The bottom post, is directly copied from my AMD support forums post. located here https://community.amd.com/message/2691453#2691453 PC Specs HP H8-1455 Windows 10 I7-3770K 12GB DDR3 RAM ASUS 380X OC'ed Edition Corsair 550M PSU So I have been running on the the latest catalyst since I installed the GPU a few days ago.I decided to give crimson a go, since I read on a few pages that the new drivers boosts stability/FPS by quite a bit. Now I have a substantial drop in FPS, for example I used to get 60+ FPS with all applicable settings in their "high" positions in GTAV and ASUS GPU tweak II in gaming preset. I now can barley manage 52+ FPS and in some instances FPS drops from 52 to 42 FPS and sometimes while playing it can shutter very bad. Things I have tried to fix this problem. -Uninstall all related AMD drivers with AMD "clean up utility" and then reinstalled crimson 15.11.1. -Set all Global Graphics (available) settings to "use application settings" -Texture Filtering Quality to "Performance" -Disabled Frame Rate Target Control Global Overdrive -Power Limit = + 20% -GPU Clock = + 1.90% -(Base O'C settings is set with ASUS GPU TweakII "Gaming" Preset) Still no change in performance (FPS). Thanks.
