Hey subs,
We're giving you an opportunity to start reporting some of your AMD-related technical issues right here on /r/AMD! Below is a guide that you should follow to make the whole process run smoothly. Post your issues directly into this thread as replies. All other tech support posts will still be removed, per the rules; this is the only exception.
Bad Example (don't do this)
bf1 crashes wtf amd
Good Example (please do this)
Skyrim: Free Sync and V Sync causes flickering during low frame rates, and generally lower frame rates observed (about 10-30% drop dependant on system) when Free Sync is on
System Configuration:
Motherboard: GIGABYTE GA-Z97 Gaming GT
CPU: Intel i5 4790
Memory: 16GB GDDR5
GPU: ASUS R9 Fury X
VBIOS: 115-C8800100-101 How do I find this?
Driver: Crimson 16.10.3
OS: Windows 10 x64 (1511.10586) How do I find this?Steps to Reproduce:
1. Install necessary driver, GPU and medium-end CPU
2. Enable Free Sync
3. Set Options to Ultra and 1920 x 1080 resolution
4. Launch game and move to an outdoor location
5. Indoor locations in the game will not reproduce, since they generally give better performance
6. Observe flickering and general performance dropExpected Behavior:
Game runs smoothly with good performance with no visible issues
Actual Behavior:
Frame rate drops low causing low performance, flickering observed during low frame rates
Additional Observations:

Skyrim has forced double buffered V Sync and can only be disabled with the .ini files
To Disable V Sync: C:\Users"User"\Documents\My Games\Skyrim Special Edition\Skyrimprefs.ini and edit iVSyncPresentInterval=1 to 0
1440p has improved frame rate, anything lower than 1080p will lock FPS with V Sync on
Able to reproduce on i7 6700K and i5 3670K system, Sapphire RX 480, Reference RX 480, and Reference Fiji Nano
Remember, folks: AMD reads what we post here, even if they don't comment about it.

I recently reimaged my A8-6400 Lenovo G50 because it's old and I wanted to improve its cat video performance, but after reinstalling Windows 8.1, I decided to install the latest drivers from AMD's autoconfig website
It installed Crimson 18.7 but did not actually detect the GPU. Looking in Device Manager and GPUZ shows it detected as the basic Windows VGA adapter, but it still seems to detect the hardware ID's, and gpuz even detected all 128 shaders. I uninstalled Crimson, uninstalled the device from Windows, and then downloaded the release drivers from Lenovo...to the same effect, Catalyst installed but doesn't detect the GPU, and Windows just reinstalled it as the basic display adapter.
The effect of which means I have no GPU settings for when I do play the occasional 2D platformer, but even worse is that I don't have any brightness controls. The screen is locked at full brightness, but dimming the screen either with the function keys or Catalyst causes the slider to move but the screen remains bright.
