This forum is for support of Intel desktop boards. You should be contacting ASUS for support of your board.
The SMBUS controller issue can be ignored. No, your chipset is not a problem. You should be using the chipset inf (which is not a driver) provided by ASUS.
No, this is not the reason for your game and video issues.
Just ignore the SMBus issue.

To Al Hill: Thank you for your contribution.
DJ_OXyGeNe_8, I would recommend following Al's advice as the drivers should be provided by the motherboard's manufacturer.
In regards to the video quality ("games and video playbacks look choppy"), the processors for the X99 based motherboards don't have integrated graphics, so I would recommend to the manufacturer of the video card.
Hope this information helps.
