Fillrates

Hello,

I am experiencing something strange. I put together this little benchmark thing:

; Drawimage Fillrate Test
; Set GFX
Graphics 640,480,16,1

; Set temporary image
gfxBenchImage=CreateImage (640,480)
SetBuffer ImageBuffer(gfxBenchImage)
For t=1 To 1000
	Color Rand(255), Rand(255), Rand(255)
	Oval Rand(600), Rand (440), Rand(40), Rand(40),1
Next

; Do the fillrate test
SetBuffer BackBuffer()
L_Timer#=MilliSecs()
For t=1 To 20000
	DrawImage gfxBenchImage,0,0	
Next
L_Time#=MilliSecs() - L_Timer#

; Print result
Cls
Result# = (((2000*64*48) / L_Time#))
Text 10,10,"DrawImage: " + Result# + " million pixels per second"
Flip
WaitKey()

And my results are:
P4 2.6GHz, Radeon 9700Pro, WinXP: 2117 mpix / s
P4 2.53GHz, GeForce4, WinXP: 2282 mpix / s
AMD 1.1GHz, GeForce2, WinXP: 1084 mpix / s
P3 333MHz, TNT2, Win2K Server: 16340 mpix / s (<-- here is a problem??)

As you can see, the P3 is flipping out, but I don't know why yet. Those of you who want, please run this code on your PC's and report "Processor, GFX Card: <result>". I am hoping to find a pattern. Maybe it's the OS...

Athlon XP 2000+ (1.67ghz), Geforce 3 Ti 200, and only 1075.25 mpix/s

oh, and winXP, might be cuz i need to reboot, i'll reboot my system, and test when I get a chance to reboot :P

edit: also forgot to mention that this was ran in blitz2D, not plus

AMD Athlon 1.2GHz, Voodoo3 3000, Windows 2000
467.29 mpix/s full screen mode
479.82 mpix/s windowed mode

One thing: Since you do not use a fixed random seed, the code above will not be a very reliable benchmark, since the actual work performed on the test machines can vary greatly, depending on the random number sequence it gets assigned.

lol.

I get 271.0169 mpix/full screen

I have a Dell GX240.
1.8 GHz P4
WinXP Pro
1 Gig Ram
Radeon 7000 VE Family 32 MB

Nice business computer but Dell SUCKS as a gaming machine.

Thanks so far. I was advised to use Lockbuffer and Unlockbuffer just before and after blit loop, this greatly affected the speed my PCs blitted them, even though it shouldnt make that much of an impact. Those of you who got less than you expected would probably notice a big difference by adding that.

I am trying to get some sort of an idea what graphics cards are capable of so I can do a "recommended" settings function in blitz, but maybe I should simply base it on measured MHz speed and video memory instead, as these results are so different from each other.

Thanks,

1049.75 mpix on full screen

GeForce2 GTS
