Will it increase the fps in my engine if I load TGA or RAW images rather than bitmaps? If so, which is the most efficient? Open mouth, insert foot

Nope, shouldn''t be any difference.

Then what is the point of loading a TGA image with 60 lines of code when you can load a bitmap with 10??

There are many reasons but one of them is that the TARGA format has support for alpha informations. Also, it comes in a variety of bit depth (8, 16, 24, 32 and probably exotic stuff like 2 and 4), can be compressed and is supported by a wide variety of image editing programs, 3d renderers, etc on multiple OSes.

I never used RAW images so I don''t know anything about that. However, the file format shouldn''t make any difference in your FPS at all.

BTW never assume than I''m correct. You never know.

by bitmap i takeit u mean a *.bmp file.
there shouldnt be much difference in loading speed between the two (uncompressed targa''s + *bmp''s). you''ll notice a loading slowdown using a compressed format though eg jpg,png due to the uncompressing.
i dont recommend using raw files (no header)

The image format you use shouldn''t make too much different. However, Targa images allow you to use the Alpha channel, which allows you to create some pretty neat effects.
