Summary0002012: Game not displayed correctly
DescriptionThere are some graphics issues on my laptop. Graphics crad is a rather new GeForce 940MX, drivers are up to date.
From log: [00:07:14] GL 3.2.0 NVIDIA 391.01 on GeForce 940MX/PCIe/SSE2 (NVIDIA Corporation)


First, the colors are off. They are too bright and look washed out. See screenshot. The main menu looks like this, too. Screenshots made with F9 have normal colors. Starting a round in editor mode also gives normal colors.

Second, there is sky showing through material borders. Also see screenshot. This issue is also apperent in editor mode. I suspect antialiasing having to do with it. Maybe I can fix this by going into the Nvidia control panel, but I'd prefer if it would work out of the box.

Third, the shadows of the FoW are too hard? It's hard to tell, but especially the clonk's light cone has a hard edge.

We had problems like these in the past. But I can't remember what we did about it. I'll have to investigate.

Did you enable any application overrides in the NVIDIA control panel? I think these overrides caused similar issues in the past.

Pyrit (developer)

After setting everything to Off or "Anwendungsgesteuert" in the Nvidia control panel, the artifacts on material edges are gone. But so is the antialiasing on the 3d game objects.
It is weird because I cannot choose the antialias option ingame. It is hard set to Off, with no option to enable it in the options menu.

The color problem and the FoW problem still persist.

So apparently there's a bug in the code that reads multisampling modes from OpenGL on Windows. We cannot do anything about driver overrides for antialiasing and other settings. After all, the whole point of these is to ignore what the application sets.

Not sure about the colors. Screenshot rendering does exactly the same things as normal rendering, so I suspect this is some modifier on the game window by Windows / set by some third-party application?

They might not contain the global gamma, right? I think that I had to edit screenshots from ClonkRage scenarios back then, because the lighting was off in screenshots compared to the actual game

Yeah, the brightness definitely looks like something is adding gamma to the game. And yes, I think that would not be present in Screenshots.

Gamma is now applied in the shader [1]. OpenClonk doesn't touch monitor gamma anymore like CR did. (Or at least it shouldn't...)
