optimization - How can I speed up my Java game's FPS? -

-

i making java game, , game lags lot when paint out graphics. way painting out graphics make bufferedimage, graphics2d it, whole bunch of:

g2d.drawimage(loadedimages.getimage(),x,y,null);

after print of images bufferedimage, paint bufferedimage screen.

there lot of images paint bufferedimage. there better way speed painting time? not know graphics , graphic cards. should use graphics card? should paint directly screen? should use entirely different drawimage()?

the performance should if you're drawing reasonable amount of images.

make sure you're not creating new bufferedimages every time draw screen. example, might have resources singleton in manage of images load , unload each image once.

if want more performance, you'll want use opengl. see lwjgl, libgdx, or jogl. may want consider 2d graphics libraries slick.
