I do not doubt that you can make FG run out of memory on a 32 bit system (you can also do it on a 64 bit system if you try really hard). My point is more that memory issues should be dealt with by eliminating the root cause, i.e. by switching off random buildings and trees on a low memory system and by not using hires textures, not by reducing visibility to low values. Compared to the memory footprint coming from high-detail aircraft and random buildings, the effect of 10 km vs 20 km visibility on memory is negligible. We have aircraft in the repository which fill more than 300 MB of GPU memory - loading terrain vertices worth 20 km is a very small fraction of that, even in hires scenery. Even in custom Italy with 50 km visibility, I had about half a million of terrain vertices in the scene, that's 1.5 million or so numbers. That's the order of magnitude of a good-sized texture sheet - 1024x1024 has about a million numbers - with a lower precision, but with added mipmapping,... * Thorsten ------------------------------------------------------------------------------ Everyone hates slow websites.
