[mono-android] OpenGL/OpenTK performance :(

[Nikolai Sander]

Yes I have. This has nothing to do with the size of the triangles or blending. It is purely dependent on the number of triangles. My assumption is that there's some very slow marshaling going on for GL.BufferData().

BTW, the graphics chip of the nexus one is far superior to the one in the iPhone 3GS: http://www.taranfx.com/nexus-one-vs-iphone-3gs

My app runs faster on the *original* iPhone than on the Nexus One!

Do you (or anyone else here) actually have an OpenGL ES/OpenTK monodroid app that runs with acceptable speed on the Android?

Thanks,
Nikolai
