[Call of Cthulhu: Dark Corners of the Earth] - Windowed Mode brightness issues
Enabling windowed mode is a god-send as it prevents the game from crashing when alt-tabbing. Unfortunately, it sets the brightness to 200%, and the in-game brightness menu ceases to function.

Tested with the latest stable release of dxwrapper on retail edition (same as Steam, I believe) and GOG version. Let me know if there's anything I can do to help out - and thank you for your efforts on this project.
That is probably a Gamma issue. Gamma in Direct3D9 and older does not work in Windowed mode, even fullscreen windowed mode.
I could use either a shader or Windows gamma. A shader will take longer. Using Windows gamma will affect the whole screen not just the game window.
It looks like just the game world is affected. https://i.imgur.com/69LIBPD.png https://i.imgur.com/D2fLQDl.png
No luck, unfortunately.
Below is what I tested: FIles copied as is: alt-tab crash +FullscreenWindowMode: alt-tab crash +EnableWindowMode: alt-tab crash -Dd7to9: alt-tab crash renamed ddraw.dll to d3d9.dll: alt-tab crash +EnableD3d9Wrapper: same gamma as before. brightness menu has no effect.
Let me know if I've made a mistake somewhere here.
It is weird that it crashing in Alt+Tab when using windowed mode. That should not be because in windowed mode the device is never lost. Maybe the game uses a combination of DirectDraw and Direct3D9? In that case you need to disable dd7to9.
Here is an updated one where I moved the gamma feature to the Direct3D9 wrapper. Try this one: dxwrapper.zip
Hi Elisha, Gamma is the same as before, but now the brightness menu works. :) It crashed when alt-tabbing, so I turned on EnableWindowMode.

Which gamma are you referring to that does not work?
It crashed when alt-tabbing, so I turned on EnableWindowMode.
Is this a bug in the game? Does it crash without dxwrapper when you do alt+tab? My Direct3D9 wrapper just returns the calls directly from Direct3D9, so it should not have any issues here.
Hi Elisha, Yeah, the alt-tab crash is a known bug with this game. Your wrapper's Windowed Mode resolves it. Only problem is gamma for the game world is twice as bright as it should be.
Hi Elisha, Just tried the latest dxwrapper release and the D3D9 Windowed Mode gamma issue seems to be fixed. Great work! That said, the in-game brightness menu no longer works when in windowed mode. Any chance you can have a look at it? (You fixed this pretty quickly last time).

Yes, this is a known issue with Direct3D9. Supporting Gamma with Direct3D9 in windowed mode requires either a swapchain or a pixel shader. I don't want to use swapchains as this can cause other issues (example with Nvidia's RTX Remix). At some point I will add a pixel shader for this. But that won't happen for a while.
Edit: I can also do this by using Windows Gamma controls. But that causes other issues with certain games as well as causing the whole screen to go bright or dark rather than just the game window.

No worries. Happy to test when it's ready.
Experienced a lot of rendering issues (walls not showing, blinding lights, etc.)
Previous dxwrapper (Dec 14 Release):
From what I could tell, the in-game brightness menu did seem to be working at least.
Yep. That did the trick. Windowed Mode brightness is as expected, and the in-game brightness menu works. Thank you for looking into this :)
