Description

I already had made a similar report about it, but Squall-Leonhart from the
emuforums.com said that the OGL in DolphinWx uses version 1.2. So a
Graphic card with 1.5 or 2.0 support from the series GeForce FX should be
able to emulate fine. To get the plugin work fine it need to emulate NV40
via RivaTuner. This way get a huge drop perfomance because the processor
need to emulate the NV40 extensions.

I know i won't get really great FPS with this GPU, but it could run with OGL
natively instead of emulating instructions of another card.

what is the issue though?
we se frame buffer objects and non power of 2 textures extensions from opengl 2.
We also use shaders and other advance opengl things. And yes software fallbacks for
them will be slow if working at all.

Well without emulating NV40, the plugin starts but don't show the textures and 3D
Objets, only a "background" color of the menus. So if the plugin uses some
extensions of version 2.0 then I think there is no way to get it run natively on a
NV30

we don't use NV40 or NV30 we use opengl...
some of the opengl extensions were NV extensions that got approved.
I think you confuze emulated with software fallback and natively with hw accelerated.
anyhow, yes the chance of making it work with old cards is close to none.
