Best setting if you driver support GL_NV_depth_buffer_float => GL_NV_Depth = 1 & logz = 0
Otherwise => GL_NV_Depth = 0 & logz = 1
Explanation of the bug:
Dx z position ranges from 0.0f to 1.0f (FS ranges 0.0f to 1.0f)
GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)
Why it sucks:
GS small depth value will be "mapped" to -1.0f. In others all small values will be 1.0f! Terrible lost
of accuraccy.
The GL_NV_depth_buffer_float extension allow to set the near plane as -1.0f.
So
"GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)"
will become
"GL z Position ranges from -1.0f to 1.0f (FS ranges -1.0f to 1.0f)"
and therefore
"z posision [0.0f;1.0f] will map to FS [0.0f;1.0f]" as DX
Yes we just get back all precision lost previously :)
However you need hardware (intel?) and driver support (free driver?/gles?) :(

* try to use more subroutine on VS&PS, unfortunately hit a driver crash!
* Call Attach/DetachContext through GSDevice so I can unmap currently mapped buffer
* Implement glsl part of GL_ARB_bindless texture, again hit another driver crash!
* various fix of GL_ARB_buffer_storage. Basic benchmark show only improvement on 'cold' case, I guess it will improve smoothness
* try to fix GL_clear_texture, no success so far. It seem the extension is limited to basic texture (aka no depth/stencil)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5752 96395faa-99c1-11dd-bbfe-3dabce05a288
* redo most of the texture upload (PBO): colin3 benchmark: 32 fps now (vs 26 fps 2 weeks ago)
* use the cross vendor vsync extension on linux (previous wasn't supported by nvidia)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5721 96395faa-99c1-11dd-bbfe-3dabce05a288
* some preliminary work to test/benchmark bindless texture in the future (glsl was not yet updated)
Bindless texture allow to get a GPU texture pointer and then set it directly
to the shader as a basic uniform.
=> no more texture unit selection/validation
=> no more texture validation neither texture hash lookup
3rdparty: update gl header to the latest gl4.4

The idea was to replace shader program swith by pointer function calls inside
shaders. At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.
If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.
Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5715 96395faa-99c1-11dd-bbfe-3dabce05a288
* move most of gl states into a separate namespace. Extend it to depth/stencil/blend micro state
=> save 10,000 opengl call by frame for colin mcrae 3
* Only setup blend state of first drawbuffer
* Don't request anymore a debug context on dev/release build
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5713 96395faa-99c1-11dd-bbfe-3dabce05a288
* clean extension management and fix compilation of previous gl44 code.
* Use pixel buffer object to upload texture data.
=> avoid crash on AMD driver
=> a bit faster and probably got some margins for the future
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5712 96395faa-99c1-11dd-bbfe-3dabce05a288
* preliminary work for GL4.4 extensions (ARB_clear_texture & ARB_multi_bind). Disabled until I got a 4.4 driver
Note: I plan also to use ARB_buffer_storage
* compute texture gl option in the constructor (avoid a couple of swith case)
* redo texture unit management. Unit 0-2 for shaders, Unit 3 for texture operations. MultiBind will allow to bind
shader input without disturbing texture binding points.

