+By default, Jan uses GPU acceleration.
+
+If you are experiencing this issue, you may need to download the latest Nvidia CUDA toolkit.
+
+> We weren't propagating CUDA issues in the old build.
+
+Steps:
+
+1. Download Cuda toolkit (versions 11.4+) from [Nvidia](https://developer.nvidia.com/cuda-downloads?target_os=Windows)
+
+1. Go to Settings > Advanced > Turn on GPU acceleration
+
+1. You may need to restart Jan
+
+1. Check in `System Monitor` that there is more (V)RAM now
+
+1. If the issue persists, please install the [Nightly version](/install/nightly) instead.
+
+1. If the issue persists, ensure your (V)RAM is accessible by the application. Some folks have virtual RAM and needs additional configuration.
