Testers and reviewers wanted: BFG-style vertex cache

[HMart]

I also don't see shadow maps for alpha materials, but i assume that is caused by material keywords like noshadow, backSided, DECAL_MACRO and twosided that disables shadow casting.

 

Also that shadow mapping softness at the distance is because duzenko implemented "Contact Hardening" shadows, the closer to the object, the shadow is, the harder it gets! sounds dirty ;p

Can you try using a core profile GL context? It allows a more recent GLSL version on Intel (on my system).

Regret not in TDM 2.07.

Try forcing r_useGLSL 1 in game console.

Update 12 is here:

 

https://www.moddb.com/mods/the-dark-mod/downloads/tdm-206-vertex-buffer-beta

 

* A new texture atlas system for Shadow Maps significantly improves resolution management and LOD

* Improved Softening for Shadow Maps

* Almost all shadow acne has been solved and the remaining artifacts are very minimal.

 

 

Note: The softening has improved to the point that you can lower r_softShadowsQuality to 14 or lower and still

have very smooth shadow transitions in most cases.

Performance JUMP!

SoftStencil: 48 FPS

ShadowMaps: 55 FPS ( BUT WHY THE WEAPON DISAPPEARS? )

VideoRAM increased and CPU usage too.

But a nice jump of 7-8 FPS in that scene! (15%)

Old "contact" issue with the shadowed object (there's NO contact with radius 1 too )

@nbohr1more

Do we want to rename this thread to 2.07 alpha testing or something?

@nbohr1more

Do we want to rename this thread to 2.07 alpha testing or something?

Does this mean that 2.07 will be moved to the D3 BFG engine?

[nbohr1more]

2.06 has hybrid vanilla and BFG code, with mostly vanilla code and dhewm changes.

 

2.07 will move closer to BFG.

 

We are picking and choosing the features we like from various Doom 3 (and BFG) branches and integrating them

along with our own code design changes.

[peter_spy]

I don't know about you, but switching to r_shadows 2 makes fans on my GPU go pretty loud, and the performance isn't always better.

Update 14 is here:

 

https://www.moddb.com/mods/the-dark-mod/downloads/tdm-206-vertex-buffer-beta

 

 

 

 

 

Some major upheaval and improvement took place since the last update.

 

Soft Shadows now use a substantially improved PCSS calculation courtesy of stgatilov

 

Also, there is always a minimum amount of softening as a way to obscure aliasing artifacts

at the low resolution bounds of the shadow map.

 

In short, shadows are more physically correct, better looking, and almost all aliasing artifacts are

hidden.

 

Also, tentative work has been done to setup per light-entity light center size attributes so different lights can have different amounts of softening.

 

For the shadow map softness, the slider will no longer work as the override is now a negative number.

 

Recommended settings:

 

r_shadows = 2

r_testARBProgram = 1

r_softShadowsRadius = -0.65 or 1

r_shadowMapSize = 1024 or 1440

r_softShadowsQuality = 24 or greater

 

Note: You can even go lower on the Shadow Map size due to the new minimum shadow softening feature. Give it a try.

[lowenz]

Awesome final result! NOW there are no more contact artifacts!

(Do shadows are clustered-calculated or per-object/mesh?)

One omni-directional shadow cubemap per light, all lights in one shadow texture - assuming you're on r_shadows 2

[HMart]

In the new 14 update shadow maps to me became totally burked, i tried both 32 and 64 bits exes.

[nbohr1more]

Cvar settings?

[HMart]

The ones you posted above.

 

r_shadows = 2

r_testARBProgram = 1

r_softShadowsRadius = -0.65

r_shadowMapSize = 1024

r_softShadowsQuality = 24

 

 

r_softShadowsRadius is a negative number?

 

Btw i installed duzenko latest volumetric test shaders and exe and shadow maps started working...

Did you clear shader cache?

 

Does the problem return if you go back to update 14?

I don't know how to do that. Do i just delete the shaders folder?

No it still works.

C:\Users\%userprofile%\AppData\Local\AMD\DxCache

is where cache data is supposed to reside, from a little googling. Similar path for nvidia

but it's under AppData\local\Temp\Nvidia...

The volumetric branch should have all the svn changes merged as well

Not only!
