I recently tried to port my application to my laptop and was surprised that
the installed geforce 7 go did not support rendering to any
two component rendertarget (driver was up to date).
In order to reduce these future surprises to a minimum,
I suggest that we start to build a database of supported/unsupported
renderformats for all chips that are of interest.
The formats I most care about are GL_RGBA16F/32F and
GL_LUMINANCE_ALPHA_16F/32F, feel free to propose your favourites.
Things like hw-accelerated mipmap generation would be nice
to know too, but I fear that this depends more on the
driver-version then the actual chip.
Until a better place is found (OpenGL wiki?), we can use this thread as data-dump.
Well, that doesn’t sound right. According to the spec:
The following base internal formats from table 3.15 are
“color-renderable”: RGB, RGBA, FLOAT_R_NV, FLOAT_RG_NV,
FLOAT_RGB_NV, and FLOAT_RGBA_NV. The sized internal formats
from table 3.16 that have a color-renderable base internal
format are also color-renderable. No other formats, including
compressed internal formats, are color-renderable.
so you can consider color-renderable LA*F textures a feature on GF8xxx hardware
