Hello guys,
I hope that you don´t allready know this trick:
1. activate file endings with a program like XP anti spy
2. Take your favorite skin and convert it with a program to .jpg
3. Copy this skin to Temp textures
4. Change the file ending into .bmp
Now the file is a .bmp but has the size of a .jpg.
A 12MB bmp has is now only 1.5MB and you have practically no reduced quality. This trick should give you a significant performance boost, but I didn´t try any benchmarks up so far.
