That's a can of worms right there 10rand ;)
Frames per second (FPS), the ideal is 60, anything over that is a luxury.
30 FPS is about the minimum before you'll notice.
Some monitors can be configured to display at a faster or slower rate, although the standard rate is just fine. 60-somethings ((hertz? I forget!)) is the standard setting.
As for FPS rate, it depends a lot on the game and your system specs. Some games lean heavily on your graphics card, others use a lot of processing power and others use some of both. Plenty of RAM for both is useful.
What is meant by a game lagging, crackling and stuttering and what causes such issues?
Lagging is usually referring to an online game where the delay between server and client communication is noticable. Crackling varies, but I understand it as when parts of the screen, say your healthbar, flickers on and off. Stuttering is probably where the framerate drops to a very low level from an acceptable level (Your zipping along at 65 FPS, then suddenly drop to 12-15FPS for a second or two as everyone shoots at you, then back up to 65 FPS again when you die and they all cease fire.)
General steps to take:
1) Ensure you meet the Recommended Specs, not the minimum.
2) Ensure your Graphics Card Drivers are up to date, update them if not.
3) Double check you have the most recent DivX
4) Check for patches for the game (Try fileplanet, or just a google search - "%gamename patch" and a brief surf will usually do the trick)
5) Reboot before you play a game.
6) If the error persists, try playing with the game's options (assuming you can get that far) and turning down the settings to see if the framerate improves. If that yields no result:
7) Find people with the same problem and put your heads together.
You may have lots of problems trying to play older games, especially on Windows XP, despite the advertising. I know I have. *mourns the loss of Alpha Centuri*
