That's the spirit!
Very , very short about my experience with AMD after long years again, after nvidia of course.
Nothing much. I have issue with vulkan due to changing over nvidia. I tested this card in other system and the vulkan works fine. Not here after changing from nvidia. i won't do fresh OS install. Don't have time for it. Some vulkan test runs , some not.
Only the additional settings are short as for many users.
I have been testing amd drivers over 3 months now(thanks for my friend).
With nvidia drivers(compare 3 months time) i had lot more issues after the driver install has been made(or not, because some of them, simply refuse to install).
Some other things has to be tested but so far the positive points are going on amd side. Only few to nvidia.
Anyway, i will make a video conclusion about my experience , you like it or not

Make sure clean Vulkan is selected. Should only take 10mins if everything goes well.
19.4.1 driver. rx 580. G4600 2c/4t
(GTA 5) when i was on 750ti cpu load was 100% and more frames per second
now cpu load below 75% and less frames
BUT some games like ac odyssey and witcher 3 works slightly better due more stable frametimes
now i'm waiting for more dx12 games
AMD's 'driver overhead' is not one single thing but an umbrella term. It's also not GCN specific but goes way back and across multiple different architectures.
In common use, it can be split into two separate areas being the actual driver overhead and a lack of Command List support.
If Game uses DX11.1 then Overhead is gone (look at BF1/5 or SWBF2)
Also devs need to code it that way
Also many new 'Engines' have it inside or 'in-house'
CryEngine, Unity, UE etc.
Which games use DX11.1 ? I barely found 2. Also, i can't really find informations about DX 11.4 and DX 11.5, but if we check in GPU-z it's showing as supported. So what's new with them ?
11.5 doesnt exist i guess?
Well maybe but gpuz is showing for all my gpus(even pre gcn) that dx11. 5 is supported
Where does it show?
GTS 450 shows 11.5 too.
but nv12 is 11.4 feature
11.5 doesn't exist and reserved for future in gpu z?
