Haha... Certified myself to Apprentice. Lol.
This site looks like a cool concept, and I hope to use the developer diary on here somewhat like a .PLAN file, for those of you who are interested in more development information than the CVS log can give you and want to, in effect, "peer over my shoulder" as I work.
That being said, here's my first entry to that effect. I read a great article on FlipCode about the necessity of bringing down game load times, and I've been endeavouring to do just that over the last several weeks. It's taken me through several paths, namely, the removal of classic MDL model support, as MD2s load more quickly and don't require us to triangulate at runtime. This has also allowed me to remove the NVTriStrip library which was adding some significant code bloat.
In addition, much of the Quake loading code parsed all structures byte-for-byte doing endian swapping. Since everything we've done so far is non-portable anyway, I converted everything from endian swapping parsing to straight memcpy() out of the files. This is a most notable change in the BSP loading architecture. To that end, I also implemented MMX and SSE SIMD-enhanced memcpy() functions out of the xine codebase (http://xine.sourceforge.net). Thanks to them for making their project GPL as well!
In that manner, I've already shaved off about three seconds from inital game loadtime (as measured with a commandline containing +map e1m1). Changelevel loadtime is still about the same length as when I started, which may indicate there's significant overhead in deleteing all the data structures from one level and reallocating them for the next level. I'm not saying I'll go to static storage for all those objects, but it might be a consideration for further work. I'll commit all this stuff to CVS once I'm sure all this stuff isn't going to explode.
And one more note - the MMX/SSE code now requires that you have Visual Studio 6 Professional or Enterprise, with both Service Pack 5 and the Processor Pack installed, or the SSE will choke about the prefetchnta instruction being invalid. Don't say I didn't warn you.
