GP2X owners who can help ...

[AndyH]

Is there anyone out there that could run this code on their GP2X's and report back what Frame Rates you get?

Code (glbasic) Select Expand

SETSCREEN 320,240,0
LIMITFPS 60

GLOBAL mb,ma,mx,my

WHILE TRUE

MOUSESTATE mx,my,ma,mb
IF ma =1 THEN END

printfps(0,0)
FPS(TRUE,0,20)

SHOWSCREEN

WEND



FUNCTION printfps:l_x,l_y

STATIC fps_time,fps_counter,s_FPS,fps_temp
    fps_time = GETTIMERALL()
    fps_counter = fps_counter + 1
        IF (fps_time-fps_temp)>1000
                fps_temp = fps_time
                s_FPS = fps_counter
                fps_counter = 0
        ENDIF
PRINT s_FPS+" Frames",l_x,l_y
        RETURN s_FPS
ENDFUNCTION
FUNCTION FPS: SHOW,X,Y
GLOBAL     Seconds,Minutes,Hours,Days,FR,timeK,time1,frames
    timeK=GETTIMER();
    time1=time1+timeK;
    frames=frames+1;
    IF time1>1000;
        FR=INTEGER(frames); frames=0;
        time1=timeK-1000;
        Seconds=Seconds+1;
        IF Seconds>59; Minutes=Minutes+1; Seconds=0; ENDIF;
        IF Minutes>59; Hours=Hours+1; Minutes=0; ENDIF;
        IF Hours>23; Days=Days+1; Hours=0; ENDIF;
    ENDIF;
    IF SHOW=TRUE
        PRINT " FPS: "+FR,X,Y
    ENDIF
    RETURN FR
ENDFUNCTIONI've placed a LIMITFPS of 60 in the code.  There's nothing going on but a SHOWSCREEN (which I am guessing will be copying the whole backbuffer data to the display).

On my two pocketpc's (not particularly high spec) I get:

Mio = 32 FPS
Garmin = 42 FPS

Wondering what I should expect for the two types of GP2X?  I can compensate the speed for when the game runs as PocketPC/GP2X and Desktops.


Question for Gernot:- the SHOWSCREEN will not go any faster than my desktop refresh rate (60Hz) even when the LIMITFPS is set higher so it must be tied to the VBL.  Is it possible to add a command to not limit the the monitor refresh rate?  I know it will make the display more choppy, but useful to have in some scenarios (especially 3D).

60 frames
fps: 120

on my old gp2x mk2

That's a good speed!  BTW, ignore the second reading - it always seems to return double the amount (code taken from the FPS thread).

Thanks XaMMaX
