Big images - performance problems

Troubleshooting graphics
1

hello,

Im about to write a board game in jme. I have a big image something like 5MB png  2024 x 1437 which is a scanned board. I create the texutre and i put it on the quad. Everything is fine except one thing - it takes a longer while to load it,  its not acceptable. Is there a way to load it faster?

thanks

Break it up into multiple smaller images?



No idea if that would improve or worsen performance but it's about the only suggestion I can think of.

Oh and if your image isn't a power of two it'll get stretched when loaded, which probably eats up a little bit of time not to mention making your texture look bad.

Yes, don't use 'normal' image formats but the texture target format (in the correct size, as Gentleman Hal said) to avoid conversions.

And a lot of time goes into mipmap generation, don't use that or better yet use the dds format with mipmaps pre-generated. Then your image should load in a breeze.

Why dont you just reduce the size of everything and position the camera closer?



Problem solved (again).  XD

The size of what? of my texutre image? There is quite a lot of text on it so i can't just reduce the size because it won't be redable any more.

I meant EVERYTHING! Ok, texture text is a good reason not to reduce it. Why not blend the text out in Photoshop and create a number of carefully positioned Text nodes.

Firstly because the problem is resolved already, secondly  because i would have to create about 50 carefully positioned text nodes :D.

Ok, but solution 2 is there for anyone else
