I just got a new GPU, a AMD R9 285, to replace my old HD 5770 and I'm encountering the weirdest glitch... shadows don't show consistently! Here's some screenshots: http://cloud-4.steamusercontent.com/ugc/37487890605970371/58B528BCB8702C2EDECA8376CE1EE913B74E34BF/ http://cloud-4.steamusercontent.com/ugc/37487890605970549/11C2BE6701566F8BF66A5C146110C7FD7AD448F2/ http://cloud-4.steamusercontent.com/ugc/37487890609176961/4844A32F0BC037ECED1BDBCC6D2BBD9397CFD088/ http://cloud-4.steamusercontent.com/ugc/37487890609177426/4B4ADB7269FE706097AD190FD22B69C3C510298D/ It also happens in F1 2013: http://cloud-4.steamusercontent.com/ugc/37487890609166273/70241DF6264D07B4A77A47DC77F990A5A4658D48/ Everything is set to max in the graphics settings, I ran a benchmark and I'm doing 59fps on average. While racing, shadow appears under the car, but it glitches when there are external objects that create shadows (like grandstands). I'm using Catalyst 14.12 driver (same one used with the HD 5770 card). Does anyone ever had that glitch? EDIT: There are no mods installed. Did a reinstall of the Catalyst driver + check local content in Steam, same problem.
