check through the tabs and perform all tests
Reference "Dxdiag", has it not changed though now and you cannot do tests. I know once upon a time, you could run tests, but now, there is no option to do so, you open it up, it has a little "think" and then you can save everything as a txt file etc, there is no stress testing etc on the graphics card for example. I have the latest version from what I can see (Windows 10) and checking online, my version matches all current screenshots etc. I have a feeling, it changed when Windows 10 come out.
