f8d29fdc1a GPU: Simplify depth clamped clip planes. 
There's no need to think about the scaled Z if we're using w anyway, just
use the existing Z clipping.

2fc7f72d72 GPU: Clip clamped depth accounting for perspective. 2022-09-20 15:55:39 -07:00

a2a7e8258b GPU: Clip depth properly when also clamping. 
Helps situations like #11216, where only one side should be clamped.
Keeps depth clamp (i.e. #7932) working.  See #11399.

e56e5947d5 Vulkan: Declare gl_Position as invariant. See #11583 
The code that computes shader outputs declared as invariant gets certain
optimizations disabled that could change the value - it makes it more
likely that different ways to do the same calculations end up with the same value.

This can help some types of Z fighting problems and similar.

Generally not a big deal for performance, plus, we're rarely vshader-bottlenecked...

1fd80646cb Mali driver bug workaround for driver 32+. 
See #15661

Hope this small bias won't break things.

4e5ce403b5 GPU: Process proj matrix in sw transform. 
Will need this to properly handle culling and clipping in software
transform.

Temporarily breaks display rotation handling (Vulkan/UWP.)

906a04f1fd Make sure to not leave cull distance uninitialized in other paths, if we do write to it in some path. 2021-10-26 09:56:38 +02:00

275baccc5b GLES: Support GL_APPLE_clip_distance too. 
Seems modern Apple mobile chips only support clip.

33598f2e75 GPU: Support clip and cull distances separately. 
Older GL devices, and it seems Apple devices, may not support cull.

7b00c4a572 GPU: Move Z/W equal hack to bugs from supports. 
It's really a bug (might even ideally cap the version?), and we already
have other bugs handled the same way.

1a603fedf5 Vulkan: Cull verts fully outside depth. 
Following PSP rules of -1 to 1 pre-viewport Z.  This also enables it for
GLES/OpenGL.

24011c3754 GPU: Correct depth handling for guardband. 
This culls based on pre-viewport Z and avoids culling based on the clip
range at negative Z.

a73c15babc GPU: Correct shader gen with weights as floats. 
For now, this supports the option.  We should probably just move to
everything being floats, but we already prefer software skinning.

Fixes #13903.

f3ebd6553d Turn off vertex range culling in bezier/spline calls. 
When we do lower res tess than the real PSP, we cant trust the game to not cause range culling to kick in.
