Old "standard" fog mode as an option

Post by phi108 » Fri Jan 06, 2012 2:31

The Standard fog mode has been updated to behave similarly to how "radial" behaved once, or is acting similarly now. "Radial" mode always has caused fps lag when opening doors into new rooms. Now the "Standard" setting does it too, as I guess it brightens the area around the player like a lightbulb. There is now no way to enable fog without door opening lag on my system, so an "old Standard" fog mode would be welcome.

Is this related to GL_fog_shader? That setting has no effect, so I think it's from the shader options list that doesn't show up on every System.

You are looking in the wrong setting to disable it.
The brightening around the player is detemined by the Sector Light Mode, not the Fog mode.

Also, what hardware do you have. In response to 'it runs bad on my hardware' my standard response would be 'you have bad hardware'. The entire thing gives me no issues whatsoever on my 4+ years old system with a Geforce 8600GT.

The door lag occurs on every Sector Light mode with fog on, but not when Fog Mode is set to Off.

I just tried the old Skulltag renderer with "shaders for fog" turned off, and it solves the problem. If GZDoom had this option available or if the console command had an effect, that might fix it.

Hm...

Budget DX10 chipset. That's a problem. Can you try starting GZDoom with '-sm3' on the command line?

That solved the problem, Standard fog mode now has no problems, though it did disable "Doom" sector mode and radial fog mode. Does the new Doom mode act differently than in old versions and Skulltag? Dark sector mode seems adequate though for me.

Doom mode is basically Dark mode with a shader-based brightening around the player.

... and since the problem here is obviously shader performance it will cause problems.
