Gregory Hainaut 1e3c46a6bb gsdx ogl: purge debug message in destructor
Allow to see latest error and avoid noise in Valgrind log

Gregory Hainaut 85fb55a0e1 gsdx ogl: memory management take 3
Add a factor 2 on the VRAM to get the quantity of available memory for the textures.
The driver is allowed to put some textures in RAM. Of course it is bad for performance
but it won't crash.

Due to the 4GB by process limit, I keep a (reasonable) maximum of 3.8GB.

In order to avoid a crash when memory is too low an exception will be risen
with no guarantee on rendering and big performance impact. In this situation
you ought to reduce upscaling/disable large framebuffer.

Gregory Hainaut a37cd40ce3 gsdx ogl: only print an error when VRAM is low
Until a better solution is found or people buy better GPU :)

Gregory Hainaut a2086ed458 gsdx profiler: drop latest frame time
Value is out of the chart. I'm not even sure it is a real frame so let's just remove it.

Gregory Hainaut 82d83ca579 gsdx: dull driver
Hopefully futur low-end GPU will get 4GB of VRAM

Gregory Hainaut 3f03f7333c gsdx: improve builtin profiler
* Does the first vsync (start counter) after the sleep
* Dump data after the rendering, avoid to count extra destructor,sleep time
* Dump data into a basic csv file (if people want nice graph)

Gregory Hainaut eefe3e8d4f gsdx ogl: reserve 200MB of the VRAM for various gl buffers (IBO/VBO/PBO/UBO) 2016-07-08 09:43:47 +02:00
Gregory Hainaut df4645a84a gsdx ogl: Don't use NV extension on AMD
potentially the NV extension is wrongly used but can't test it with the free driver

Gregory Hainaut d8050634f6 gsdx ogl: plug GL_NVX_gpu_memory_info and GL_ATI_meminfo
to query available memory on the GPU

Requirement
* dedicated GPU (ofc!)
* proprietary driver. Free driver supports r600, radeonsi

Gregory Hainaut a065a1d918 gsdx ogl: don't use GL_ARB_clear_texture for the depth buffer
It creates some slowdowns for unknown reason. My best hypothesis is
that stencil will be cleared too which is slow.

Let's keep the code for the future when stencil will be dropped.

Fix #1420

Gregory Hainaut d7c1faf563 gsdx ogl: add GPU timers to measure time between 2 vsync
So far only basic stuff (min/mean/max frame rendering time)
2016-06-26 15:34:36 +02:00
Gregory Hainaut 79587215bb gsdx ogl: add the option force_texture_clear for test purpose
Might be completely useless.

1 => always clear framebuffers and textures to black (aka 0)
2 => always clear framebuffers and textures to red

Gregory Hainaut 3234c8241b gsdx ogl: massively extend glsl self test
* Support Mesa Nouveau IR (free driver for Nvidia's GPU)
  => Print intermediate representation + final shader
  => Dump GPR usage
* Move dumped shader in /tmp/GSdx_Shader/<sub_dir>
  =>  Avoid the landing of 3 thousands of files in $PWD ^^
* Use function instead of macro

Gregory Hainaut 1c8de02c8d gsdx ogl: trace shader permutation
Too much permutation is bad for driver performances

Gregory Hainaut 5d49a6b685 gsdx ogl: replace 4 VS shader variation by an AND mask
Perf will be roughly the same. However there is a single VS for all
the HW emulation.

Gregory Hainaut 959abe64f8 gsdx ogl: implement wildhack on the CPU
Speed impact is likely small and the plan is only to keep a single Vertex Shader

Gregory Hainaut f7ddd488e1 gsdx ogl: Extend uniform buffer with channel parameter
Instead to use the standard ps ubo which is used every draw call.
I reused a barely used buffer to reduce the extra cost of the upload

Gregory Hainaut 6f19d928f6 gsdx ogl: use the new uniform cache upload method 2016-05-29 10:13:43 +02:00
Gregory Hainaut 179681ef18 gsdx ogl: enable AMD driver blending workaround only on latest legacy driver
Legacy GPU:
Older driver will be broken.

Still supported GPU:
Please upgrade to the latest AMD driver 16.5.2 or 16.5.3 (and prey that future driver will still work)
2016-05-28 18:43:55 +02:00

Gregory Hainaut 1522cba5b0 gsdx ogl: performance note of texture clear vs framebuffer clear
In case of render target. FB clear is better

Gregory Hainaut 3ab12cef2f gsdx ogl: accelerate special case of accurate date.
Game often uses date to allow a single pixel pass. If this
use case is detected, stencil buffer will be cleared after first pixels
that pass both depth&stencil test.

It seems to reduce the load on the GPU.

Note: with the help of texture barriere, maybe we could implement the algo
with a single pass.

Gregory Hainaut 5b061e062c gsdx ogl: replace ClearRenderTarget_i by glClearTexSubImage
Avoid state change, avoid potential texture buffer reallocation

Note: require GL_ARB_clear_texture
2016-05-15 15:55:31 +02:00
Gregory Hainaut c054b097e9 gsdx ogl: fix wrong depth clear
If a color buffer is still attached and is smaller than depth buffer,
the latter won't be fully cleared.

As a faster alternative, use GL4.4 clear texture function. Avoid to fiddle with
framebuffer and pixel tests.

Gregory Hainaut cd9ee3c468 gsdx ogl: emulate GL_ARB_draw_buffers_blend and GL_ARB_viewport_array

set all buffers

Gregory Hainaut d41613c46a gsdx ogl: add a Tales of Abyss HLE shader
Again fast and efficient but it relies on CRC

v2: forget to update the precompiled shader...

Gregory Hainaut e890ce989c gsdx: throw oom exception + error
Texture can't be NULL anymore, so we can remove a couples of check
2016-05-05 18:53:51 +02:00
Gregory Hainaut d58b71688b gsdx debug: auto GL_POP
Nicer and exception safe

V2: miss definition of vs/ps

Gregory Hainaut 5948c2d8cd gsdx AMD: broken for broken
Until AMD release the driver with a fix, I can't use 2nd blending source with SSO.

So let's use the first source. Blending/Alpha will be wrong. But it is likely better
than an uninitialized alpha value.

Gregory Hainaut 14e1ed06df glsl: add an HLE shader for Urban Chaos
Pro:
* Replace 140 draw calls into a single one
* No complex texture conversion/lookup
* smaller solution than a generic solution

Gregory Hainaut fda511a949 gsdx glsl: extend hw shader to sample depth texture
Will use integral coordinate to avoid any rescaling.

Bilinear interpolation isn't supported. I don't think it is allowed to
filter a depth texture anyway.
