V-Sync is one of the video options on Trainz 12. I had no idea what it did until I read this excellent explanation. Now you too can grok. http://www.pcworld.com/article/229024/geek_101_what_is_vsync.html
In a related note, when I first played Crysis I noted the manual recommended going in to Task Manager on the PC and ending all processes except task manager itself and explorer (why explorer I don't know). Of course, in my case, I leave the Steam thingie running also if I'm playing a Steam game. This is supposed to help your game run better. I do this for all my games/sims. Does anyone else do this?
