Sorry this is my first time reporting an issue on github, I'll go find it

Interesting... I've actually never played the game on Windows (or tried it with WineD3D for that matter), so never knew those effects were missing... it always looked good enough to me :sweat_smile:. I can probably get you a trace at some point if @Flypaste finds that too hard to do.

Edit: The said effects are not showing with WineD3D either apparently.

Ok so the template just... didn't appear when I made that first report. I clicked "submit an issue" and it just gave me a blank textbox. I found the template with a different submit an issue button.

I tried to get the apitrace, but it didn't work as expected. When I set the dll overrides in winecfg, nothing happened. So instead I set the dll overrides in the steam launch options with this command: WINEDLLOVERRIDES="d3d9=n,d3d11=n,dxgi=n" PROTON_USE_WINED3D=1
This generates the trace but the file is empty, and most importantly the game just crashes instantly saying it can't create the D3D device. So I had to disable D3D and go back to DXVK. Note that this crash does not happen when I remove the overrides and keep D3D.

Software information

Supreme commander forged alliance, but the issue is also present in the base game and in forged alliance forever.

System information

• GPU: RX 5700XT
• Driver: 22.0.2
• Wine version: 7.7
• DXVK version: v1.7-8-g51531e4a7

Apitrace file(s)

• Using DXVK I got the trace: https://mega.nz/file/hioFSDSR#3zFwiC7KOD0Nfg1F_bpUgA7YC6wZ1ukfcTBPMfJO5iw

Log files

• d3d9.log: Edit: Found it. ForgedAlliance_d3d9.log

Here's a trace captured with WineD3D, if that helps at all in this case: https://drive.google.com/file/d/1RJ7QglyjP0XB-PnQCmvE4IU5o-OzGr8v/view?usp=sharing

As I mentioned above, WineD3D doesn't fare any better and doesn't show the effects I've seen in @Flypaste's recording.

I tried setting d3d9.shaderModel = 2 & d3d9.shaderModel = 1 to see if that helps in any way, but it did not. The game refused to run at all with d3d9.shaderModel = 1, saying that it needs support for 2.0 at least.

One last thing to mention is that I'm on Nvidia and seeing the same thing, so the probability of it being something AMD-specific is highly unlikely. I'm also using the latest master build, not v1.7, but still getting the same.

I set the dll overrides in the steam launch options with this command: WINEDLLOVERRIDES="d3d9=n,d3d11=n,dxgi=n"

FYI, you only need WINEDLLOVERRIDES="d3d9=n,b" for the apitrace d3d9.dll to do its work. Setting it simply to "n" will get you the "failed to create Direct3D9 Device" message you mentioned.

@K0bin Here's what I'm seeing (and I think Flypaste is seeing as well). That being said, I'm not entirely sure what is causing the missing effects in both dxvk and WineD3D, since I have all the d3dx9 and d3dcompiler winetricks in my prefix...

Yup winter has shown it. This warping in swirl effect is the easiest way to troubleshoot the issue since you can see it immediately, but a LOT of shader-based effects are missing throughout the game. Someone who patched this on windows mentioned that the issue is happening because old directx shader models are being converted incorrectly. So if I were to make an unedcuated guess, I'd wager that there's something wrong with the DX9 -> Windows 11 implementation, and that same issue is present in the DX9 -> Vulkan/WineD3D implementation. Most noteworthy, whatever the dgVoodoo creator did that fixed it for windows 11, also works to fix it for Vulkan/WineD3D. It's just the game crashes intermittently using his dll hack. I don't have any more information on the source of the problem beyond that, though.

So can reproduce this if i use dxvk 1.7. But not when using proton 7.0-2 (dxvk 1.10.1), 7.0-3RC or dxvk 1.10.1 from github.

Hmmm... so maybe this is not something dxvk specific after all, but rather an issue fixed by a Proton hack. That would explain the above, since I assume @K0bin is using Proton, while I am on Wine Staging.

@WinterSnowfall Which driver do you use?
This seems like a floatEmulation issue, since i can reproduce it if i change it to true. dxvk changes it to strict by default if you use radv/mesa 22 or above. strict wasn't a option in dxvk 1.7 yet.

I thought everyone knew by now I'm an Nvidia peasant :). I currently have a GTX 1080 on my main gaming rig and an Intel Xe Graphics powered laptop at my disposal.

Alright, let me give it a shot. Thanks for the tip :+1: .

My memory is shit xd.

Once you've verified d3d9.floatEmulation = Strict work we can make a pr.

Yes, that fixed it :partying_face: . @Blisto91 please prep a PR for launch :rocket: . Both the original game and Forged Alliance have the executable named SupremeCommander.exe so this should fix the issue in both games, which is perfect.

:tada: :+1:

Do you know if supreme commander 2 have similar issues?

They dropped the fancy warp-in effects at the start of the game in SupCom2, so there's no really easy way to tell... and I no longer have a Windows machine around to compare it against otherwise, unfortunately.

Rgr. I will make a note of it to check later if i get the game.
