GPU Caps Viewer is a tool that lets you monitor the activity of your graphics card.

For example, if you are a hardcore gamer or a web developer who uses demanding applications when it comes to graphics, this software can come to your aid.

The user interface of GPU Caps Viewer is standard. So, you can view various information about your GPU, including shader cores, BIOS, device ID, subdevice ID, GPU temperature, current and maximum clock, GPU load, driver, OpenGL, OpenCL, CUDA, PhysX and multi-GPU.

But you can also start an OpenGL or OpenCL demo, view the OpenGL version and its extensions list, the number of CUDA devices, core data (name, compute capability, shader clock, multi processors, warp and grid size etc) and memory data (e.g. total memory, shared memory, total constant).

Furthermore, you can check out OpenCL information, such as version, number of CL devices, type, compute units, clock, driver, global and local memory, 2D and 3D image size, work item sizes, constant buffer, maximum sampler, extensions, work group size, and more.

In addition, you can view system information (CPU, CPU speed, CPU cores, operating system, memory, current display mode, and more), as well as web links, validation data and active 3D applications. Information can be exported to TXT or XML.

The program uses a high amount of system resources and didn't freeze or crash during our tests. However, it doesn't contain a help file. But even if it did, first-time users would have a hard time comprehending its technical terms. Thus, we recommend GPU Caps Viewer mainly to power users.
