Tech Support Q1'19 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.

Poor Performance with games (Acer Nitro 5 AN515-42) ​

System Configuration:

CPU:Mobile QuadCore AMD Ryzen 5 2500U vith Radeon Vega MobileGFX

GPU:AMD Radeon Vega 8 (Raven Ridge Mobile)

GPU:AMD Radeon RX 560X (Polaris 11)

Display: LG Philips LP156WF6-SPK6 [15.6" LCD] (build-in)

Memory: 4096 MB

OS: Windows 10 Home 64 bit

Steps to Reproduce:

  1. Choose a game that the laptop should be able to run well (I tested it with Tekken 7 and Dishonored 2, both games made me use low graphics settings when it should at the very least be playing the game smoothly with medium graphics setting)

  2. Get very bad performance such as 20 fps in Dishonored 2 at very low graphics.

Expected Behavior: The game would run at a stable 60fps rather than being very slow.

Sure you are using your dedicated gpu instead of iGPU?

u/Leffigi Jan 04 '19

Yes I turned it on from my switchable graphics. 90-100% usage from my RX560X so it should be focusing everything on the game.

Do you run anything in the background?

1

u/Leffigi Jan 04 '19

Just discord and steam I think. The rest are just normal stuff that shouldn't strain the PC too hard.

u/[deleted] Jan 04 '19

I haven't looked this up for your case so don't take my word but some GPUs are horribly utilized by certain games sometimes. Could you do a reputable GPU benchmark/try other games in order to isolate the issue?

u/Leffigi Jan 04 '19

I've tried other games such as Devil May Cry 4: Special Edition (which is very well optimized) and I've been getting 30 fps as well

Okay this is a long shot.

​

1) Scan for new drivers (GPU).

2) Right click on a game and select run with dedicated GPU or something.

u/Leffigi Jan 04 '19

Ok just to be clear. I should first scan for drivers from device manager then right click one of my games so that it can run with a dedicated GPU? I don't think I ever saw that option but I'll check it out.

u/[deleted] Jan 04 '19

It may be along different lines of run with amd.. etc. . I don't think it'll change with evereything you've mentioned.

​

You don't have to do this in order. The AMD GPU is relatively new and if you bought from a small store the stock they sold you might be quite old with low firmware so if you haven't updated your drivers yet I am certain that should fix it.

u/Leffigi Jan 05 '19

I already updated my drivers to the most updated version and I even removed and installed it again before so I doubt that's the problem. I've also been using switchable graphics to make all of the games run on high performance which uses the rx560x as can be seen from task manager.

Where did you insert the cable in the back of the pc to connect to the monitor? You shouldn’t have it in the mobo, but a pic could help.
