Graphics / Huge slowdown when drawing

« on: April 19, 2010, 09:08:27 am »

An integrated chipset on a netbook with 1GB vram?

That's what I think it says - I might be misreading dxdiag.

How about just post a copy of the complete code and/or binaries so others can test it, and we can determine if its your hardware or your code?

I put it into Release to build it, and the damn thing shot up to about 40 FPS.

Still, if it's worth anything here's the binary AND the source code.

Damn, sorry for taking so long to reply. Real life has not been forgiving recently.

I'm on an Acer Aspire 1810TZ (netbook). As far as graphics go, it's got the integrated Mobile Intel 4 Chipset, with 1GB video memory.

I don't think it's my main loop, as simply commenting out the one line that draws the sprites is enough to get the FPS back up to normal. It all comes down to that one line.

Here's the render code: http://pastebin.com/xw15cqcu

I'm drawing the background for a pacman clone, using a grid of tiles. Each Tile is a basic structure that holds a pointer to a sf::Sprite. My grid at the moment is 28  by 31 - so 868 sprites drawn each frame. The problem is this absolutely murders the framerate, taking it down from about 80 FPS to about 8.

Am I going about this in the right way, or am I missing the point of sf::Sprite? Or is it something else that I should be changing in my approach? This just seems like too big a slowdown when all I'm doing is drawing the background.
