Many AMD drivers, Nvidia too, have regressions for a specific games.;-)
it has happened with Gears of war, with Forza Horizon etc.
Report the issue.
Outer Worlds works very bad compared with Gears 5
In my setup, Ryzen 2600, dx11 wins for a ≈ 10%.
Maybe in old cpus that sandy Bridge, AMD FX etc dx12 works better
Grid runs more faster in dx11.
7970 core 1150mhz / 1500 mem
Best driver ever for Fire Strike.
At level of ps4 or more, 7970 works very well with Destiny 2, Forza 7, resident evil 7, Injustice, Tekken 7, The Evil With in 2 etc.
With this driver have looooong loading times in FORZA 7. Five minutes or more for start a race.
Fall creartors update and 280x/7970.
With Forza 7 support?
Only Polaris it's supported
3.Compatible with: AMD Radeon™ RX 400 & 500 series GPUs. Supports: DirextX® 9, 11, 12 & Windows® 7/10.
API Overhead test.
Creators update, back to Crimson 17.3.3 for stability:
Uvd bug GNC 1.0 it's fixed for me, can play youtube 1080p videos and after frequencies back to idle state 300/150mhz.
Play recorded videos...
Crimson Relive driver with old CCC (15.11.1) for color, brightness control etc
For me record works fine.
The same for me 20fps, but in win 7 works fine.
I think that WDDM 2.1 broke the game.
PHII@3.6ghz + AMD 7970/280x. Crimson 16.1, W7 64bits:
No idle bug for my 280X
Bingo, I've finished a resident process of a Metro APP and all back to normality.
Please try open different windows and chrome or firefox.
I detected high usage of VRam at idle 16.6.1 was 140MB, now with 16.7.2 mark 240MB anda if i open more windows memory increase too much....
DX12, mantle or Vulkan are used, mainly, for reduce bottleneck of the cpu if you have a beast processor the proft is minor or zero.
