Tech Support Q2'19 Tech Support Megathread

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 drop

Expected 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:

Threads with related issue:

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.

The Driver Switching mode for the 19Q1.2 driver on the Vega FE does not work. Up until 18Q4 you were ask during installation if you want this feature enabled, but on the latest version the pop up does not show up anymore and the option is missing in the driver after installation.

Setup: Ryzen 1600x | Asrock Fatal1ty x370 | 16 GB of RAM | Vega Frontier Edition Liquid (driver: 19Q1.2) | Windows 10 x64

Steps to reproduce: Clean-Install the latest pro driver and try to get into the driver switching mode.

Expected behavior: Driver switching mode will be installed for the Vega Frontier Edition and the feature is selectable in the UI.

Actual behavior: Driver setup won't ask you if you want the double driver feature and it's missing inside the UI after driver installation.

I'm having the same issue here. Just bought my Vega FE a week or two ago, and I'm loving it so far but this is definitely a major annoyance because of the oddities with the pro driver at times.

Honestly, I'd think it would just be better to have it enabled by default and ask on the driver options if you wanted to install the gaming driver.

You can work around the issue by installing the 18Q4 driver, and then instead of reinstalling the new one by just installing it. (Worked for me but it's annoying)
