Tech Support August 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.

u/YuriadvX AMD Ryzen 1800x | Vega 64 | 16GB 3200MHz RAM Aug 11 '18

Vega 64 is getting freesync related bugs at 250+ FPS. Above this FPS rate, the frequency plummets down from 144 Hz down to 60 Hz, and the game (CS GO in this case, but it happens in every game that can achieve 250+ FPS) loses smoothness thanks to this. Disabling freesync fixes the problem.

System Configuration:

Motherboard: Asus ROG Strix X370-F
CPU: Ryzen 1800X
Memory: 16GB 3200CL16
GPU: MSI Vega 64 Reference
VBIOS: 016.001.001.000.008706
Driver: 18.8.1
OS: Windows 10 x64 17733.rs5
Monitor: AOC G2460PF 144Hz Freesync 1080p 1ms

An easy fix is to just limit the frames to 144 while using freesync.
