low performance, better graphic card.... STRANGE!!!

OpenGL Development JOGL Development
#1

Hi to everyone !

I develop a game using JOGL and something very strange happens. :o

I have 2 PCs with the following bacic characteristics:

  • BASE STATION
    -2.0 GHz CPU
    -ASUS A9550 128 MB GRAPHICS CARD
    -max resolution: 1280x1024

  • LAPTOP
    -I.7 GHz Cetrino CPU
    -GeForce FX Go5200 64 MB
    -max resolution: 1280x800 (wide screen)

Although it seems that the base station can give better performance the opposite happens and i mean that the game in the base station runs very slowly. On laptop everything seems OK.

I tried to play with the resolution or with the options of the two graphics cards but nothing changes…

What is the reason for this strange mulfunction??? ???

Trying not to state the obvious, but ehm… updated your drivers?

Do the JOGL demos (like Gears) run well on your desktop?

As Riven points out, are you running the latest set of drivers on your desktop?

Frankly as far as I know the Radeon 9550 is a pretty old card while the GeForce FX Go5200 is pretty recent. I have a Quadro FX Go700 which I think is comparable to your Go5200 and haven’t had any problems. On the other hand, I know of co-workers who run into trouble sometimes with Radeon 9500 cards and lack of available functionality or hitting a software accelerated path in the drivers.

completely no change in anything…

I think that this card has some problems maybe…

You didn’t state what type of CPU you were using. If the base system is a Pentium4 it is just simply not comparable to the PentiumM, and unless your test cases are fill rate dependent (ie. complex shaders or lots of over draw), you are likely to be draw call limited (ie. CPU).

Chris is right, I think a 1.6GHz Pentium M (Banias core) is about as fast as a 2.4GHz Pentium 4, although it obviously varies depending on the sort of benchmark (markedly different CPU designs).
