I changed the rendering method for the main persistant GUI elements like buildmenu, order menu, info, playerlist widgets, top bar, ecostats, idle buiders, unit groups and chat. The render their changes to texture instead of GL display lists. Performance increase is for both the cpu + gpu! Bonus: Uniit icon textures now are more detailed! We can simply make the texturesize for those widgets twice as big, so mipmaps are always good! (this has been live since 3 weeks ago)
