 ### Unreal Engine
 
-**Windows, Linux**: Download the binaries for the environment of your choice from the [latest release](https://github.com/Microsoft/AirSim/releases). Some pre-compiled environment binaries may include multiple files (i.e. City.zip.001, City.zip.002). Make sure to download both files before starting the environment. You may need to concatenate both files to unzip them.

+Use [7zip](https://www.7-zip.org/download.html) to unzip these files. On Linux, pass the first zip file name as argument and it should detect all the other parts as well - `7zz x TrapCamera.zip.001`
 
 **macOS**:  You will need to [build it yourself](build_linux.md)
 
 ### Unity (Experimental)
+
 A free environment called Windridge City is available at [Unity Asset Store](https://assetstore.unity.com/) as an experimental release of AirSim on Unity. **Note**: This is an old release, and many of the features and APIs might not work.
 
 ## Controlling Vehicles
-Most of our users typically use [APIs](apis.md) to control the vehicles. However if you can also control vehicles manually. You can drive the car using keyboard, gamepad or [steering wheel](steering_wheel_installation.md). To fly drone manually, you will need either XBox controller or a remote control (feel free to [contribute](CONTRIBUTING.md) keyboard support). Please see [remote control setup](remote_control.md) for more details. Alternatively you can use [APIs](apis.md) for programmatic control or use so-called [Computer Vision mode](image_apis.md) to move around in environment using the keyboard.

 ## Don't Have Good GPU?
-The AirSim binaries, like CityEnviron, requires a beefy GPU to run smoothly. You can run them in low resolution mode by editing the `run.bat` file on Windows like this:

+The AirSim binaries, like CityEnviron, requires a beefy GPU to run smoothly. You can run them in low resolution mode by editing the `run.bat` file (if it doesn't exist, create it with the following content) on Windows like this:
+
+```batch
 start CityEnviron -ResX=640 -ResY=480 -windowed
 ```
 
 For Linux binaries, use the `Blocks.sh` or corresponding shell script as follows -
-```
+
+```shell
 ./Blocks.sh -ResX=640 -ResY=480 -windowed
 ```

 UE 4.24 uses Vulkan drivers by default, but they can consume more GPU memory. If you get memory allocation errors, then you can try switching to OpenGL using `-opengl`
+
+You can also limit the maximum FPS using the `simRunConsoleCommand()` API as follows-
+
+```python
+>>> import airsim
+>>> client = airsim.VehicleClient()
+>>> client.confirmConnection()
+Connected!
+Client Ver:1 (Min Req: 1), Server Ver:1 (Min Req: 1)
+
+>>> client.simRunConsoleCommand("t.MaxFPS 10")
+True
+```
