Eliminate Jaggy Shadows?

[ryanbatc 12,812]

I think whenever I turn on ground shadows I get these horrid jaggies on the planes.  Does anyone else see this?  Is there a fix?

This is with the latest XP11.30

Hi Ryan, you can try do some search shadow fix plugin in org forum, i forgot what is real name, recently i download the file and it fix my jaggy shadow issue, it a plugin not lua script if i am not mistaken.

This always bugged me. 

The jaggies become worse as the sun gets lower in the sky.

Nice to know there is a work around.

 

Thanks for the info,  Muhamad.

sorry my mistake, it is lua script, not plugin, i confuse with fpm plugin. the lua script is shadow.lua in x plane forum

You need a beefy system. The jagged shadows are a simplification to help performance, not negligence.

A good system, not a beefy system.

At least Laminar should make an option to have unjagged shadows fot those who have a good system.

I don't think it's that

Ground shadows OFF the jaggies go away on the aircraft.  Ground shadows ON gives me the jaggy shadows.

Plus the machine I'm using is Linux with a 7700K and GTX 1070 ti 16gb ram

I agree with Paul above, that what you're probably seeing is the sim trying its best to show you both ground shadows and plane shadows, and your rig just isn't able to do both equally smoothly and anti-aliased. 

Ground shadows are a major performance hog. My rig isn't enough to run them. You need seriously beefy hardware to do it, especially if you're running a monitor res higher than 1080p.

Laminar does that very well for plane exterior and cockpit shadows. But ground shadows are a whole different proposition. Look at a forest, and every tree will have its own shadow! That's a massive hit on your hardware.

Play with your AA settings.  I maxed mine and the jaggies went away.  Also turn off ground shadows, for some reason ground shadows caused jaggies for me.

That's the whole point...this only happens when ground shadows are on.

Don't look at the plane from the outside?

Check this out. It really helps reduce or eliminate jagged shadows:

Hi Ryan,

It is just speculation but maybe there is a bug indeed, or just that there is a single shadow map, therefore, when using both ground and aircraft the single shadow map has to 'bake' a wider area than when just baking the aircraft shadows alone, thus, the shadow map resolution gets lower and the jaggies show up.
