I made a program that has some moving objects, It seemed that they were moving a bit slow in the beginning since their moving vectors where quite big in relation to their positions, but I thought it was some openGL limiter or something. When I started mailing my friends(windows users) the link to the zipped file (which contains the .exe and the glut32.dll and a readme.txt) some of them said the it looks cool, and others said that the balls where spinning VERY fast.
I then thought it can't be because there pc's are that much faster, it had to be some setting. I've been reading about "vsync" and the "wgl" functions that can be used to set vsync, but some guys on these forums say that you should not change "vsync" unless you really need to. I this a good enough reason? to have my program run at the same speed on all windows computers, is very important to me, and I don't want to ask everbody to go change some setting in the control panel or graphics card options. I want to tell the program exactly how to look and how fast the objects must move in the code in a legit way.
If I do understand vsync and it is not to taboo to set it to "0", I would like to turn it of, so that the program draws as fast as it possibly can, and I can decrease my movement vectors, for even smaller position changes more often. Is this the right way of reasoning?
Here is the link I was forwarding to my friends:
The program code is very basic, maths, vectors, matrix stuff, trig. It uses double buffering, and glSwapbuffers at the end of my display function. I also use the following functions:
glutGameModeString( "1280×1024:32@75" );
Please. Go easy on me.
