I did some profiling of the code and found a few interessant things. Some corrections are obvious like the one in the multiplayer code, the fps is no more divided by 2 or 3 when another plane is on screen. Other things like collision detection and computation of agl can not really be optimized. I changed a few things in hitlist.cxx but this only give a very low increase of fps. The groundcache eats a lot of cpu but I think that the real way to do it is to use a real collision system like OPCODE or something like that. And I added an option to disable the recording of replay data. It takes more cpu than we can think. Changes ======= - panel.cxx : moved the computation of the instruments diffuse color outside the texturelayer code since this is constant during a frame, this is a big speedup for 2D panels ; - hitlist.cxx : changed the computation of the intersection between ray and triangle, optimized the sphere culling by using a normalized direction vector. This can give a 35% speedup on the computation of elevation in some situations ; - renderer.cxx, acmodel.cxx : call ssgDrawAndCull with plane scene graph in external or internal view, calling ssgDrawAndCull with the root scene graph was drawing other players plane a second time in multiplayer mode ; - mplayer.cxx : removed the calls to ssgFlatten and ssgStripify because it was degenerating models, causing a massive drop in frame rate ; - replay.cxx : added an option to disable the recording of the flight - fgclouds.cxx : changed the path of cloudlayer properties to match preferences.xml ; set the altitude of clouds from scenarios to a more correct value if metar is not enabled ; |
