CompuBench CL 1.1 Desktop Edition



In order to run CompuBench CL, you will need the latest OpenCL drivers for your device.

As a start, you have to check the manufacturer of your GPU and CPU.

If you have an Intel CPU or GPU:

If you have an NVIDIA graphics card, you should visit the auto-detect utility webpage:
That will guide you through the installation process.

If you have an AMD graphics card, visit and download the latest driver.

If you have an AMD CPU and couldn't install the latest Catalyst version, try the APP SDK:

Supported OSX version: 10.9.1

Some notebook manufacturers do not permit manual software updates; in that case please contact your manufacturer.
