About STALKER: just put the d3d9.dll (in the bin folder + bat for launch the engine from the root - work - dir) as always.
It starts with no problem but only with static lighting available no matter what you choose in the menu.

So, any idea about this behaviour?

Note: I've already removed from the bin folder "d3dx9_31" and "d3dx9_34" maybe interfering

Shadow of Chernobyl 1.0006, no mods, game starting area

NO dgv2 (right rendering for "Full Dynamic Lighting"):

dgv2 "forced" static lighting no matter the menu choice:

(The dynamic sun-related shadows and the different terrain texture confirms the different lighting model used)

Indeed, thanks!
I don't yet have any idea. Maybe a "caps" problem again or sg like that, still subject to solve.

DXVK 1.8.1 working right (just reporting) in STALKER SoC.
90% "native" d3d9 driver performance

Ok, as it turned out, the game initializes D3D9 from both DllMain and later from regular code.
DllMain fails with dgVoodoo and that's what causes losing dynamic lighting (I guess the game queries some caps, texture formats and such from the DllMain instance).
Experimentally I forced DllMain to fail with native D3D9 and got the same wrong result.

So, I'm afraid dgVoodoo won't work with this game unless the game is patched (if possible at all).

This is a good thing ? (Open X-Ray implementation -> https://ci.appveyor.com/project/OpenXRay/xray-16/history )

Yes, that change should resolve the problem.

Well, let's wait a stable release of OpenXRay then!
Will test OGSR too ( if you wanna take a look, OGSR is specifically intended as a "drag&drop" SHoC engine replacement! -> https://github.com/OGSR/OGSR-Engine )

The Steam version of S.T.A.L.K.E.R. got a patch a year ago which addressed Dynamic Lighting not working on Intel Graphics (they run D3D9On12 internally). This patch also makes Dynamic Lighting functional on dgVoodoo2.

Well, now Intel GPUs have a proper D3D9 driver 😁
