Additionally, you can pack a bunch of different images onto a single texture (which is actually the most efficient way of doing certain things) and render different sections of the texture at will.

One of the things you don't seem to realize is that images don't have to be PoT (power of two), allocated texture memory is placed onto PoT blocks. What you're worrying about is not an issue. You can use textures any way you like - sprite atlases, tiles, etc etc. Stop worrying about textures and scaling, textures are just how image data is stored. It doesn't make sense! I hope you guys understood my fears and can show me some solutions. So my questions are: Am I right? Is texture wrong in this case, and it's better to just draw in the screen, like graphics.drawImage()? Why? And if it is better just to draw, is there some way to do it with LWJGL? If not, then I can conclude that LWJGL is not really suitable for my needs? And if I am completly wrong, then how should I proced to solve the wire sprites problem? I don't want to resize then to 4x8 just to have then resized back to 4圆 when the program runs.

The problem is that it doens't make sense to use textures in my game, because since it's 2D (and top-view), there is no rescaling - ever. And the image is too small for rescale, it would look ridiculous. The problem with LWJGL is that it is based on textures, and therefore every image should be power-of-two sized. The wire sprite was 6x4, and I just draw it using Graphics, and it worked perfectly. The problem was when I started to convert another feature, that would be like a wire drawn over the tiles. And my game has a tile-based map, and then I started doing the part that would read the map from the file and draw, and it worked fine, because the tiles are 16x16 pixels. But on a early stage I decided to migrate to LWJGL, because everbody was saying it was cool and better, etc. I started developing this fairly complex, commercial indie game, that is in 2D, with regular java classes (AWT, Swing, Graphics, etc). Hello everbody! Maybe my question is really stupid, but let me show some background.
