I've tried two games runing UE3, 逆战 and CrossfireHD (AKA CF2). These two games all have different sensitivity when I playing on different polling rate. Is it because of the engine or the specific games? Then what's the reason of it and which polling rate to choose to avoid the inaccuracy?

could be an acceleration / smoothing issue

There's nothing inherently wrong the UE3, just the implementation of it. The issue is that the game can't handle the reports when they come too quickly, so in most cases lowering the polling rate will give you the correct sensitivity.

So that's why. It's still awkward when you have a high fresh rate monitor but a low report rate mouse  XD.
