Hello Mr. Diego. Thanks for your reply.
I would go back to most stable (for me) 2932 driver, Dec 2012, IF I could have found a way to disable "dynamic frequency" feature of HD 4000 through Windows. So that I can disable this feature just before I open the games or run applications. I don't want to run HD 4000 full capacity on idle, only in games and applications which those I believe HD 4000's driver does recognize as "not very graphic demanding games and applications".
The main reason I use newer versions (3071 and 3165) of the drivers that they actually can able up to frequency of HD 4000's core clock 350 MHz to 1.1 GHz (1.100 MHz) on certain games. This will have an huge impact to run the games and applications smoothly. However, regardless how much stable 2932 driver is, it can not able to up frequency to 1.1 GHz. The biggest problem in the driver for me. It behaviors like idle mode in the game and stuck at 350 MHz core clock. Therefore, the games and applications which those work with HD 4000 will not work smoothly. If I can fix this, I will happily go back to 2932 driver.
So... Is there way to disable this "dynamic frequency" feature that I mentioned above? Since I use laptop my BIOS has very limited features (thanks to HP) so I can not do that from there. Because of that I'm asking you to how can I do this through Windows. Is this possible? If it is I will be very happy. I will wait your answer. Thank you.
