The problem is depth stencil sharing with multiple render targets. Depending on
your offscreen rendering
method(HKEY_CURRENT_USER/Software/Wine/Direct3D/OffscreenRenderingMethod) you
get different results.

With the default backbuffer, the whole game is broken, even without night
vision

With pbuffer it is untested, but expected to be broken too

with fbo, the normal rendering works, but the nightvision fails because the fbo
does not have proper stencil support yet, and because the transfer from the
onscreen depth buffer to the offscreen depth buffer is not completely right.

Flare completely hiding scenery behind light source

In this view the illuminated scene is completely hidden by the flare from the
light source.

Weaker flare, turning away from first view

This view is turned slightly from the previous view, and the flare is weaker so
the underlying scenery becomes visible.

I've added two attachments showing what may be a related visual bug, where the
flare from light sources completely overwhelms the scenery.  Light sources show
through many layers of the scene, it's very strange.

This is with wine current (from git) as of half a dozen hours before the time
of posting, with fglrx (ATI Radeon 1650) on Ubuntu 8.04.

Apart from the difficulty of coping with holes in the scenery created by flare,
the game is quite playable.  However, the night vision view is completely
unusable.

I have more "glitches" in the full version. A lot of error messages on the
console as well, attaching some logs and screenshots.

I have UseGLSL set to disabled and OffscreenRenderingMode to fbo.

It's not only the shadow rendering not working, but also the normal rendering
(see screenshots).

Cheers,
Tobias

The current state of play (version 1.1.10, ATI Technologies Inc Radeon X1650
Pro graphics card, current ATI drivers, Ubuntu 8.10) is pretty bad:

1. In normal vision the only thing visible on the screen is a bright flare from
one light source, everything else is black.

2. If night vision is enabled then I can see, and things are smooth -- but
sections of the display are badly scrambled.

3. Full screen mode is badly broken, only get a quarter of the menu, in the top
left hand corner of the screen.

1) You have to enable fbos, backbuffer will never be able to run this game
properly

2) Stencil buffer support with fbos is missing

FBO was on with all my tests, the game still looks pretty ugly.

I found some option called EmulateGF2Mode in the SplinterCell.ini
(D3DDrv.D3DRenderDevice section) which smoothes rendering. Of course the lights
still shine through the scene.

What would need to be done to get this working? Some hints in which files to
look?

What needs to be done is supporting D3DFMT_D24S8 depth stencil buffers with
GL_EXT_packed_depth_stencil. That would probably affect utils.c, surface.c and
device.c. What is important is to keep the ability to use those surfaces as
depth-only buffers if the extension is not supported(many games request D24S8
but only use the depth buffer part)

I intend to work on this. If possible Stefan, could you give me some pointers
where to start? I have already skimmed through the packed_depth_stencil
extension docs and have a rough understanding how it works / why it's good to
have support for it.

Sadly I lack some starting points (the unimplemented features don't trigger any
FIXMEs or similar debugging code).

David_A on IRC wanted to look at the same function, perhaps get in sync with
him before you two do the same work independently.

Basically you have to set the format from the extension in the GL pixel format
template in utils.c, and set the GL_STENCIL_ATTACHMENT_EXT to the same
renderbuffer or texture in context_attach_depth_stencil_fbo in context.c

There are a few things that make it slightly(not much) more complicated:

*) We want to be able to fall back to the current stencil-free operation if the
extension is not supported. So have a fallback that uses the stencil-free gl
format in the InitPixelFormats function(or a similar name) in utils.c

*) There is no way to set a stencil attachment != the depth attachment on most
drivers(that just means no stencil fbos without that extension. With the
extension they have the same ID, so things are fine)

*) Avoid comparing the format against D24S8 in
context_attach_depth_stencil_fbo. Instead, create a new pixel format flag and
check for the flag in this function. Using this flag you can easily fall back
to the stencil-free behavior if the extension is not supported.

It's attached to bug 6351, but it's not specific to that bug, it's just a
merged patch for ARB_fbo support. The problem is that not all drivers that
currently support EXT_fbo also support ARB_fbo.

I would very much like to test this, but my mainboard is still in repair.

I tried master on my Intel card, but sadly this crashes the whole xorg-server -
not a bug in wine though I think.

Tested this wine fresh wine git master (1.1.23 doesn't work for me in
combination with 3D apps).

The glitches are almost gone, but they are still some lights that shine
through.

However I'm not longer running this on my old FX5900, but on a integrated
Radeon HD3200 (RS780 chipset, flgrx drivers). fglrx also seems to support
ARB_fbo, so I don't know if it would also look better on drivers that only
expose EXT_fbo and EXT_packed_depth_stencil.

hi there, im running the game with a radeon 3850pro, and ive got the following
glitches to report: Lights shine through solid objects, the screen doesnt
resize correctly after videos (possible workaround: when completing a mission,
as soon as the screen turns green go to the graphics menu and switch resolution
to 640x480; after video sequence change the resolution to desired value again);
trying to run the game in fullscreen killed x-server, virt. desktop is a must.
and last but not least: no moving lights (flashlights, search beams) are
displayed, this is my biggest problem atm.

