Hi, I have problem with maps modern app in windows 8.1. It freezees at start then show BSOD , when I close app before BSOD my VGA Radeon HD7850(WDDM 1.3) Catalyst popup say that drivers were restarted. On other PC's with HD5770(WDDM 1.2) and HD4570(WDDM 1.1) everything is fine. Is it problem with WDDM 1.3? I tried all drivers realeased on windows 8.1 from stock to last 13.10 beta.
