Mouse Lag?

Ok so my friend just bought a razer deathadder mouse and he is getting mouse lag when playing games.  It is only games when he is doing anything else it is fine.  The weird thing is that he has some cheap wireless mouse that came with a case, and that works fine.  We have tested multiple mice with his computer and all of them have the same problem.  We have researched the problem and we can find nothing.  The mouse also works fine on my computer so it is not the mouse.  Please quick reply!!!

Try removing synapse and re installing.  Also look up win 8 mouse lag fix. 

Also make sure games are using raw mouse input. Battlefield has a setting for this. 

the problem is that its not only the razer mouse so its not synapse

and we r on windows 7

 

Try playing your games without triple buffering or v-sync. V-sync with triple buffering creates a lot of input lag for me.

nothing its starting to piss us off....minecraft goes to like 3 frames when you move the mouse....

 

for the record.........you just had to run the game as admin...fml
