Screen space ambient occlusion (SSAO) On/off only. Works on creating per pixel depth, based on the pixels around them. (Very low to zero performance hit)
Does anybody have a breakdown of each shader in the shaders file, as far as what each one does?
I got this working for the most part but I'm feeling a lot of computer lag and there's some glitches on fence posts and what not, it's hard to explain. It's just not quite 'right.' I'd like to start taking shaders out and see which ones I can keep versus which are causing problems. It'd be nice to know which ones do what. Some are obvious, others far from.
/* SHADOWRES:1024 */ ; /* SHADOWHPL:80.0 */ Edit to increase shadow draw distance.
For most this setting works fine. Some performance hit. Lower number , less performance hit. (SHADOWHPL needs decibel. These need to be set the same distance apart.) General settings are: 2048, 1024, 512
(The rest have explanations)
(editable in Final.fsh)
BOKEH_DOF: Gives the effect of your eye focusing on the object you look at. Is a tiny bit glitchy, but has little to no performance hit.
GODRAYS: Sun rays. No performance hit and generally the settings are just for preferred look (Adjust in small increments to suit.Higher numbers make larger more defined godrays).
Lens (ATI) and Glare: Mostly from the sun/moon. Again, mostly for preferred look and have no performance impact.(Adjust in small increments to suit.Larger number increases the glare effect)
Cel Shading: Adds a "Borderlands" style dark outline on the edge of objects. Very little/no performance hit. Might not work on certain VC.
VINTAGE(color fade)/VIGNETTE(color tint): adjust to suit for taste. No performance hit.
CROSSPROCESS: As far as I know is a sort of high-contrast, sharping setting. Only on/off and has no performance hit.
TONEMAP: Not quite sure. On or off. No performance hit.
SCREEN_SPACE_RADIOSITY: (Currently broken for NVidia) On/Off only. Think of this as when light hits an object of color and that color carries to other objects from the reflected light. Little to no performance hit.
Tips for running the game better
Smooth lighting can really take a hit on certain VC, , so I recommend shutting that off in the in-games menu as first step.
Driver anti-aliasing: TURN OFF. Anti-aliasing Does NOT play well with Minecraft. (Other filtering by the driver as well, I think? Can someone confirm?) NVidia has per application settings in the driver settings.
HDD access can clog the game down, causing "lag/spikes" in the game. Do what you feel is necessary to limit programs from accessing too much.
Make sure you have the correct amount of RAM allocated to the game. Too much (common mistake) will cause the game to lag, as well as too little. Even at x512, the MOST you should possibly need is 2048. Most people should be set between 512-1024.
If you have a multi-core processor, select multicore support in-game. This helps some people, but other see additional lags. (Fro me it helped.)
Distance settings WILL KILL FPS. If you are having issues, try lowering to normal/tiny and find a setting that works for your setup.
UPDATE DRIVERS. This can play a MAJOR issue with temperamental games. Sound and VC drivers are the most important.
I hope this helped you!
