I'm having something which *may* be similar. To check if it's the same issue, please set the following environment variable, and run fgfs again: OSG_GL_ERROR_CHECKING=ONCE_PER_ATTRIBUTE And post the actual attribute number that is logged) > > This may be dependent on graphics cards-- I have an ATI-based HD 3850 > from a few years ago, so maybe many folks don't see this warning.

That sounds like a different issue to mine, but we shall see. In general, the Ati drivers seem much stricter in checking state that the nVidia drivers accept and tolerate. > > Working under FG 2.4 with various -set.xml files, after a lengthy > process of elimination and replacement I finally found what is > triggering the warnings: the 'radar' instrumentation module.

That's strange indeed - as you say, the radar should not be used if not included, since it can eat a few FPS to generate the texture. Its state-sets are pretty simple, so I will be very interested to see what error is reported once you set the environment variables above.
