To clear a (W, H) RT/Depth, GS can only send a (W , H/2) primitive with
a Z (or RT) pointer in the middle of the buffer
Top-half will be cleared by the color (or the depth).
Bottom-half will be cleared by the depth (or the color).
Code isn't enabled yet but it was tested with success on GoW2.
UserHacks_round_sprite_offset = 1 <= enable correction of flat sprites
UserHacks_round_sprite_offset = 2 <= enable correction of all sprites (better on a couple of dump but not sure of the consequence)
I completely redo the algorithm. This time I do the projection and
interpolation of the 2 extrem vertex. This way I can compute the min/max
valid texture coordinate.
It gives stronger guarantee that texture sampling will be done inside the texture.
However it might have a performance impact, likely reasonable because it
is limited to sprite vertex.
A big thanks you to all people that provide me GS dump and test reports.
It is replacement of the previous hack (UserHacks_stretch_sprite). Don't enable both in the same time!
The idea of the hack is to move the sprite to the pixel boundary. It
avoids most of rounding issue. It also rescales verticaly the sprite (avoid horizontal line on ace combat).
I don't like this rescaling maybe we can limit it to only 1 pixels.
On my limited testcase, results are much better with any upscaling factor.
I still have a bad line in Kingdom heart. If you have issue with others
game please provide us a GS dump.
2x upscaling is pixel perfects. Bigger upscaling is better but not yet perfect
Feedbacks are welcomes (note it doesn't solve all upscaling issue, only wrong texture sampling)
For the history:
If you have a texture of [0;16[ texels and draws a primitive [0;16[
The formulae to sample last pixels of texture is
0.5 + (16*s-1)/(16*s) * 16
Native (s==1): 15.5 (good)
2x (s==2): 16 (bad, outside of the texture)
4x (s==4): 16.25 (bad, really outside of the texure))
HTB123 on our forums came up with a hack that removes the broken main character shadow in hardware rendering
in SMT Nocturne.
This should work for all GSdx recognized versions / regions of the game (tested EU and NTSC-U).

- 0: no multi-threading
- 1: gif packet processing and texture uploads run parallel with rendering, the slowest decides the fps, dual-cores can still suffer by the spin loops, I'll check that when I compile pcsx2 on my notebook
- 2: two rendering threads, on a decent cpu packet processing is going to be slower now, this is probably going to increase fps the most on quads
- 3: small fps increase
- 4+: even smaller.
If you have a quad cpu with HT, 6 is the max, 1 + 1 is needed for pcsx2 and gsdx's basic tasks.
Also hacked palette writes to not force a read-back in hw mode (added in previous rev), it hit render targets in a surprising large number of games.

Important: this is not a fix of the cause of the crashes, it just bypasses cases of sure crash. Once that spot is bypassed, things can go wrong elsewhere. Generally, however, things just continue normally. E.g. GT4 (camera changes), Tourist Trophy (camera changes), MGS3 (codec screen when CRC hacks are disabled) and probably more - now don't crash anymore, even at high resolution (but might still get some slowdowns).

Summary of changes...
Fixed menus and HUD for Spyro: A New Beginning and Spyro: the Eternal Night.
Fixed missing dialogs and reduced the VRam usage a bit for Tales of Legendia ("8-bit textures" help a bit more with Vram/speed). Should be playable now in hardware mode. Thanks to rama for figuring it could be hackfixed this way and the initial patch :)
Half-screen fixes for Ty the Tasmanian Tiger 2, X-men Origins: Wolverine, Call of Duty: World at War - Final Fronts.
Modified the Star Wars: Force Unleashed hackfix a bit, shouldn't have the see-thru objects anymore.
Also modified the Metal Gear Solid 3 and Gran Turismo 4 hackfixes as they needed different skip values for each region (PAL/NTSC). Thanx to avih for the region code... and the free C/C++ lessons :P
The hackfix for Sly 3 was still showing stripes for 3-D and two-player modes, fixed for NTSC version now and hopefully works for PAL one too.
Couple GameDB updates after the gif rewrite.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4833 96395faa-99c1-11dd-bbfe-3dabce05a288
Adjusted the SW Battlefront hackfix for the PAL versions (NTSC-U and PAL versions have the same CRC but use slighty different buffer/texture addresses...)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4787 96395faa-99c1-11dd-bbfe-3dabce05a288
The Lord of the Rings: the Third Age (Removing fat stripes on screen).
Digimon Rumble Arena 2 (Half screen issue).
Star Wars - The Force Unleashed (Hiding HUD and 3d issues. Not perfect and NTSC-U only, not sure if it works with PAL).
Star Wars Battlefront 1/2 (Huge VRAM usage issue. NTSC-U only, not sure if it works with others).
Black Hawk Down - Team Sabre (Half screen issue and removes the night vision filter which was broken and using a lot of VRAM).
Minimal changes to other CRC hackfixes and GameDB.

