Game Smoothness

Technical Support
Hi fellas,
After installing Diablo 3 I had a trouble with it even starting as I got a window saying i had a D3D problem, after taking help from the forums I changed a few digits in D3Prefs and now it can actually start BUT, The problem is that now the game is unplayable, just really really slow and unplayable. Can anybody assist me ?
Thank a lot !
Hi :

If you're using a Razer mouse and/or keyboard, check if updating to Synapse-3 beta will help... if not uninstall the Razer Chroma SDK Core Components using Windows Settings or Control Panel. See https://us.battle.net/forums/en/d3/topic/20765737231 for details.
