Hi, Thanks very much. Related to that is the question, which is the simplest way to query PROGRAM_UNDER_NATIVE_LIMITS_ARB. Currently I have vertex and fragment programs in chunks and would like to know if it runs in hardware, ideally while initializing which is done in a static method.
When initializing the window/viewport is already available, although currently not routed to the initialization method. So something like manual activation would be needed I guess. A workaround would be to enable/disable initialization based on the graphics card string, but how would I know the limits ... I would have thought an ATI X1900 is very well able to write to result.depth.z in hardware, but it looks like it is not!