GameDB: Onimusha 4: Dawn of Dreams playable again with a patch. Minor other updates.

New define "NO_CRC_HACKS", for testing how games work without hacks easily.
Gets enabled together with the no cache define but can be toggled individually as well.
Also I've been told to mention that these changes are not directly benefiting the end user.
Gamers: This doesn't fix your DragonBall, okay? :p

- Allow filtering setting for native resolution hardware rendering, as it's not tied to the resolution.
- Add ST / UV coordinate tweaking defines to more easily debug small rendering glitches.
- Add a define to bypass the hardware renderer texture cache. With this enabled, speed drops to slower than software rendering.
It fixes nearly all hardware rendering issues though and can be used to see how games *would* look if we had a new cache ;)
Thanks for the help, sudonim :)

Also a few changes for Tekken 5, "City at sunset" stage, hopefully there's nothing else wrong with this game anymore.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@4585 96395faa-99c1-11dd-bbfe-3dabce05a288
- GSWnd is not implemented, no config dialogs either
- no output, just the null device
- threading classes were not tested (my first experience with pthread)

GSDx: Reset device on save state load.
GSDx: Made GSRenderer::ResetDevice() actually do the main function in its name and implemented InvalidateTextureCache(). If anything breaks, it's because of this change.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3067 96395faa-99c1-11dd-bbfe-3dabce05a288
- Finally made some user hacks available in the configuration dialog.
There are no warnings yet, and I don't like the placement either, but that'll have to wait.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2606 96395faa-99c1-11dd-bbfe-3dabce05a288
Gave up on the smart m_width / m_height adjustments for now. This just won't work the way I imagined it :/
Using a "common" size of 640*512 instead. This means some odd games might use a wrong output surface again (they always did this on the normal upscaler).
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2190 96395faa-99c1-11dd-bbfe-3dabce05a288
- Reduced the overhead of the new scaler. Instead of just using 1024*1024 blindly, it tries to adapt to games native resolutions.
- Yet another change to IncAge(), since it seems to be (mis)used to do texture invalidation. (Fixes Disgaea 2 when booting through the BIOS)
- Added some comments
Note:
Before working on the texture cache GetDisplayRect(),GetFrameRect() and GetDeviceSize() really need fixing. It's useless to try and find surfaces when not knowing the real size of things.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2174 96395faa-99c1-11dd-bbfe-3dabce05a288
- Bring back IncAge() for textures to avoid excessive memory usage by some games.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2140 96395faa-99c1-11dd-bbfe-3dabce05a288
- Fixed many flickering scene change transitions (FF12, Gust games, etc).
- Found more info on how games do some special effects. Preliminary code included, but disabled.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2101 96395faa-99c1-11dd-bbfe-3dabce05a288
- More work on the configuration, preparing for some reorganization.
- 8 Bit textures default to off again, since there are issue reports (mainly from ATI users).
- Add a gamefix that allows users to set an amount of "bad" frames to be skipped.
Add gamefix_skipdraw = x to the GSdx.ini to enable. (More work on this soon)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2085 96395faa-99c1-11dd-bbfe-3dabce05a288
Added a somewhat more accurate upscale option via GSdx.ini. Not tested much! :p
