I used 16.3 drivers; decided to roll back to 15.11 beta drivers and saw marked improvement in CF for the games that needed it the most. For both sets of drivers I had CF enabled and I checked the CF profile setting and I enabled the CF logo to display in-game.
Here's what I'm seeing across all my rigs with Crimson Drivers
Here's what I'm seeing between the two drivers performance wise:
Bioshock Infinite, Thief, Tomb Raider 2013, Hitman Absolution, and Shadow of Mordor I'm using guru3d settings for the benchmarks.
Shogun 2 is completely maxed out on settings
Rome 2 is Extreme/Unlimited Memory
Attila is Extreme/Unlimited Memory
Crysis 3 is completely maxed out (5 minute Jungle level run with Fraps)
Dying Light gameworks off, rest of the settings maxed out (5 minute run with Fraps)
Grand Theft Auto V MSAA 2x, 5/4 Frame Scaling, rest of settings and extended sliders maxed out; average of 5 internal benchmarks
15.11 Beta and saw some instant boosts to ATW and Rome 2 in CF; from 20 to 38FPS (in August I was getting 40FPS with my 290X CF with the same rig/settings) and from 46 to 75FPS respectively.. The games that needed the most help from CF are the ones that got better from the older driver; Rome 2, ATW, Dying Light. Dying Light I went from 55FPS with flickering/screen tearing to smooth 91FPS; Shadow of Mordor benchmark went from 111FPS to 146FPS , Shogun 2 went from 66FPS to 74FPS. The only game where I noticed a big pro from the latest Crimson drivers was in GTA V which went from 54FPS with Crimson down to 45FPS with Catalyst 15.11 Beta, Hitman Absolution, Tomb Raider 2013, Thief, Crysis 3, and Bioshock Infinite were all very close between both drivers, so not really a change there.
Not sure why the extra links inserted themselves for my Crimson vs 15.11 benchmarks, click on the Crimson 16. Vs 15.11 Part 1 and Part 2 Photo links, those are the correct ones for my comparison of Crimson vs 15.11.
