 | Echtzeit - what heist the eigendlich ifs thereby circa software goes?
Echtzeit means NOT the something liquid or fliessend expires, or quite quick or slow. Echtzeit means for Programmer sooner, that it worry carry must that the program on each computer apparently in the same speed expires.
now Gibts but slow and fast computer, the a computer creates only 1 fps, another 10. If I means a ball fly let and say the it itself per Frame (durchlauf) circa a Pixel moving should, then runs the ball on unterschiedlichen Rechnern different quick. No Echtzeit!
Echtzeit means hierbei z.B., the one schaut How quick the computer operates - and the Schrittweite the Balles anpasst.
But this is not at all so simply - of my opinion to Gibts here different Lösungsansätze which but any to and detriments having. one could z.B. each second look How many Frames geschafft get, and the Schrittweite the Balles adjust. but sekündlich? Reicht the? No, it sees awful from. objectively must one look How long the latest Frame lasting - and each Frame The Schrittweite new to charge. but is the then always liquid? No - unfortunately neither. The ball would sometimes hopsen. means must one Dämmer since.
anyway, I Have the time here in this miniDemo displayed. the Window is skalierbar around the FPS To reduce - because the BitBlit need Yes longer (More cpu) so larger the window is. The ball ought to nevertheless, alike How big The anzeigefläche is, verhältnismäßig always The right speed stick to - so well It's all right.
I have to too a class built - heist FPS. whom Source Gibts later - if at all interest on it exists. The class have I me eigendlich built circa 3D-Apps - How z.B. WalkEngines in Echtzeit run out To let. Hierbei is it nähhmlich particularly important! the BallDemo is only to that Test. |

Wodrich | by me shrug it with 850 fps.
there question I wieso iFs letztes Testprogramm of what one fps lied has and not started...

RGH | On my job-computer in the firm come I only on 45 fps (has hold only graphic OnBoard) and the ball fly always gleichschnell ums Eck.
(BTW: the latest demonstration let itself too by me To dwell with the display 1.00000000 fps not started ... neither, as i a better Grafikkarte installed having. mandatory well yet einanderes trouble drin been his.)

| @Jörg: hang from the Fenstergröße ex, the window is skalierbar.
@Michael: the a is reines BitBlit, the others was OpenGL. |

@Jörg: hang from the Fenstergröße ex, the window is skalierbar.
very, this is already clear - but are it really Frames by second those showing or something other? |

RGH | Hi,
I have it now To dwell ausprobiert (NVIDEA 6200 with 128 MB). the behaviour is strange: If I the program starte, have I first of all a display of around the 600 fps (swaying so between 5xx and 7xx). once I the window but too only unmerklich larger or small (!) ziehe, weg The fps on ca. 50 back. make I it integrally small, soar on about 100 on, vergrößere I it maximum (1280 * 1024), weg tappt im dunkeln on 15 - 20 back.
