--- Comment #59 from Steve Ebey eaglecomputers.ok@gmail.com --- have that patch, and have stated that SSAO being turned off makes the flashing stop, but I still have textures that are not being drawn. I have tried the cache cleanup and other troubleshooting tips. I have no flashing with SSAO enabled under DX11.
