What is your video hardware, and are the drivers up to date?

My video hardware is AMD Radeon HD 6450 and i use Windows 7 service pack 1

Okay, what is the driver version for your video card?

He said 'OpenGL 4.2' which indicates an older one. This hardware supports GL 4.5 in its latest version. And yes, the 4.2 drivers are known to be bad.

if I update my version of opengl from 4.2 to 4.5 can affect the performance of my graphics card for bad?

It shouldn't. It should actually make your graphics card's performance better.

But, of course, it's AMD, so I wouldn't be surprised if your GPU suddenly underwent nuclear fission after updating your GPU drivers.
AMD drivers are baaaaaaaaaaad.

At least it should make the visual garbage go away. With AMD nothing is guaranteed, aside from regularly having some broken versions in-between.
