Shadow Flickering: (1.7.10)Optifine U E7 And FastCraft 1.25

[jahtim]

(BUG SUBMIT: Shadow Flickering )

(1.7.10)FastCraft 1.25 And Optifine U E7 player shadow broken.

When installed FC 1.25 and Optifine U E7, every shader pack has a same problem:

When the player is falling, the shadow of the player is flickering, thus , some frame the

shadow of the player is vanished, and maybe next frame the shadow is out there again. The result is a flickering shadow of the player when falling. But when the player is running or using a jetpack, all things fine.When the player is jumping, the first half of the jumping is just fine, and when the player start to fall, the shadow of the player is abnormal.

I tried asyncculling = true or false, turn on vsync and off, turn on or off the old lighting, shader options and almost every config I Have and still cannot solve the problem.

I tried Use Optifine U D6 and shadermod instead of Optifine U E7. It works just fine with FC 1.25. But fps decreased by 50%.

I tried Optifine U E7 without FastCraft 1.25 and the shadow is fine. But fps decreased about 25%.

I Use Forge 1.7.10 1614, win10 laptop, Graphic Card Nv GTX 1060

(this gif is not accurate, the shadow of the falling player is flickering actually)

Guys do you have any workaround? I found this super annoying and killing my eyes if I am moving really fast/creative flying, That is a really common case if you are playing with TC4's Traverler's Boots or IC2 Quantum/Nano Suite.

I have a beefy GPU + 165Hz monitor so I really don't wanna give up the immersive experience from shaders. But it is FastCraft that enables the game to run this like >120fps.

So my choices are:

1. Giving up FastCraft and ~20fps
2. Use Optifine alternatives like Angelica, but this is like super early alpha stage, getting crashes randomly.
3. Disable all shadow by setting shadowResMul=0.0, which is like disabling 50% of the scenery

Ideally A better workaround could just be turning off the player's shadow to get away with the fast changing flickering shadow. The closest config I found was

# Enable or disable rendering of entities in the shadow pass
shadowEntities=true|false

But this one only disables shadows of other entities not the player itself...
