Array size?

I just tried to set an array size to display width/height and fps bottomed out. So Im wondering what the maximum safe size is that I can use?

Anything which will reasonably fit in memory. There is no predefined limit.

You're probably creating several hundred thousand array elements (what exactly is the display width/height?) which I definitely would not recommend. Why do you need data per-pixel?

Using lots of memory generally does not kill the FPS - are you using events to loop over the array every tick? That's what would kill the framerate.

I think I was using 640x480, but I think I had something on z as well so as you can imagine....

Any way I wasn't planning on doing per pixel, more like per tile... like displaywidth/sprite.width, I just forgot the tile size.

The thing is now that that's fixed this works perfectly fine starting with 32x32 tiles, but if I go down to 16 there is a noticeable drop in fps, and no its not in a loop.

Here's a cap if someone wants to verify

mine doesnt go down in framerate until 3 pixels

at 4x 4 it's still 60+

4200+ athlon x2

4 gigs 800MHz ram

Well that makes sense mines about 1/4th that. lol
