Good Job!

Haven't you slept.....

This version has fps's similar to the last version but for some reason looks smoother and more professional. I think it's of a quality that, when viewed in comparison to the Blitzmax demo, is a really good advertisement for PureBasic. Even at 1000 sprites the movement is nice and smooth, while the Blitz one is much slower and jerkier.

PB version is, as netmaestro says, better in quality and smoothness.

but i dont find the optimized version better

and if it is, we talk only 1 sprite. Another thing; pb version is directx, blitz is ogl. Imho opengl is faster, so lets see...

if you would just share the source so everyone could optimize

I took the time to attempt converting this to OpenGL & it's running pretty well here, mostly over twice the speed of ZSprite.

@ 100:
ZSprite: 332 fps
ZSpritevsPB0.7: 355 fps
OpenGL: 624 fps

@ 1000:
ZSprite: 37 fps
ZSpritevsPB0.7: 45 fps
OpenGL: 92 fps

Whilst ZSprite does lag behind, we should remember that it's an engine, so it has to do a lot more processing in the background (i'm not saying it couldn't be faster though!)

Hopefully that's done the job.

Very nice and VERY fast!

Overrules the blitz version in a single wink.
Is it assembly optimized or anything, or just pure pb and some ogl functions?

(and would YOU care to share the source for your pb-mates?)

Quite impressive, was it done using PB 4 and the OGL subsystem?

It's just PB 3.94 & OpenGL. I'm not entirely sure assembly optimization would help as it's the rendering that takes time.

It was *mostly* made from cuts & pastes from these very forums (much of which dated back to 2002!)

you can nearly always make something faster

I only get 32 fps for 700 sprites on PB using 50% cpu.

On Blitzmax I get 55 fps for 700 but using 100% cpu.

I only have an nvidia gf4 ti4600.

So blitz wins easily.

v0.8 uploaded

[ADD] Speed Level 2 implemented.

Compare FPS and CPU time with the Blitz zSprite demo and with the nativ OpenGL PB version again

Don't forget: PB is 'also an engine' for DirectX 7.
