As Google Chrome, Fire fox, Internet Explorer and various other softwares around the world are being used to play games, chatting etc. There comes Raze 3 which requires fast computers, When i used to play Raze 3 in Google Chrome, it used to lagg a lot, but as i tried Opera, It works good but sometimes can get you killed also, But still I recommend you to try it and feedback me. Thanks-Sphinz.
I haven't tried opera, but R3 is pretty good in Firefox, if only the game itself didn't have so many bugs and glitches it would probably be ok on near all browsers.