Wine can not kill x-server. It is a bug in your graphic card driver. Report the
bug to your GC manufacturer

The light-shine-through issue is still present. Apart from that the game looks
good :)

Tested on:
00:02.0 VGA compatible controller: Intel Corporation Arrandale Integrated
Graphics Controller (rev 02)

Driver: i965 mesa classic (git master)
wine-1.3.1

And yes, this GPU (according to glxinfo) supports ARB_fbo.

I'm seeing this bug with Wine 1.3.12, SC 1.3 [0] (which works fine with the
3-CD version or to put it differently: version 1.2b shows the same graphical
corruption) and a R300-based graphic card (r300g, Mesa 7.10 (Gallium 0.4), DDX
6.13.2, X 1.9.4 RC2, Linux 2.6.37 with KMS).

As the screenshots ([1-12]) show, all screens except the loading screens have
issues.

I've tried to set OffscreenRenderingMethod and UseGLSL with their different
settings (in all combinations) to no avail and also tried to set
EmulateGF2Mode=1, again, without any changes.

There is nothing logged (except endless lines of
fixme:dsound:IDirectSoundBufferImpl_AcquireResources), if you need some special
debugging channel, please let me know.

See bug #24276. Henri's patch is still not in git. Could this one be finally
pushed to master?!

@Cùran: Can you comment on your settings? I'm interested what you've selected
for ForceShadowMode and EmulateGF2Mode.

The only (somehow) working combination for me is ForceShadowMode=1 (shadow
buffer) and EmulateGF2Mode=1.

----------------------------------------------------------------------
> From "Tom Clancey's Splinter Cell - Patch 1.2 Info/Changelog"

++++++++++++++++++++++++++++++++++++
DETAILS – BENCHMARK MODE / SPLINTER CELL DESIGN

The Splinter Cell benchmark mode was a tool created to validate our performance
optimization in the engine. This tool can be especially useful to determine the
performance of a specific PC configuration (GPU and CPU). 3 demos are included
in this release (1_1_1TbilisiDemo.bin, 1_1_2TbilisiDemo.bin,
2_2_1_Kalinatek.bin)

Some basic understanding of the Splinter Cell renderer and settings are needed
to accurately use it as a performance analysis tool. UbiSoft does not support
this feature at the consumer level but will answer questions asked by hardware
reviewer magazines or OEMs.

Splinter Cell has 3 different rendering pipes:

Class 2 Graphic Adaptors:
NV2x/NV3x chips
Dynamic Lighting system = Shadow Buffer
Vertex position modifiers = Yes
Light beams stopped by depth texturing = Yes
Pixel Shader effects/filters/water = Yes
Reflection/Details texturing/Specular = Yes

Class 1 Graphic Adaptors:
R2xx/R3xx/Parhelia/Xabre 200/Xabre 400/Xabre 600/chips/Creative P9
Dynamic Lighting system = Shadow Projector
Vertex position modifiers = No
Light beams stopped by depth texturing = No
Pixel Shader effects/filters/water = Yes
Reflection/Details texturing/Specular = Yes

Class 0 Graphic Adaptors:
R1xx/NV1x chips
Dynamic Lighting system = Shadow Projector
Vertex position modifiers = No
Light beams stopped by depth texturing = No
Pixel Shader effects/filters/water = No
Reflection/Details texturing/Specular = No

Class 2 adaptors can run as Class 2, Class 1 or Class 0 adaptors while Class 1
adaptors can run as Class 1 or Class 0 adaptors. Class 0 adaptors are only able
to run Splinter Cell as Class 0 adaptors.
You can force a class 1 or class 2 adaptor to run as a different class by
editing the splintercell.ini file in the \system directory. Uncomment
“ForceShadowMode = 0” to force the card to run as class 1 adaptor (if able to)
or change “EmulateGF2Mode=0” to “EmulateGF2Mode=1” to run as a class 0 adaptor.

Why does Splinter Cell have a special mode for NV2x/NV3x graphic chips?

Splinter Cell was originally developed on XBOXTM. Features only available on
NV2x chips were used and it was decided to port them to the PC version even if
these chips would be the only one able to support them. Considering the
lighting system of XBOXTM was well validated, it was easy to keep that system
intact.