* add a non-working hack: UserHacks_DateGL4, goal was to replace UserHacks_AlphaStencil
+ Detection of good/bad samples is based on primitive ID variable. However I'm not sure
the behavior is always the same between draw call...Anyway let's keep a copy of the current
work
* Dump integer texture into text csv
* add gl4.2 ARB_shader_image_load_store extension (needed by UserHacks_DateGL4)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5707 96395faa-99c1-11dd-bbfe-3dabce05a288
* use gles header file, disable opengl code (mainly GLX, ARB_sso, geometry shader)
* Define properly the function pointer, GLES use basic linking whereas GL must get the symbol dynamically
* cmake: properly search and set libglesv2.so
* don't use dual source blending => HW renderer work (only miss unimportant FBA)
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5701 96395faa-99c1-11dd-bbfe-3dabce05a288
* remove the possibility to compile shader from file. Some people loads older shaders...
The feature might be readded later
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5697 96395faa-99c1-11dd-bbfe-3dabce05a288
gsdx:
* move gl function loading into GSwnd. Clean the header and avoid to rely on macro.
* Always require libegl for GSdx. You still need to select the API at compilation.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5670 96395faa-99c1-11dd-bbfe-3dabce05a288
* move all remaining glx into the dedicated GLwin object
* rework a bit WGL to separate opengl context and window creation (like linux actually)
gsdx: Allow to control vsync. Not sure I used the good extension.
cmake:
* check that EGL opengl context creation
* Shut up gcc warning when force inline might not work...
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5437 96395faa-99c1-11dd-bbfe-3dabce05a288
cmake: take the opportunity to drop the support of 3rdparty compilation. Distributions have got a more recent version of zlib/soundtouch anyway.
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5376 96395faa-99c1-11dd-bbfe-3dabce05a288
* properly delete program and vertex array. Avoid a crash on plugin reload
* reset shader state. Avoid to reuse invalid data on plugin reload
gsdx:
* add an hack to unattach/attach the gl context from different thread. Help to solve some crashes. The best will be to move gpu operation out of gsreadfifo but it would need more works
* implement logz for test purpose (don't seem to help)
gsdx replay:
* use default xdg location
git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5289 96395faa-99c1-11dd-bbfe-3dabce05a288
* Fix some issue on wnd management, mix between sdl/ogl render
* create new gsdx option for ogl debug
+ debug_ogl_dump: start frame to dump when not 0
+ debug_ogl_dump_length: length of the dump
+ debug_ogl_shader: print shader debug
Note current dump option must be fixed to use linux path.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@5067 96395faa-99c1-11dd-bbfe-3dabce05a288
* fix bad setup issue for constant blend factor
* Use a read framebuffer to read back the texture (less disruptive)
* cmake separate the loader to the main plugins
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@5064 96395faa-99c1-11dd-bbfe-3dabce05a288
* add some define to enable/disable SDL so we could build gsdx without SDL
* debug: dump data based on frame count rather from draw count

* fix the backbuffer allocation. bad order of parameter
* fix remaining glsl error

* improve vertex management with a vertex array. Decorrelate vertex from strech rec and others func (later for the HW renderer)
* fix the crash on nvidia when closing the window
* clean some texture management code
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4985 96395faa-99c1-11dd-bbfe-3dabce05a288
* add a callback for GLERROR. Allow to breakpoint on GSDeviceOGL::DebugCallback (gdb is completely lost on amd driver, hope it is better on nvidia)
* Add some empty glsl convert to shutup some useless debugging error
* request an advance opengl context without pre 3.0 feature.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4983 96395faa-99c1-11dd-bbfe-3dabce05a288
* flip y-axis in merge stage
* default to xlib window managment (the dynamic switch between sdl and xlib crashi but SDL will probably dropped later)
* improve management of FBO, draw buffer
* try to fix some issue with glClearBuffer but spec is not clear.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4982 96395faa-99c1-11dd-bbfe-3dabce05a288
* implement the saving of texture (take bmp SW code)
* fix the missing "enable attribute code" and the typo in glsl. It works now !!!
* rework a little texture to pack texture into a temporay buffer when src pitch != dst pitch
* try to replace sdl with pure xlib (not yet enabled by default but it seems to work)
Note there still a minor issue, coordinate are different between DX and OGL (upper-left vs lower-left) so the image is inversed.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4981 96395faa-99c1-11dd-bbfe-3dabce05a288
* Properly allocate/delete opengl object
* Request a debug context in SDL, add some code to log opengl error
* Fix context creation. For the moment only request ogl4.1 (AMD does not support yet 4.2 and it needs libglew1.7 too...)
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4973 96395faa-99c1-11dd-bbfe-3dabce05a288
* make a rough implementation of most of the opengl device interface. Only a savestate nothing to expect yet.
* depend of libglew 1.6 (normally 1.7 but I manually defined the only missing function)
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4971 96395faa-99c1-11dd-bbfe-3dabce05a288
Current goal is to implement the SW render with pure opengl instead of SDL.
I plan to use OpenGL4.2 capability (the latest actually) => need libglew1.7 and a Dx11 capable GPU/drivers.
git-svn-id: http://pcsx2.googlecode.com/svn/branches/gsdx-ogl@4970 96395faa-99c1-11dd-bbfe-3dabce05a288
