Description (last modified by )
tc_CalculateVariationKey: 1.72362 s (8010x): graphics/objectmanager.cpp
TODO (for some efficiency): use the pre-calculated choices for this object,
which has already worked out what to do for props, instead of passing the
selections into BuildVariation and having it recalculate the props' choices. Release mode: 38.6697 ms
Gamesetup/config.cpp: 300ms
g_ConfigDB.Reload(CFG_SYSTEM); 216ms
LoadGlobals(); 64ms Release mode: 60ms
plain_transform: 500ms
flipping font texture files vertically. fix: convert them to e.g. DDS (possibly compressed, if that looks ok?!)
same thing for art/textures/particles/sprite
cursors also require runtime conversion. ironically enough, being DDS means they have to be converted back to TGA's BGR ordering (required by Windows for cursors) Release mode: 5ms
- CSimulation init: 5000ms
[more will be added as they are found]
Most of these turn out to be non-issues in release mode. Unfortunately the overhead in debug mode is considerable and I don't see an easy to way to alleviate that, so running in release mode as much is possible is recommended.
