Normal Blender: Enable this if you have problems with transparency problems in games.

Normal Combiner: Enables the normal color combiner. Use this if you you have texture color issues, transparency problems or issues with monochrome textures.

Accurate Texture Mapping: This option enables more accurate texture mapping. This is useful if you have thin line problems in some games.

Faster Texture Loading: This option speeds up texture loading, through a faster CRC (cyclic redundancy check) calculation and checking algorithm.

 

Framebuffer Emulation

Note: Framebuffer drawing is currently incomplete in the OpenGL renderer. Also, hardware framebuffer emulation is incomplete in the development branch plugin, which is why these options are unusable in it.

N64 Frame Buffer Emulation: This option controls framebuffer emulation, which is often used by games for special effects. The options are:

Rendering to Texture Emulation: This option controls how render-to-texture operations are performed by the plugin. Render-to-texture is a component of framebuffer emulation. The options are:

Framebuffer Write Back: This option controls the frequency in which frames from the framebuffer are written.

In N64 Native Resolution: This option sets the framebuffer resolution to the same as used on the original N64.This option is very useful if you want to save precious VRAM , especially on 32MB cards and lower.

Try to save VRAM: This option makes the framebuffer algorithm more conservative in how it manages textures in its texture cache, thus saving RAM.

Automattically Write Back Overlapped Texture: This option will automatically write back textures in the framebuffer if they are covered partially by new framebuffer textures.

Double the Resolution for Small Render-to-texture: This option will double the resolution used by small render-to-texture buffers, like dynamic shadows.
