1432cc9431 GPU: Try a bit harder to determine safe size. 2020-05-23 00:54:22 -07:00

ea1f0a1195 Vulkan: Match safe size behavior on all backends. 
Before, we would not mark a safe size for some Vulkan clears where depth
was not cleared, deviating from other backends.  We also never detected
that on PowerVR.  This makes things more consistent.

ba566ef26a GPU: Minor lighting cleanup in software transform. 
In this case, unlitColor is already materialAmbient.

4d11256807 GPU: Avoid a texture offset change in sw transform. 
If we do it this late, it changes the shader, but that is tricky to handle
for all the backends.

48980d8786 GLES: Simplify the framebuf offset detection. 
It's clearly not been understood well as changes were made, so let's dump
a bunch of comments on it.

ad98609819 GPU: Use consistent buffered rendering state. 
The setting can be changed in Qt and Windows between frames, so let's
track the current setting in most places.  This is everywhere fbman is
easily accessible.

118e927b86 GPU: Only GL uses a flipped buffer in non-buffered, reflect that in the SW transform code. 2020-01-26 15:54:51 +01:00

c5b844cc98 GPU: Respect stencil write mask on clear. 
Actually identified this for the softgpu in #11319, but applying it for
RGBA is a problem in most renderers.  Forgot to at least apply it to
stencil.

Fixes #11901.

b955ec70c9 GPU: Correct depth clamp range in range cull. 
It was just wrong before, causing wrong culling when using a non-standard
viewport scale/center for depth.

Fixes #11701, fixes #11781.

cd6783fa0d GPU: Use provoking normal for lighting with flat. 
This might interact strangely with skinning of texture matrix mapping, but
they're not likely to be used together.

b2d60cb807 SoftGPU: Cleanup lighting code a bit. 
Avoid using Length() when Length2() is enough, simplify some things.

0c5c776bb9 GPU: Correct shade mapping with 0,0,0 light pos. 
May need to audit more normalize() usage, if it's consistent in other
places.

6600896312 GPU: Fix shade mapping in soft transform. 
Was using invalid values when lighting was off.

797327eecd GPU: Handle bad fog params as large signed vals. 
From tests, it seems they're just treated as valid exponents.

Using 65535 since that's the range of depth, can't think of a game using a
larger value for a fog parameter, probably never even this large.

dca159c47e GPU: Correct sw flat shading color on Vulkan/D3D. 
It was only correct on GLES before.  This only fixes software transform.

f9750dd137 Display: Avoid limiting FPS without a clear. 
A bit of a dirty heuristic to avoid the slowdown in #8538.

734d9c494c Fix bug in Vulkan non-buffered where clears could extend outside the frame, since Vulkan clears do not respect scissors. 2017-12-02 11:05:10 +01:00

3e011238c5 Fix minor discrepancy in shader ID calculation, I don't think this will fix anything though. Bumping shader cache version and doing minor cleanup too. 2017-11-30 22:44:39 +01:00
