GpuTest

GpuTest is a useful utility which lets you check your computer’s GPU, by using several OpenGL methods.
This software tool does not require installing, meaning that you can easily copy the program files to any location on the hard drive, or even to a portable storage unit, such as a USB flash drive thus, enabling you to run GpuTest on any computer that you have access to. In addition to that, you should know the Windows registry and Start menu/screen are not going to be affected.
This app enables you to choose from a wide range of OpenGL checkups, including tessellation (TessMark), geometry instancing (GiMark), pixel shader (PixMark Piano and PixMark Volplosion), vertex shader (Plot3D) and simple 3D (Triangle) tests.
A plain and simple graphical user interface allows any type of person to work with GpuTest, even if they happen to be beginners or highly experienced. The main window includes a drop-down list which lets people pick the type of test they want to perform. They can choose to view the test in a fullscreen mode, enable on screen information and select or input the resolution of their screen.
It is important to keep in mind that most benchmarks are going to put some strain on your computer, and therefore it is going to run a bit slower. Once the test is over, the utility is going to display the CPU’s score and create a CSV file, for further analysis.
All in all, GpuTest is a piece of software that helps you perform benchmarks on your GPU. During our tests, we did not register any crashes or bugs.
