2D drawing slow as hell

[xorc1zt]

yes this is faster (2500 fps) but this method is single buffered. just try with DrawText() and you will see the problem.

why decent speed on XP and not on seven ?

Wow 2500,
here only 540 FPS Windows 7 32
Video Intel G33/G31

Workstation: Win7 x86, Intel Xeon Quad Core, NVIDIA Quadro FX 580

54 FPS / xorc1zt
2.400 FPS / netmaestro

Do you really have to ask? It's common knowledge that Vista and 7 are slower and more bloated than XP. You're now experiencing it firsthand.

Which isnt true at all.

You would be better off using bitmapped fonts instead of DrawText if you are using DX/OpenGL.

not convinced. as i already said i got 1000 fps with java.

pygame 800 fps

It's slow because you're using StartDrawing each iteration of your loop. You will get better results by creating a sprite outside of your loop and then using DisplaySprite instead.

No, he's not. There's only Box() inside the For/Next loop.

[xorc1zt]

how i can draw random rectangles with a sprite and without box() ? this code has nothing wrong, purebasic just can't do it on windows 7.

[Nituvious]

Well anyway, this is what I meant.

Code: Select all

#screenwidth   = 640
#screenheight  = 480

#TOTALBOXES = 100 ; change me to display more boxes

InitSprite()
OpenWindow(0, 0, 0, #screenwidth, #screenheight, "PB Drawing", #PB_Window_ScreenCentered | #PB_Window_MinimizeGadget)
OpenWindowedScreen(WindowID(0), 0, 0, #screenwidth, #screenheight, 0, 0, 0, #PB_Screen_NoSynchronization)



;bufferaddress.i = 0
;StartDrawing(ScreenOutput())
;bufferaddress = DrawingBuffer()
;StopDrawing()

fpscounter.i  = 0
timer.i       = 0
fps.i = 0
frames.i = 0
totalTime.l = 0
curTime.l = ElapsedMilliseconds()

Dim sprites.l(201)
For i = 0 To 199
	Debug i
	w = 1+Random(320)
	h = 1+Random(240)
	sprites.l(i) = CreateSprite(#PB_Any, w,h)
	Debug sprites.l(i)
	StartDrawing(SpriteOutput(sprites.l(i))) ; -- Random crash here? what the crap?
	Box(0,0,w,h, Random($FFFFFF))
	StopDrawing()
Next i
    
Repeat
  
  lastTime = curTime
  curTime = ElapsedMilliseconds()
  totalTime + (curTime - lastTime)
  If( totalTime > 1000 ) 
    totalTime - 1000
    fps = frames
    frames = 0
  EndIf
  frames + 1
  
  ClearScreen(RGB(0,0,0))
  For x = 0 To #TOTALBOXES
  	DisplaySprite(sprites.l(Random(#TOTALBOXES)), Random(320),Random(240))
  Next
 
  StartDrawing(ScreenOutput())
  ;For i = 0 To 20
  ;  Box(Random(320), Random(240), Random(320), Random(240), Random($FFFFFF) )
 ; Next i
  DrawText(20,430,Str(fps))
  StopDrawing()

Hi Nitu. I think it crashes when your w or h = 0.

[Nituvious]

Hi Nitu. I think it crashes when your w or h = 0.

Ah, you're right. I forgot all about that! Thank you. I edited my above post.

Hi,

have on my PC Windows XP and Windows 7. For 2d and 3d i make my own Endgine, the mp3d Engine.

For now i have tested it on the Windows XP and Windows 7 partition with PB 4.51, With PB dx9, PB Open Gl and ith PB MP3d as x86 and x64 version

The different between Windows XP and Windows 7 are very big! I don't know the reason but i hope anybody have a idea or solution?

You can load and test the program if you want:
