+# gpu-load
+
+Shows load of Nvidia or AMD GPUs.
+
+![](gpu-load.png)
+
+The four values are the load of the:
+
+1. The GPU it self
+2. The load of the VRAM of the Card
+3. Video buffer (NVIDIA only)
+4. PCIe bus utilization (NVIDIA only)
+
+`short_text` only shows the GPU load.
+
+# Dependencies
+
+Choose one depends on your GPU.
+
+* `nvidia-settings` Note that on Debian-based systems, you have to add `contrib` and `non-free` to your `sources.list` in order to install the package via your package manager.
+* [`radeontop`](https://github.com/clbr/radeontop)
