Question about new transform feedback support: Metro LL still gets "Rasterized stream not supported"..

[oscarbg]

Hi, with a quick test on 0.9.0+ new NV drivers I see Unity Adam demo is rendering correctly finally!! and Metro LL launches now without: d3d11.fakeStreamOutSupport = True

but in MetroLL_d3d11.log

errors before were:

err:   D3D11: CreateGeometryShaderWithStreamOutput:
  Transform feedback not supoorted by device

now are:

err: D3D11: CreateGeometryShaderWithStreamOutput: Rasterized stream not supported

so question "Rasterized stream not supported" is because VK ext. limitations or DXVK limitation? thanks..

Are you using patched Wine? Wine upstream didn't catch up to it yet.

[doitsujin]

Simultaneous stream output and rasterization is currently not supported in DXVK. The Vulkan extension allows it, but it's somewhat painful to implement, and I wasn't aware of any game that needs it.

Given that both versions of Last Light have native Linux support I'm not sure if I really care though. Was this with the original version of the game or with the Redux version?

[oscarbg]

@shmerl using patched Wine.. @doitsujin original version.. not really a problem, as you say Redux versions have native Linux binaries.. anyway good to know Vulkan ext. supports simultaneous stream output and rasterization anyway.. Closing..

Toukiden Kiwami show this:

err: D3D11: CreateGeometryShaderWithStreamOutput: Rasterized stream not supported

Nioh shows this as well.

[doitsujin]

They might show it, but I haven't seen a single game which actually requires the rasterization so far (it's not very useful anyway since it only supports points, not triangles). Some games specify a rasterized stream but then choose not bind any render targets, or even write to SV_POSITION in their geometry shader.

[psy-q]

Ah, thank you for clarifying. That's rather odd behavior from the games' side, then. I'll keep my hopes up for Nioh one day :)

[doitsujin]

afaik Nioh is being held back by wine issues.

I had the same error while playing Dead or Alive 6. It seems that is this error that prevent me to play, other people can (except the story mode). err: D3D11: CreateGeometryShaderWithStreamOutput: Rasterized stream not supported

[doitsujin]

No, it isn't.

[root2185]

Why can't I play then?

[doitsujin]

Don't know? Also, please don't hijack unrelated issues.

@doitsujin now that nioh semi-works I noticed weird issues with transparency effects and was wondering if it's related to stream rasterization? Mostly happens when things fade in/out, for example for the guardian spirit in the main menu when you press "Continue". I tried to capture it but it's not extremely obvious:

Basically transparent objects have a strange dot pattern on them. I don't have access to windows so I scanned through youtube videos and didn't notice it in this video:

Sorry if it's not the right place to post, please let me know if it will be better to track this as a separate issue.

[doitsujin]

No it's not related. If you think this is a bug, please record an apitrace and then open a new issue.

[psy-q]

@ap4y The effect is also there on Windows. There is a similar one when e.g. a door or other solid object is between your character and the camera, the closer it is the more it dissolves into dots.

[ap4y]

@psy-q ok, thanks for confirming that. it's not a big deal, just looks weird.