Splinter Cell Dynamic lighting system

Splinter Cell shadow system is a major part of the game. On NV2x/NV3x hardware,
it runs using a technique called Shadow Buffers. This technique is rendering
the scene from every shadow casting light and store a depth buffer that
represent each pixel viewed by this light source. Each pixel has an X, Y, Z
coordinate in the light system and these coordinates can be transformed, per
pixel, in the viewer coordinate system. It’s then easy to compare with the
actual depth stored in the Z buffer to figure out if the pixel viewed by the
camera is the same or is occluded by the pixel viewed by the light. If they are
the same, it means the pixel is lighted, if the light pixel is in front of the
viewer pixel, it means the pixel is in the shadow. On all other current
hardware, the game is using another technique called projected shadows (shadow
projectors). The technique is somewhat similar, we render the scene from the
light point of view but instead of storing the depth, we are storing the color
intensity in a texture. That texture is then mapped per vertex on each object
that is going to receive the shadow. To be able to have objects casting shadows
on other objects that are themselves casting shadows, Splinter Cell is using a
3-depth levels shadow casting algorithm. In general, the first level is used to
compute the shadow to be used on the dynamic actors like Sam. The second level
is used to compute the shadow used by the static meshes like a table or boxes.
The final level is used for the projection on the BSP. This system is allowing
Sam to receive the shadow of a gate on him, then Sam and the gate can cast on a
box and finally all three objects can cast on the BSP (ground). This system
also has a distance check algorithm to determine if Sam’s shadow should be
projected on a static mesh (like a box) or if it shouldn’t base on their
relative position. Both systems have their own strength/weaknesses. The main
advantage of the Shadow Buffer algorithm is how easy it is to work with. Shadow
Projectors are tricky and difficult to use.

--- Comment #40 from Cùran  2011-02-03 12:46:39 CST ---
First as an update to comment #37: The game looks good except some minor
glitches like flickering textures, some lighting seems to be off (like
attachment 13441) and probably a few other things I haven't noticed.

In reply to comment #38 and comment #39:
I use the default settings of Wine and SC also uses its defaults, excerpt from
SplinterCell.ini:
> ; ForceShadowMode flag : 0==projector, 1==buffer, unspecified==auto-detect
> ;ForceShadowMode=0
> EmulateGF2Mode=0

The system I'm playing this game on is detailed in comment #35.

Wrt bug #24276: The patch mentioned there would just add a warning in case S3TC
is required and not available, right? Would help to catch my initial problems.
Yes.

Can anybody comment on the status of the patch in attachment 20674 and whether
it should fix the remaining glitches? If so, I'd be happy to test that.

--- Comment #41 from Tobias Jakobi  2011-02-15 05:25:58 CST ---
Can now also test this on my RV740 with r600g (s3tc support was added):

1) The light-shine-through issue is still there
2) The only configuration where shadows are working is with EmulateGF2Mode=1.
   As long as this emulation mode is enabled, it doesn't matter whether
   I select shadow projector or shadow buffer mode.
3) Shadows show z-buffer issues / z-fighting

@Cùran: Are you really sure that it works with r300g and EmulateGF2Mode=0
(disabled)? Because this would indicate a problem with r600g.

Yes I'm sure. I've pasted the relevant lines in comment #40 and didn't edit
them for the comment (Where would be the point in that? Wouldn't help.). In
fact I didn't edit SplinterCell.ini at all, so what I have in there is what the
game set.

I could just paste the whole $SPLINTERCELL_INSTALL_DIR/system/SplinterCell.ini
though you'd still no guarantee I didn't mess with it. So I don't see the point
of that. Same goes for screen shots.

The last comments were about the lack of ST3C support in mesa driver. It is not
a Wine bug.

You need to be very specific about graphics driver here.  I've just reported
bug 30576 which turns out to be, mostly, missing ST3C support, but even with
that enabled the game looks awful.  Looking upstream in this bug report,
particularly #39, it looks like the game itself explicitly behaves differently
on different cards (oh dear), so to say "it's fixed" is a bit optimistic.

For me the game looks dreadful, both due to the flare of lighting and fractured
textures through busted ST3C.  My card is an HD 6950, my driver ati (not
fglrx).

Hello. I've got similar problems like shown in "Splinter Cell full 1.2 -
screenshot from in-game" with allmost all the Splinter Cell titles. Seems to be
some lightning issue, notacibly mostly on level starts or reloads, probably due
to renderer reinitialization. The problems are still there in recent git.

I'm on an Intel Q6600 with an NVidia 9800GTX

set it to "disabled"

Hmmm. Do you have a controller plugged in while running the demo?

Also, this might be a long shot but can you try temporarily disabling all the
xinput dlls in winecfg to see if the out of control spinning goes away?

Hello,

The bug is too generic and has become messy with multiple issues, it should
die.

The first identified issue about FBO stencils is fixed per comment 29 to
comment 31 so, marking this bug FIXED by commit
f8c4832276fb740e527fed87aa27975f91546d26.

The remaining issues should be reported separately, if not already done.
