Cyncist, are you playing with version 18.1? with your 5700xt?

Hey there, yes I rolled back to 18.1 and am playing without issue.

I did an agressive underclock , the card ran at about 1400 mhz, the flashing was still there. Also the only way to stop it is to put the texture at low or lowest settings. the textures looks awfull at that setting! Other than that, I run the game with vsync 60 fps. I also tried locking the ddr5 speed and that didnt change anything. This is kinda sad because I ran the game fine with my 970, but the fps was low-ish. I bought this card to be able to enjoy a stable 60 fps ultra, but I am kinda wondering if these amd cards are worth all the troubles I had in my games.

Thanks for trying that and reporting back. This helps further confirm that it isn't at all related to heat nor instability from running near the clock/ram speed limits.

When you adjusted Texture to LOW or LOWEST, are you talking about TextureQuality or TextureFilter or TerrainQuality?


For the couple of users getting upset about my earlier post and suggestions of things to try: A few quick tests that hurt nothing DO help to rule out some of the potential reasons for these issues.
I've seen multiple reviewers mention the 5700 (particularly the xt) doesn't have much headroom and in rare cases (silicon lottery giving the finger) the card's own boost can be unstable for some games/workloads...basically meaning the GPU can act like you're running a slightly unstable OC even when you never OC'd. I'm not knocking the surrounding build-quality, but the quality-control of the binning/chip selection and default boost frequency isn't great. The snow effect is something I've seen from a reference 5700xt that was simply unstable with some games at its stock frequency..in that case the snow went away when the card was underclocked.
Because this thread's glitch had the same appearance and was affecting the same family of GPU's I figured it was a good thing to try to rule out.

The only workaround to this graphical issue for AMD 5xxx and 6xxx users is to roll back to version 18.1, or older.

The 6xxx-series AMD GPU's don't appear to be affected by this.

I am curious if their fix for the hd5000/6000series is somehow what's causing this version of this problem for the rx5700/xt.

For the textures, I was talking about the terrain quality option (low or lowest), I tested every other options there is and they dont eliminate the flashing of the terrain. I can also confirm that reducing the load on the gpu by reducing settings (except terrain) did not change anything regarding this issue. Also it is not possible to roll back to older drivers, because I am playing Red dead redemption 2 and you kinda need the updated drivers to have a good experience.

Thanks again for being so thorough.
That's really interesting since it looks like the LOWEST/LOW TerrainQuality settings are the newer options while the glitching MED-ULT TerrainQuality setting looks and performs like a18.1 did before the option was added.
I'm guessing their fix for the old hd5000/6000 GPU's "TriangleTerrainGlitch" that affected most of a18 until the most recent update might've borked the same surfaces for the much newer rx5700/xt cards....I also wonder if maybe the newly added TerrainQuality LOW/LOWEST setting gets around the old hd5000/6000 glitch.

Can you share a screenshot of how bad the texture looks at the TerrainQuality LOW setting as well as a similar shot of the same area at ULTIMATE? I don't think it's important, but I'm curious if the rx5700/xt cards are looking different at LOW compared to GPU's unaffected by this snowing/static glitch.

I took 2 screeshots for you Cyncist, low and ultra. https://imgur.com/6XEIUfK https://imgur.com/94RIKwP for some reason we can't see the small flashing textures, but I see them in game.

Description of the bug :

Upgraded from a Radeon RX 580 LE to the Radeon RX 5700 XT Red Devil & im getting little white flashing flakes on the ground, Not on main textures but were ever Textures meet, Gravel, Roads & Paths... Its hard to explain but its like the ground is flashing little specks...

Tested the following drivers all Fresh full install & system restart...

Adrenalin 2020 Edition 19.12.2 Recommended (WHQL)
Adrenalin 2020 Edition 19.12.1 Recommended (WHQL)
Adrenalin 2020 Edition 19.12.3 Optional

Recorded on my phone so ♥♥♥♥ quality but you atleast get to see what i mean...

Tested all 3 on a fresh install & there all the same, Only thing that made any difference in game was lowering Texture Filter to its lowest which nearly gets rid of them but still noticeable...

Just tested 18.3. Flickering bug STILL persists. Wonder how long we're going to have to wait for a fix.

[ColdNemesis]

Yeah I just tried it too, it still flickers

[ThotPocket]

Devs, it would be great if you could at least acknowledge you are aware of this issue.

[War3zuk]

I posted on the bug forum & know one has said out

[ThotPocket]

I know. There's been no reply from devs to this post either, and the most recent update hasn't fixed the game. I'm getting worried it will be a while.

[SammyR]

There was a mention from the devs that they believe this to be a Unity bug. I hope santa bought one of them a 5700 for xmas, then they'll at least be able to reproduce it.

[ThotPocket]

Still no acknowledgement or response from devs. So I guess everyone with a 5700 or 5700XT is just out of luck for the foreseeable future.

[SammyR]

At least they're calling it a known issue now. May the fixes be plenty and timely.
