Shadow flickering in classic

Been playing season of discovery and having fun, but noticed some insane shadow flickering on terrain/objects in heavy populated zones like Ashenvale and Stormwind. Usually last a few seconds then goes away.

Do you have a 30 series card? Because I was talking to a bunch of people last night and it seems to be an issue with the 30 series card and wow. Started in tbc. It seems to happen alot in ashenvale/wsg when people are dieing.

I know dx 11 legacy fixes it but causes massive frame reduction so in big areas your frames will get tanked

Someone said turning shadows to low might fix it gonna see if that helps. But the game gets so bright with shadows on low lol

edit: shadows on low did not fix it

A few of us are noticing it happens everytime you get an honorable kill

2070 super actually.

interesting but most ppl dont report it so idk if itll ever get fixed unless a dev actually is told directly sadly

Edit: ok tried every setting in a bg its when you get an honorable kill everytime for about 4-5 seconds after the message pops up

Odd. I don’t do BG’s, prefer world pvp. But Ashenvale definitly has it during event.

yea its just easy to narrow it down in wsg because you are constantly getting honorable kills lol, but in ashenvale it always happened after a kill

As crazy as it sounds, i think its the honorable kill message that pops up causing it

Figured it might be sharding/layering

i have a clip of the issue unfortunately cant link it but i noticed it happening on graycens stream too in ashenvale when he got an honorable kill

Ahh I see, those are whole model blanks, but I can see where people would think they look like shadows or might be tied to the shadows. WoW had this issue during Shadowlands and it was mostly due to using MSAA. The usual solution was to just use image based AA(CMAA2 is pretty decent, especially if you play at 1440 or 4k) instead and to avoid MSAA.

I’ve seen this bug happening in quite a few other games lately as well. I wonder if there were some weird driver changes that are making some operations spit NaNs or something clamping/rounding related. Maybe something related to the culling/depth passes? Hard to say for sure.

You might also try clearing the Nvidia/AMD shader caches after making changes, just in case there’s a shader that’s broken.

literally happening to everyone when an honorable kill happens so i really think they just broke something

i personally am not using AA and most of the people i know dont

idk what card graycen has but i know everyone whos having the issue iv noticed is mainly 30 series cards, not the 20 series or 40s or even the 10s

Try DX11 and see if that works for now. There are a ton of moving cogs in the sea of variables between your game client and what you see on you screen, so figuring out where to point the finger isn’t always that simple.

Since you’re bringing up that it’s mostly happening to 3000 series cards, maybe the common variable is something like poor quality ram from during the COVID shortage and maybe that’s causing certain memory related things to artifact. I mean that’s just one potential variable in the mix.

dx 11 legacy only thing that works but tanks the frames, and in any big area its bad

and the fact it doesnt happen on retail or other games and dx 11 legacy does fix it then its an issue they can fix

and it only happens in pvp/honorable kills too which is wierd

I noticed this in Ashenvale today after getting a honor kill.

I have the same issue after an honor kill in Ashenvale in SOD. I have a 4070 with all settings max MSAAx4 and RTX shadows high.

Hey all,

I am curious if there is something more widespread going on with this. Can we get some Dxdiags posted for anyone who is experiencing the flickering after getting an honorable kill in Classic? Also can we check if HDR is on and if this is happening only with Dx12? If HDR is on in Windows, does toggling it off help?

As for the Dxdiag, just copy the contents of the text file created and paste it here between two ~~~ like so:

DxDiag Here

If you have issues pasting here, use Pastebin and post the end of the link. (ie. 123456 for pastebin.com/123456)

It happens with dx12/dx11 and no hdr on. I can do the dxdiag in a bit. The only way to temporarily fix it is dx 11 legacy, but that cuts the frames by over 2/3 and causes issues for alot of us so its not really a viable fix, most people are just ignoring it when it happens.

Also from the 20ish people iv talked to from our guild its mainly an issue with people who have 30 series cards, 20 and 10 series not happening dont know about the 40 series. but apparently its happening on the 40 series too according to a poster above

Out of curosity ironthorne did you watch the clip i posted?

keep getting 500 errors trying to upload dxdiag and having an issue with that pastebin i think theres too much in my post to let me paste the dxdiag its like 10k characters long or something lol

Think i got it now for you Iron

Having the same issue, no HDR, RTX 40 series card, it just always happens when I get an Honorable Kill

Your report is showing that you have three listings for your 4070ti. Unless you physically have that many cards in your PC, you might want to go into your device manager and remove the hidden unused copies. This can happen from moving the GPU around physically between PCIE slots, or it can also happen when there’s a large Windows update like going from 22H2 to 23H2, or sometimes from BIOS updates.

  1. Right click start icon
  2. Device manager
  3. In the view options up top, click show hidden devices
  4. Expand display adapters
  5. Remove any duplicate greyed out copies of the GPU by right click->uninstalling them
  6. Reboot the PC

The duplicate copies of the card aren’t showing MPO as being enabled, which could bug stuff out for games that might think they have extra planes to write to, but don’t or vice versa. Depending on how WoW handles MPO, a lot of times, UI related elements are given their own plane independent of the 3D graphics, so that if there is any resolution scaling, the UI remains clear and unaffected. DX11.3 and 12 both use MPO, 11 legacy doesn’t.

So there might be some combination of bugs going on, but the duplicate copies of the GPU definitely seem fishy. Oh and make sure after you do the above, delete WoW’s config.wtf before launching the game. Not sure how WoW stores the IDs of GPUs and whatnot, but this should make sure that it doesn’t try to accidentally select one that’s been removed. Make sure to redo your settings as well, they will be at their defaults. This way, it will have to refresh the GPU list and then verify that there is only one 4070ti in the dropdown list.
