Конечно. Оно и надо. И синхронизировать есть из чего.
Но тут речь о 30-ти - 40-ка fps на eeepc
А это уже не есть хорошо

*Refresh Rate*:  The rate at which your video card is sending complete 
screens from its frame buffer memory to your monitor, and the 
corresponding rate at which the monitor refreshes the whole image.  60hz 
= 60 complete refreshes per second.
*FPS*:  Frames Per Second, the rate at which your video card is drawing 
frames to its frame buffer. If the FPS is higher than than the refresh 
rate, then the extra frames are lost and tearing could occur.
*Tearing:*  A screen artifact characterized by the display updating the 
screen to a portion of a new frame and a portion of an old frame instead 
of the entire new frame.  The result can be best identified by jagged 
horizontal bands during scenes of constant diagonal motion.
*Vertical Sync:* The act of synchronizing the FPS rate to a multiple of 
the refresh rate. For instance, if the video card can output 79 FPS but 
the refresh rate is 60hz, the video card will time the drawing of its 
completed frames to the frame buffer to exactly 60 times a second.  If 
the video card is only capable of outputting 50 FPS and the refresh rate 
is 60hz, the video card will either stagger the output to span multiple 
monitor refresh cycles or it will reduce the frame rate to 30fps, so 
that each frame is sent to the monitor twice. Note that the refresh rate 
stays 60hz in this scenario, but the viewer will only see 30 unique 
frames every second.
