Re: [Flightgear-devel] Performance and Paris
Paris has been a heavy scenery for a long time, but in the latest GIT it seems as if it is becoming unusable. I am getting 9 or 10 FPS in multithreading mode. A FGFS version of a couple of months ago dropped my FPS over Paris on the same system to about 12-15. Performance seems to have degraded a little bit. Paris scenery is not really well done- every texture file has a alpha layer in, even if it is not necessary. Another cause is the .xml-animation. The more .xml in the scenery the more worse fps is. In my eyes it is a big issue and prevents good and detailed sceneries. Unfortunately that's no bug as I have understood... To my mind, the issue is not if the scenery is efficiently done or not, but that it is handled different by present-dat GIT and by 2.0.0 (or older GIT), and that the newer versions become slower even with graphics goodies like urban shader are switched off. I *suspect* this may be related with the performance differences I see between local weather running with 2.0.0 or GIT - both Paris and local weather having to do with a large number of (non-random) models being present in the scenery. Doesn't help much in terms of a solution though...

[Flightgear-devel] Performance and Paris
Hi Paris has been a heavy scenery for a long time, but in the latest GIT it seems as if it is becoming unusable. I am getting 9 or 10 FPS in multithreading mode. A FGFS version of a couple of months ago dropped my FPS over Paris on the same system to about 12-15. Performance seems to have degraded a little bit. In this instance I was not using local weather and the urban effect shader switched off. In other regions, my FPS rate is usually somewhere in the high thirtees to low seventees.
