How to optimize Intel HD 4000 graphics on T430 so no tearing occurs?

Hello People of LinuxQuestions

Does someone have extensive experience on optimizing the Intel HD 4000 graphics card on a Lenovo Thinkpad T430 when it's the only graphics chip in the system?
(having tearing issues)

And is there a way so that the graphics memory and clock speed can ramp up to maximum specified usage when needed and use low power and memory when not needed for intensive tasks?
(It seems to use very little of the available memory).

Is there a way to see the exact maximum usage in the command line?

My graphics hardware info looks like this:

I use this file at /etc/X11/xorg.conf.d/20-intel.conf:

Code:

Section "Device"
	Identifier "Intel Graphics"
	Driver "intel"
	Option "TearFree" "True"
EndSection

This could also be added to a pre-existing xorg.conf

Try Intel gpu tools.

Also the latest driver (Xorg driver) for intel to come, version 3 would have great support for tearfree plus many other enhancements.
