--- Comment #2 from Piotr Caban piotr.caban@gmail.com 2013-11-22 05:51:37 CST --- On windows _getmaxstdio returns 2048 in msvcrt.dll and 512 in msvcr90.dll. The MSVCRT_max_streams value should be changed. Changing MSVCRT_fstream size doesn't make sense.
I would like to take a look on the demo before changing MSVCRT_max_streams. Most probably the game is leaking file handles due to some other bug.
