling bbswitch for high performance. Wondering if you could post a bit more of your config so I could see what I've got wrong.
Cheers!
