Now, a note about the actual issue. Destination alpha tests can be used on the GS as one of the workarounds for a lack of stencils. If you use a destination alpha test and leave alpha writing on, the GS will only write each pixel until you write an alpha value which would fail the test. This works to a point in gsdx without further hacking, but that point is when within a single batch of primitives the same pixels are written multiple times and the destination alpha test is expected to update. I did experimentally make a tight loop updating the stencil with a draw then drawing for one primitive at a time, but it was prohibitively slow (over 80% fps loss, you really don't want to know).
Destination alpha testing cannot be directly implemented in D3D9 or D3D10, but (probably) can in D3D11 (with a speed hit for sure, but I doubt it'll be 80%). I'll be getting a new graphics card and looking into that.
And before some idiot says it, the answer is no. OpenGL does not help.

- Added "Aggressive-CRC" checkbox at the HW hacks section of the config dialog.
- The following hacks are now activated only in aggressive mode:
- God of War 2: disable water effect/lines, disable global haze.
- FFX, FFX2, SSX3 (the full crc hack from r5214).
- Shadow of the Colossus: disable (over)bloom.
- Reverted the Valkyrie Profile 2 hack to pre- r5214.
- Some CRC fixes by comments on r5214.
- Regression fix of dynamic crc hack (INITIAL_MODE = 0 didn't compile)

Mouse over descriptions for the hacks. Thanks to KrossX again, these are great :)

Adding KrossX's Wild Arms text alignment hack to the new dialog box. This hack is actually very interesting for a number of games. It should work well in cases where game designers adjusted everything pixel perfect for the GS, that usually breaks with upscaling.
It should be generalized and renamed later.

Team effort of KrossX and myself:
Finally adding that special game fixes / hack dialog I talked about for a while.
Committing this in several steps to clean up any issues easier.

Committing a hack KrossX prepared (thanks) ;)
It can be used to fix bad character sprites in Gust games.

- 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.

Also added Valkyria Profile 2 Italy to the gamedb and GSdx crc list. By Leucos.
Thanks guys :)

Avih renovated the configuration dialog a bit. It makes lots more sense now, thanks :)

Another round of configuration dialog renovations.
Fixes the leftover "Skipdraw" text when hacks are disabled.
Group the options a bit nicer. Group hardware Anti Aliasing with hacks.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@3693 96395faa-99c1-11dd-bbfe-3dabce05a288
- Fixed the resource issue I had, so the new options are now also available in the old config dialog.
- Added some code that hides the hack options completely when they're disabled. By Bositman :p
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2619 96395faa-99c1-11dd-bbfe-3dabce05a288
- Added multi sample anti aliasing options to the gui. Remember those aren't tested much, and we have reports of memory leaking with it enabled. Those could be outdated by now though.
- Removed the "enable output merger blur effect option", since I can't imagine anyone wanting to enable it anyway. :p
- Cropped one more pixel on the final output image, should fix some issues with msaa enabled.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@2607 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.

PCSX2: Added an optional PS2EsetEmuVersion callback for plugins, so that plugins (like GSdx) can alter behavior based on the version of emulator calling them.

- 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)

- Worked on the configuration dialog, bringing in the scaler option
- Changed the DeviceSize code to use Jake's kinda better method. Fixes some odd resolution games :)

- trying the dx10.1-only "gather" shader instruction for palletized lookups ("8-bit texture" mode), saves 4 instructions which isn't much but still... (not tested, don't have ati)
- may fix the intel gma "no output" bug (don't have gma either :P)
- and the usual small code optimizations
