Gregory Hainaut	9023f5f0db	glsl: drop useless ifndef ... I often mix them with the real value... .	2015-05-08 19:28:17 +02:00
Gregory Hainaut	530e4ce776	gsdx-ogl: drop hack that rescale primitive (to avoid upscale glitch) ... Rendering is bad. It renders sprites at native resolution.	2015-05-06 19:09:13 +02:00
Gregory Hainaut	eaa0dae305	glsl: drop invariant qualifier ... Fix issue #510 and potentially it allows the compiler to better optimize the code	2015-04-27 18:52:55 +02:00
Gregory Hainaut	46ff4dc3d3	gsdx-ogl: hardware unit only support normalization of 4 bytes... ... (At least on recent AMD GPU)	2015-04-27 18:51:59 +02:00
Gregory Hainaut	301fe869c7	glsl: improve the logz handling ... This way only 0 and 1 will conflict	2015-04-26 17:51:33 +02:00
Gregory Hainaut	6a3250cad2	gsdx-ogl: fix logz management (FFXII) ... The issue is that z+1 overflow if z is UINT max log2(z) overflow if z is 0 So let's use an or 1 to avoid both overflow	2015-04-25 20:23:26 +02:00
Gregory Hainaut	36514bd95f	glsl: fog is a single byte ... Give a chance to the driver to optimize if possible	2015-04-24 21:37:37 +02:00
Gregory Hainaut	62489f42f1	gsdx-ogl: add an optimization note for later ... Only 1 byte of fog is useful	2015-04-20 07:18:09 +02:00
Gregory Hainaut	31f8c065db	gsdx-ogl: implement a new hack UserHacks_UnscaleSprite for opengl ... UserHacks_UnscaleSprite = 1 will unscale flat sprites UserHacks_UnscaleSprite = 2 will unscale all sprites (don't work well so far) The idea of the hack is to redo the interpolation of texture coordinate based on the non-upscaled pixel position. It avoids various glitches but sprites aren't upscaled anymore (so no more anti-aliasing, potentially a coefficient can be added).	2015-04-20 07:18:08 +02:00
Gregory Hainaut	16e6d0d305	glsl: move shader into a separate directory ... Only keep glsl_source.h for clarity	2015-04-19 18:49:02 +02:00
