Flyinghead 3a7a08f3fb Do not clear the framebuffer before rendering. Fix scissoring coords. 
The framebuffer is cleared by the background plane using global clipping
coordinates. This allows multiple rendering to different locations on
the framebuffer.
Fixes flashing menus in Vanishing Point, loading screens in Test Drive
Le Mans and Vigilante 8.
Better rear view mirror in Metropolis Street Racer.

Flyinghead cc8569fcf8 Fix 8888 high-quality textures on GLES/arm 
GLES doesn't support uint 8888 so bytes must be swapped on little endian
architecture.

Flyinghead 0284d635d2 Upscale rendered-to textures 
Increase the size of RTT textures by a given integer factor. Defaults to
1.
This gives much better quality textures, particularly visible when used
fullscreen for transition or pause screens.

Flyinghead bb2d860902 Use red channel for fog table in GL but continue using alpha channel in 
GLES. Alpha channel is supported only in GL compat mode, not core.

Flyinghead 87f8c5194f Better fix for texture cache key needing StrideSel 
StrideSel and ScanOrder are no longer part of the texture cache key
since that breaks RTT texture matching. But they are updated at lookup
time so they will be used if the tex is updated later.
Fixes RTT-based xfade screens in Skies of Arcadia.

Flyinghead 889f722e73 Fix PAL4 textures 2018-07-09 19:20:33 +02:00
Flyinghead 18b2d8273f Improve paletted and YUV texture quality. 
Paletted textures using a 32-bit palette and YUV textures are now
converted to 8888 format, which results in a lossless conversion.
Fixes background texture quality in Alone in the Dark.

Flyinghead a89ff1e432 Ignore depth func for autosort TR polys. 
This was a remain of the previous Always depth hack.
 2018-07-07 08:46:29 +02:00
Flyinghead e067534f26 When sorting translucent triangle, keep the third vertex in place. 
In flat shading mode, the third vertex of a triangle defines its color
so we must maintain its index.
Fixes the remaining color polygons seen in Evolution - The World of
Sacred Device.

Flyinghead 3ddcc272bf Fix autosort/presort mode selection. Per render pass sort mode. 
The previous algorithm to determine the sort mode for TR polys was
faulty. And the sort mode can vary between passes for multipass
rendering. This also removes the need for the hack to support Always
depth mode with autosorted TR polys. Should fix the Resident Evil 3 menu
problem.

Flyinghead 7ecd384612 StrideSel is now part of the texture cache and must be set by RTT 2018-06-29 19:03:43 +02:00
Flyinghead f18aa63a67 Add stride and scan order to texture cache key as they are used to update the texture

Flyinghead a94f01ee78 Force autosort TR triangles using depth func Always to be drawn on top of others 
When autosorting triangles, ignore the depth of triangles using the depth func Always and force
them to be on top. Seems to help Psyvariar 2.

Flyinghead 6871061ca0 Modifier Volumes: summing up with triangles is faster than using a quad. 2018-06-26 15:38:55 +02:00
Flyinghead 7c93727b5e Improve modifier volume parsing and drawing logic. 
Parse modifier volumes similarily to other polys (first, count, params).
Draw all triangles in one shot and use quad to sum up instead of
redrawing entire strip. Use OR operation for open volumes/quads
(Soulcalibur).

Flyinghead 846d02d9d2 Optimize RTT to VRAM. Add US version of THPS2 to per-game settings. 2018-06-25 16:55:22 +02:00
Flyinghead 3256e02813 Workaround for Virtua Tennis ball color problem. 
There's a texture corruption of the tennis ball and other textures,
notably the players' bags in the first intro sequence. The corruption is
due to render to texture squashing existing textures. Not sure what's
going on but this avoids the texture corruption. The original problem
remains.

hardcoded value.

Flyinghead 9098fd5a22 Autosort poly: Write to the depth buffer in a second pass, and only if 
multipass rendering.
 2018-05-20 21:41:31 +02:00
Flyinghead 2d904372a9 Multipass issues: depth mask must be enabled for autosorted tr poly. 
Depth buffer must NOT be cleared b/w passes, same for stencil I guess.
