I have an app that I need to run under 9x and NT4 (and eventually 2K too).
I have been developing and compiling against opengl32.dll on NT4. Performance is ok.
I want to run it on 9x well, but at the moment it runs like a dog. I tried copying opengl32 to the 98 machine and renaming to opengl (as one suggestion) but I get an missing function error.
What is the ‘recommended’ or best way to have a single exe for 9x and NT, and to achieve best performance.
