Hello,
porting a game from android/ios to winRT and win phone 8.
works perfect on winRT.
however on win phone 8 on the nokia 920 we see a lot of slow down dealing with CreateTexture2D. mainly since we have to convert a lot of palleted textures to full RGBA images. could anyone recommend the best format to use to get the most performance? we already have 80% of our textures in DXT3 and DXT1 format (BC1 and BC2 in directx) however we simply have some images which are 16 color palleted images which we for one reason or another can not convert to dxt3 or dxt1

Thank you very much.
