play dota 2, and im having a driver error with my radeon r7 200 series with the latest update on 5/17/2017. Dota will not boot up from steam it just reads: "unable to find a valid direct 3D device! Check the your graphics driver is working properly. I have played dota in the past with no problems it seems this last update has made it unplayable. When i disable the driver it launches dota but obviously it cannot perform. When I re enable the driver, dota will not boot i just get the same error message please help!
