+# OpenCL Installation (optional but recommended)
+
+Vadere uses computer's video card to speed up some computations. Therefore, following OpenCL components should be installed:
+
+* the OpenCL Installable Client Driver loader also called ICD loader (Opencl.dll for Windows and libOpenCL.so for Linux)
+* drivers for your device(s) 
+
+Both should be offered by the vendor of your device (often there are also open-source solutions). The device can be a CPU as well as a GPU (recommanded). For example, if you have a NVIDIA GPU instaling your drivers should be enough to install both components. 
+Vadere will search for the best suiable device which is supported. On a desktop workstation this should be your video card (GPU). If there is no device supporting OpenCL Vadere will use a plain and slower Java-implementation instead. 
+
+Please, use following instructions to set up the OpenCL components for your operating system:
+
+* Windows: For further information using OpenCL on Windows read the paragraph Running an OpenCL application [click here](https://streamcomputing.eu/blog/2015-03-16/how-to-install-opencl-on-windows/).
