I will answer with the same level of details you gave us : yes, there is
most probably a solution.
Very helpful, isn't it?
This was not helpful at all, do you work for microsoft?
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.
