don't cap the frame rate.
Turn on V-Sync
(V-Sync works fine as long as your video card can maintain 60FPS (min) at all times.
If it can't do 60FPS at all times then you get dropped to 30 but that shouldn't be a issue for you on this game.
Seriously I use v-Sync all the time, as long as my FPS stays at 60 it's fine.
People only turn it off to get MORE frames per second but it's defeated due to the timing issue when using a 60Hz refresh rate.
So their video card can do 130FPS in the benchmark but the a 60Hz monitor cant refresh the screen that fast. What ends up happening is that rather than matching a frame to a refresh cycle it advances more frames while the current screen refresh is still in progress. So you end up seeing tearing.
If your getting 130 FPS and v-sync is OFF... it's pointless because your monitor just can't refresh that fast. So you STILL see everything on the monitor at 60 FPS because those 130 frames get crammed into 60Hz.
The best senario - Gaming monitors that offer 144Hz for example never need the v-sync turned on. Why? Because if it's not matching, it won't matter, the screen refresh will happen so fast you won't be able to see any tearing. And your monitor will be able to display all of the; up to 144 FPS. Other possible solutions are variable refresh rate technology provided by nVidia or AMD.
