There’s something badly broken on your blog. Scrolling continuously up and down
the page (in Firefox 3.6) is extremely slow and jerky, which I don’t usually see
unless there’s some obnoxious “active content” on the page that constantly moves
itself around when you scroll to stay visible. You don’t have anything like
that, so I’m not sure what’s causing it.________________________________

Also happens here using Firefox 3.6.13, but doesn’t happen using Konqueror.

Hello !

With Netscape / Firefox scrolling a layer over a fixed background is always jerky.

Much better. Looks like the background is part of it, though I don’t think
that’s the whole thing because (for example) Twitter pages don’t tend to be that
choppy for me. Hard to say for sure, though. I’m not a web designer.________________________________

You are right. The background was only part of it and it is not
a generall xyxy.blogspot.com problem.

hello Sam,
this is very interesting and useful at the same time! I was really
hoping that there was some more perfomant way to modify the texture
rather than SDL_UpdateTexture
just a note, you forgot NULL as second parameter of SDL_LockTexture
thanks for the happy moose tutorial

Hi,

just a question since I’m using SDL_UpdateTexture quite heavily… well I didn’t check the source code for streaming textures but is this supposed to be faster then SDL_UpdateTexture? And if yes, how?

It usually doesn’t matter, but if the driver is doing something smart like
pinning the texture memory and doing async GPU controlled DMA, you can avoid
a copy by locking the texture directly instead of keeping a separate copy of
the image data in your application.On Sat, Feb 12, 2011 at 12:23 PM, Pavel Kanzelsberger wrote:

Ok, I did a quick check in SDL_renderer_gl.c and SDL_renderer_gles.c, but texture locking and unlocking doesn’t seem to do anything except marking dirty rectangles of a texture and then updating them with SDL_UpdateTexture right before SDL_RenderCopy happens… anyway I’ll check with the OpenGL to see if there’s something like this available in some implementations, that could be used by SDL.

If you look in the latest version you’ll see that the apple extensions are
used to pin the texture memory for async DMA, on Mac OS X. It also may have
some performance benefits on Direct3D, depending on their implementation.On Sun, Feb 13, 2011 at 1:50 PM, Pavel Kanzelsberger wrote:
