Flickering edges and super jagged high-contrast lines despite MSAA 8x/8x

Hi everyone,

ever since I built my new PC (Ryzen 9 7950x3D, MSI RTX 4090 Gaming X Slim, 64GB G.Skill Trident Neo Z, be quiet! AIO, ASRock X670E Pro RS Mobo [Bios 2.02]) I have major graphical issues in WoW. Thin lines that contrast with the surrounding pixels flicker a lot. this is particularly visible in Oribos on the stairs, oldish continents like Pandaria and foliage + trees. I’ve made a video about it but unfortunately can’t link it since I’m a new user in this forum.

I’ve had an 8700k with an RTX 2080 before and never had these issues. I tried using different Dsiplayport cables (since I first thought it was a monitor issue), tried different power outlets, tried different drivers, refreshed windows and looked for a solution everywhere. My monitor is an Alienware 3418DW and I tried switching GSync on an off, treid different settings in the NVidia panel, tried different AA settings in WoW.

If anybody has any ideas what I could try I’d be super grateful!

Make sure you have Multisample Alpha-Test enabled.
Also 8x MSAA isn’t really needed if you are playing in 1440P or 4K. 4x is fine for me.

Thank you for your reply, I already have Multisample Alpha-Test enabled. I switched to FXAA High + MSAA 8x/8x which seems to make it a bit better but it’s still very strange and I didn’t have these problems with my 2080.

P.S.: I’m the OP, I just switched profile pics :D.

You can use the </> option on the link, like this, then it will work.

Awesome, thank you for the advice. Here’s the two videos I made:

You are talking about the flickering right?
There is some flickering in the game, especially on shaders that you can’t get rid of fully, even with downsampling.
That being said, have you tried to increase the resolution scaling a bit?
The 4090 should handle it to maybe 150% easily (also you might want to lower or turn of RT shadows if you have them on).
My best advice is to turn on some OSD like MSI Afterburner and monitor the GPU load while you adjust the resolution scale and settings to get the best image quality while maintaining high FPS.

Yes, exactly. The flickering is crazy and in real life much worse than the video makes it seem. It does not seem to be AA artifacts but rather some weird driver issue. I have these artifacts in Youtube videos as well once a thin light line is slightly diagonal. It looks like some weird image sharpening effect that makes roundish shapes look pixelated.

I contacted NVIDIA and maybe the manufacturer (MSI) next. It looks like some DPI scaling issue.

Are you using any scaling in Windows?

Ok then it’s definately not the game.
Maybe some Win 11 thing if you are using that… i’m still on 10, no rush to upgrade since everything runs fine :slight_smile:

Have you checked in your monitor’s options if there is something that could cause these artifacts? Maybe the response time is set to the fastest (this causes artifacts on my LG).

Windows scaling is set to 100%.

I’m not using the standard response time I always used since 2018 with my old 2080. It seems to be a general issue with Windows and/or the nvidia Drivers. I tried installing older ones but nothing changed. I reinstalled Windows, nothing changed. it’s as if there was some weird interlace filter on some parts of the screen.

Well if it’s not a driver or windows thing, what could it be…?
I didn’t have this with my old 2070S and i don’t have it with my new 4090, on Win10, driver version doesn’t matter.

I don’t know. I opened a ticket with the NVIDIA customer service and hope we will find out. Maybe the VRAM is broken on this one. It’s really hard to say.
