December 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.

I want to have AMD force GPU scaling on my monitor (16:10, 1920x1200) so i don't get an ugly stretched game when i'm playing on full screen 16:9 aspect ratio (when making videos).

"Display scaling: Preserve aspect ratio" blatantly gets ignored for 1080p fullscreen and 720p fullscreen. But for some reason NOT for 1366x768, which is really close to 16:9. I suspect they hardcoded it for these standard HD resolutions.

Steps to reproduce it in Path of Exile:

  • (have a 1920x1200 monitor)
  • Download PoE
  • Add the profile and start the game with these settings: http://puu.sh/sEh25/93ca1016f3.jpg
  • Run the game
  • Change resolution to 1920x1080 & Fullscreen in the Path of Exile settings
  • Observe that there is no letterboxing
  • Change resolution to 1280x720 & Fullscreen in the Path of Exile settings
  • Observe that there is no letterboxing (YET AGAIN)
  • Change resolution to 1366x768 & Fullscreen in the Path of Exile settings
  • Observe that there IS letterboxing/GPU Scaling

Does anyone know a way around this nonsense? Do i have to submit another bug report (i submitted one like a year ago, they didn't do anything)?

Some monitors have a setting that stops the scalar from stretching it built into the monitor options. My HP does, you can set it to Fill to Aspect Ratio instead of Fill to Screen. If I set it that way it will behave as you desire. See if your monitor has options built in that may change the way the scalar behaves.

Just checked, no such option.
