XP and Win98 compatibility problems

[developer24]

Hello,
I have written a 3D game engine on a win98SE platform, I get about 30 frames
per second. But on an winXP station I only get 3-1 frames perscond, it is
very choppy. I like to use OpenGL. Is there a solution to this problem?

I will answer with the same level of details you gave us : yes, there is
most probably a solution.
Very helpful, isn't it?

Re: XP and Win98 compatibility problems

I used Visual C++ 6.0

The point is that you did not provide enough information for anyone to
begin to guess what the problem is.

Some things and questions for you to think about:

1) XP requires more memory that 98. How much is on the 98SE machne?
The XP machine?
2) Is it the same machine?
3) Have you tested on multiple machines?
4) Have you verified that other processes aren't using all the CPU
time?
5) Is it the same video card?
6) What video card is it?
7) Are you running the same screen resolution?
8) Did you install the latest manufacturer's (NOT Microsoft's) driver
for the video card?
9) Do the XP drivers support Open GL?

The should at least get you started diagnosing the problem in your
code or on your system.

I know : This was a bit of humour to make you understand that, without
providing us with at least some details (eg, a minimal, compilable code
sample that reproduce the behaviour, or at least a description of your
program architecture), there is no way we can help.

Re: XP and Win98 compatibility problems

Hello, Yes it is the same machine for win 98 and win XP, and video card.
256megs of ram. I merely change the hard drive on the same machine I use.
The code is written in visual C++6.0. Are the lingos different for winXP? I
thought XP came with its own video driver for inteli740. It is an old video
card and they dont have a driver for XP. Even on a Gforce2 with xp drivers I
get low frame rates about 30 or less but on win98 I get about 100fps. People
have tried it in their machines, they have the same problem
(choppyness/slow). I have tried other people's programs 3d engines I get the
same problem. I like to use OpenGL, are the lingos different for XP? Is
win98 16bit system or 32? I thought it was 32bit system.
