That's a huge slowdown. What was your previous driver version you had installed? Have you tried the maximum performance option in control panel? The 15.28 drivers have a low clock issue which is obviously fundamental for this driver series. It might explain your huge slowdown, you can check with GPUz if this is the reason.
The previous driver was the default witch was already installed on laptop when i bought it from an OfficeMax store. Don't know exactly witch one. There is a pic of the GPU-z result.
Hello Róbert Bús,
I understand you are having performance issue with the graphics driver from our side.
I see you are testing the driver 188.8.131.5232. Please note that we have a new driver available for your graphics controller. I suggest you installing the new driver we have by accessing the following link:
If during the installation of the Intel generic drivers you get this message: "driver not validated on this computer", go here for further instructions:
It is also important to mention that the drivers that we provide are generic drivers. If you are still having problems, another good option is to install the drivers from the system manufacturer since these drivers have been designed and created specifically for your system.
Just in case, here you have their contact information:
