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

915ff42a9a Detect clears even when outside scissor. 
Verified that scissor affects clears as well.  This allows a clear to be
detected in Katamari Damacy.

f289e8485d Vulkan: Make sure depth==stencil when clearing. 
We have to clear both at the same time.  I think it makes sense to
consider this part of the "separate alpha" flag, since alpha has to match
both color and depth.

9d8d810395 Clear detection: Don't need to check the even vertices, as the odd vertices are the ones used for color.

5cea64316a Avoid using an offset framebuffer for large tex. 
When texturing from the entire 512 height of a framebuffer, we still
should not trigger the offset framebuffer code.  This is expected to help
Danball Senki BOOST but not break Breath of Fire 3.

06e9d7680a Handle a case of 480x360 framebuffers. 
Region and scissor are 480x360, but viewport is just default (also,
throughmode is on.)  We could add more checks, but just the height being a
bit higher is already unusual, so should be relatively safe.

Fixes #7277.

eee3ac79f4 Always clamp in ToRGB[A]?(). 
Before we only clamped with SSE, better to be consistent.  This may also
be slightly faster.
