Problem description:

Ever since the Crimson update (9 months ago) every new driver brings more trouble than the previous. I particularly have problems with performance in GTA V with major stuttering and sudden FPS drops. Compared to Catalyst 15.11.1 beta, which seems to be the best driver for R9 380, with other drivers (16.3., 16.6.1, 16.7.3, 16.8.1), FPS drops up to 15 frames in average (see .xlsx table in attachment). I have only documented FPS benchmark data for GTA V, and haven't really tested other games. Crimson 16.8.1 seems to be the worst driver so far. I keep reverting to 15.11.1 because I have no other option. Main problem with 15.11.1 is inability to effectively utilize DirectX 12 in games such as ARK: Survival Evolved and Rise of the Tomb Rider. While Crimson 16.7.2 seems to be best for ROTTR since it boosts up to 5 FPS on average compared to 15.11.1 beta, it is still sluggish for GTA V since it produces much stuttering. In other games stuttering sometimes occurs and I get the impression that the performance is worse about 5%-10% compared to 15.11.1. My main goal is to achieve results of 15.11.1 with some new Crimson driver. Stuttering in GTA V is the main problem. I don't know why every Crimson driver seems to be worse than the 15.11.1. Is it because of some other drivers (chipset, etc.) or is it Crimson related problem? For the black screen issue, common for R9 380, I haven't really ever had it, since after testing I would always revert back to 15.11.1. Please advise if possible.
