xna-4.0

I have found a similar question here, but it is about playing sounds.

I am using 2048 x 2048 textures for sprite sheets and every time I call spriteBatch.Draw using a sheet for the first time in game execution, causes a considerable lag. The lag doesn't appears for the next times.

Someone has faced this problem before? What can I do to overcome this?

Update:

I inserted a code in the end of content load routine that draws EVERY Texture2D that is loaded into ContentManager before follow to the game screen. This works well. None lag occurs when different textures are rendered over the time, EXCEPT if the IsFullScreen are changed. Apparently, changing this property makes the textures loaded in the GPU gone. Is that correct?

My game uses the Content Pipeline to load the spriteSheet at runtime. The artist for the game sends me the modified spritesheet and I do a build in my machine and send him an updated project. So I'm looking for a way to generate the xnb files in his machine (this is the output of the content pipeline)… >>> More

If you used to think the XNA community was small and inactive, hopefully these XNA Notes are opening your eyes. And I honestly feel like I’m still only catching the tail end of everything that’s going on. It’s a large and active community and you can be so mired down in one part of it you miss all… >>> More
