D3D11 moiré effect

[OVH]

So I give UT v469 another try because I did not like it in earlier versions. I use it with D3D11 video driver and I notice some moiré effect in some maps that I dont have or less with D3D9 video driver in UT 436 and 469.

Example with the stairs of Soccer Stadium:

D3D9:

Any settings advice to remove or reduce this moiré effect?

Sorry, concerning graphics I'm out. Maybe ask on Github or Discord.
But I can show my settings and visuals:

Please can you share your D3D11 settings in [D3D11Drv.D3D11RenderDevice] from UnrealTournament.ini?

@OVH:
What's your card? Nvidia? Or Radeon?
I can check-compare (have different), since usually it might look different on different cards
Asking because I have same issue on NVIDIA too

On your screens d3d9 lines have some kind of Edge Anti-aliasing,

and on DX11 all lines are more jagged

Unless it's a driver or UT thing , this usually should improved by "Anti-aliasing" setting.
try this, to get rid of this effect "almost completely" (fast card might be needed tho):

Also for DX11 you can try "DXVK" wrapper (at least GeForce 700/Radeon HD7000 required), to improve performance on Windows Vista-7-8-10-11 (because AA might be expensive on some cards)
Just put the 32-bit DLL's into UT folder

You might also try the new "Vulkan" renderer. It's very fast , and doesn't load card at all.

Thanks. Aphex can you do the same please? Because in your screenshot some settings are missing.

I have same issue on NVIDIA too

try this

Yes its a Nvidia. In some maps antialiasing is making things worse. For example in BoomDockBridge the wall of containers outside is horrible and much better looking without AA.
So maybe there is something to change in the Nvidia control panel?

Also for DX11 you can try "DXVK" wrapper (at least GeForce 700/Radeon HD7000 required), to improve performance on Windows Vista-7-8-10-11 (because AA might be expensive on some cards)
Just put the 32-bit DLL's into UT folder

Its a wrapper for Linux using Wine. I dont see how it can be better than native Windows support?
Maybe a false positive for D3D11.dll but I dont like that:

Vulkan is fast but its using a lot of CPU. And also has the moiré effect.

I think there's no such setting specific for d3d, only "general" ones. But if your card supports some advanced AA like TAA (which may not have these issue), it can be only forced from that Control Panel

Its a wrapper for Linux using Wine. I dont see how it can be better than native Windows support?

It's not only for Linux. Last Win version of Half-life 2 from Steam has this DXVK pre-installed, and you can choose it in launch options.
Also one day I played a D3D game on Linux through Wine – it was faster than on Windows

Native Windows support seems only better in XP, which has more direct device access.
Vulcan, on the other hand, is more efficient API than DirectX 11 by design.

DX9 on UT works much faster (and better), but I think it's only question of time until they optimize DX11 renderer as well.

So, for older d3d (lower than 12, which ships by default in Win10) it's much faster to use DXVK even though it's Wrapper.
that's why I advised – it really improves performance. I also didn't believe until I tested – you can also test and decide

Maybe a false positive for D3D11.dll but I dont like that:

Yes false positive.

I also asked around, and it seems that this "more moire" is sign of "high precision" in rendering, which may explain why Vulkan also has this. Strange?

Vulkan is fast but its using a lot of CPU. And also has the moiré effect.

And what about OpenGL? There's lots of settings, and it's very fast, faster than Vulkan even.

[Aphex]

I think I found best solution:

Set render device to ICBINDx11Drv.ICBINDx11RenderDevice
And set "Resolution scale" to "3" for DX9 moire look (adjust as desired)
This way no AA is used, so shouldn't be any issues with the other map

Also you might want to adjust GammaOffset and other options as desired (in Preferences through Console) for DX9 look (highlighted in Green)

I think there's no such setting specific for d3d, only "general" ones.

There are 3D settings for each program:

I dont like it. Strange colors and lines.

More Resolution scale make things worse for me. I set gamma mode to XOpenGL because it look more natural for me DX9 is too bright.
And I set One X Lightmaps off because its making strange colors and light. Look at the ground the box and the strain at the back of the truck:

And Anti Aliasing num samples set to 2 is the best to reduce moiré. Also VSync is a must have or its laggy.

You tried "3.000000"? It looks exactly (pixel-by-pixel) as on D3D9 for me, basically solving what you inquired about.
I even switched renderers in-game (using "tryrenderdevice), and the jaggies you shown were on same exact places on ICBIND as on D3D9.

What kind of issues?

There are 3D settings for each program:

I mean there's no way to adjust per-renderer. So if you force AA it will be on all renderers.
You can try these settings:

Also VSync is a must have or its laggy.

You have lags without V-Sync?
Strange, because tt's not how it works. You get tearing when off – but when it's on it adds lags which you feel (screen doesn't react as instant to mouse).

Anyway, I think, these settings worked for me once, when I wanted to decrease lags by disabling Vsync. Try and feel instant response:

antilag-prefs-dx.jpg (108.72 KiB) Viewed 5642 times

Set "Min. desired framerate" to match your monitor's Hz.
Just don't set "Framerate Limit" in game, to match your monitor's – you will see "scanning beam" effect, since your monitor and game FPS use slightly different timings, and it's almost impossible to make perfect match.

In DirectX it only works properly when "DirectDraw" is enabled for both Fullscreen and Borderless. If you use other renderer, disable "DirectDraw" (Borderless or both).
StartupBorderless/StartupFullscreen also adjust to your preference.

If you still want VSync, I recommend you still make these changes (to adjust game for DirectX), maybe disable V-Sync (in renderer preferences), and then adjust V-Sync-related options (Force it from there) in Nvidia Control Panel, to reduce lag.
