[SOLVED]Rotate Picture Lag

[MarioSuperStar]

So, I have this picture of a resolution of 800x800. I made it appear in RPG Maker
with no lag. But when I make it rotate, the FPS drops down to 20FPS. Is this normal?
How can it be solved?

Rotation is a very time-consuming process, and even more with huge pictures like yours. Significant slowdown is likely to occur and can hardly be prevented. The only solution I can think of is to perform a rotation only once in X frames. For example, instead of performing a 10 degrees rotation every frame, perform a 40 degrees rotation and then wait 4 frames. The rotation will appear less smooth but the slowdown should decrease.

The other option would be to save rotated versions of the image, and cache them individually.

Not sure if your application would support this. If you want smooth rotation of a large image, you might be out of luck.

I think I moght use your option, tested it, and, seems to not mess with the FPS.Thanks, both of you!
