I've got a NVidia GT260M with 1GB of memory, on Ubuntu 10.4, using the NVidia 195.36.24 driver. Due to a NVidia PowerMizer bug it only runs at 275MHz rather than 550MHz. > Just having a very quick look over the code: > You still have a normal array that has 4 entries and that is set to > BIND_OVERALL which makes the shader get in the end only the first member for > every vertex it processes. > This makes me believe that the normal is no longer used? > If so, just omit the normal array completely and set the binding to OFF (I > believe it is called OFF). I think this should work. Correct, we don't use the normal. I'll make that change and re-test. One question for the release managers: Do performance improvements such as these count as bug fixes or features? Should we try to get this into the 2.6.0 release, or wait until 2.8.0? -Stuart ------------------------------------------------------------------------------ Learn Windows Azure Live!
