Tessellation

[baggins183]

Opening PR for testing, not close to merge

Only post results from this fork
https://github.com/baggins183/shadPS4/tree/tess

I know about the "Failed to create graphics pipeline" error on AMD, so dont post about that unless youve debugged the vkCreateGraphicsPipelines call and found something or can spot problems in the code.

Needs testing in other games that have tessellation shaders.

Also for BB, if someone can narrow down the hs_* and vs_* (domain) shaders responsible for blood splatter on clothes, or snow at cainhurst, that would help. Ive done some Cainhurst debugging with no luck so far. I can't confirm if its a tess problem or not.

[baggins183]

for amd bros who are crashing it would be interesting to know if some pipelines using tessellation shaders do compile successfully or if all of them cause the vkCreateGraphicsPipelines error

[baggins183]

I think if you can get a shad_log that has 2 or more "compiling hs shader"s that would be good.
If you are also crashing with failed to create graphics pipelines

Thank you for your efforts, mr. Baggins. Here is my log:
shad_log.txt

[Mast3rwaf1z]

Linux AMD GPU:
This pr works perfectly on the RADV driver (ignoring the unrelated issues RADV has with the emulator already), but with the AMDGPU_PRO driver (which is the only way to play on the emulator on AMD on linux atm afaik) , the emulator will not load the game at all on the appimages, and when i compile it myself it gets to the title screen but doesn't load into the game.

I think if you can get a shad_log that has 2 or more "compiling hs shader"s that would be good.

0 lines in all 3 log files, my guess is it might be platform specific?

Logs:

the ones where i get ingame are too large to upload here. I have attached when i'm running BB using AMDGPU_PRO, using https://github.com/ngoquang2708/shadPS4/tree/linux-hack-tess, which is based on your branch
appimage.log

No, if you hit tessellation shaders you would see this in the log. Check your log filter and that u have sync logging.

You dont have to use and shouldnt report problems with forks. It looks like that fork is out of date

[Foul-Tarnished]

Does this have #1538 ?
A rebase would help with testing BB I guess?

[baggins183]

rebased

for AMD crashes on failed to create graphics pipelines id actually recommend skipping the last "hs shader" hash you see your log (adding the hash to shouldSkipShader) to see if there are other tess pipelines that compile successfully.
If like i said you see >=2 "Compiling hs shader"s in your log then let me know, because that would mean some compile successfully and theres an isolated issue with certain shaders.

example:
[Render.Vulkan] vk_pipeline_cache.cpp:CompileModule:461: Compiling hs shader 0xbc234799

[GHU7924]

Build 664e61f
I have a save in Forsaken Cainhurst Castle.
I did a little run there.

Unfortunately, I did not see this in my log.

I had two lines of shaders or more:

And so forth.
P.S. If I didn't tell you something new and useful, then I apologize.

[baggins183]

if you were crashing before and this did or didnt fix it let me know your gpu, driver, and OS. Also whether your on proprietary or radv drivers or whatever.

[baggins183]

also make sure your game is unmodded. I dont know anything about sfx mods

[artixomag]

Amd Gpu 6700 XT with driver 24.20.19 on Windows, the new tess build works and displays all the effects.

[baggins183]

just a rebase

[ArbestRi02]

i think we should rebase again considering the recent progress on main

[rafael-57]

If you're going to rebase, since more-kernel has been merged, this hack shouldn't be needed anymore

[Foul-Tarnished]

Is there a way to skip shaders with this PR ?
For #1547 workaround

[rafael-57]

It seems people merged this on top of current main and found that tess works in Dark Souls 3 too:

Without tess. lots of effects don't work.

So yeah it's a very similar game to BB, but at least we've found another game that uses tess. :D

@baggins183 Due to the recent changes to main I think it would make sense to rebase again. Thanks a lot in advance!
