I've seen this a few times in the past, but it's now close to 50%. The error comes up at start of a match, after the 3d stuff renders but before the player list overlay is drawn. It might be map specific, but I haven't done enough testing to be sure.
I'm running an i5-2500, nvidia 450, 8 gigs of ram, Win8 (not 8.1, but otherwise up-to-date). Game is running as admin.
Is this a known issue? If not, how can I help debug? Are their any client-side crash logs I should send?
EDIT:

EDIT2: It is not map or mech specific.
