           Summary: Homeworld 2: unusually long loading time (with
                    built-in msvcr70)

      Distribution: ---

Homeworld 2 demo loads to the main menu in no time, but starting a
single-player mission takes ~40 secs on my system. For comparison, loading the
mission in the demo takes only ~5 secs with native msvcr70.dll.
Reducing detail level doesn't affect loading times.

The demo comes bundled with it's own msvcp70,msvcr70 libraries, a workaround is
to override msvcr70 to native.

The problem is present since

msvcr70: Share the source code with msvcrt.

To reproduce the problem with the demo version:
1. install the demo, start the game with ../Bin/Release/Homeworld2.exe
-nopbuffer
(on my system the demo must be started with '-nopbuffer' option otherwise it
crashes on start).
2. the game shows a couple of logos and loads to the main menu in no time.
3. start the only available single-player mission. It takes ~40 secs on my
system to load the mission with built-in msvcr70.
