Dangerous Rays first prototype version (Alpha 1) was first released in April 2014. During the 6 months following it's release it has received 16 updates adding more features, game content as well as fixing the most important issues found by players.
Alpha 17a is the latest update released for the prototype version. Since the beginning of 2015 Lonely Bits Games is working hard on the Alpha 18 update (brand new engine, gameplay code remade from scratch, much better art assets…) that will be released in Fall 2018 and will mark the end of the prototype phase and the beginning of the real Alpha phase for the game development.

This prototype version only feature a small amount of content and is designed to get some useful feedback from players so the Alpha 18 version can be a very nice core base to be expanded in the many years to come.

- Playing on a notebook or weak laptop is not recommended at all.
- We strongly recommend to update your graphic card drivers before playing the game.
- If you have a NVidia graphic card you need to have at least 195.xx drivers series to run the game properly.
- The game DOES NOT support integrated graphics chipsets yet (Intel HD graphics series).
- Playing with less than 4 GB of RAM on your system is not recommended as you can experience “out of memory” crashes.

OS: Windows 7, Windows 8 or Windows 10
Processor: 2.6 GHz Dual Core e.g. Intel Core i3
Memory: 6 GB RAM
Graphics: DirectX 11 capable graphic card with 2GB video memory (Nvidia GeForce GTX 760 / AMD R9 270)
Hard Drive: 5 GB available space

OS: Windows 7, Windows 8 or Windows 10
Processor: 3.0 GHz Quad Core e.g. Intel Core i5
Memory: 8 GB RAM
Graphics: DirectX 11 capable graphic card with 3GB video memory or more (Nvidia GTX 1060 / AMD R9 390)
Hard Drive: 5 GB available space

When you launch the game you will see the game main menu. Here you can adjust the game settings (graphics, input, sound settings…) or create a new procedurally generated world and start a new game session.

Here is a list of the game settings that you can find in the settings menu.



Here you can change the language of the game. Only Original (English) and French is available.


Mouse Sensivity

Control the global mouse sensitivity.

Mouse Smoothing

Control the global mouse smoothing coefficient.

Invert Mouse

If enabled then the up/down camera mouse look will be inverted.

Key Binding List

Here you can change the various key bindings according to your taste.


Screen Resolution

Here you can choose the screen resolution that you would like to use. Please note that the prototype version do not support windowed display mode.

Refresh Rate

Here you can choose your screen refresh rate.


If enabled, the frames being drawn will match the number of times your monitor refreshes itself every second. This can greatly reduce screen tearing effect but the game frames per second (FPS) will be capped.


Here you can choose the gamma/brightness of your display.


Control the Field Of View of the player camera (in degrees). A higher value than the default one will give you a better and wider field of view but the image will look distorted if you are going to far. Usually the default field of view is good enough.

Super Sampling

Supersampling is a spatial anti-aliasing method that is achieved by rendering the image at a much higher resolution than the one being displayed, then shrinking it to the desired size, using the extra pixels for calculation. The result is a downsampled image with smoother transitions from one line of pixels to another along the edges of objects.
Can give a nice visual quality boost.

Please Note

This setting is very costly in terms of performance. Unless you have a very good GPU it is recommended to leave this setting at 100%.
Anisotropic Filtering

Here you can choose the level of anisotropic filtering that you wanna use.

Object Render Distance

Change the distance in meters where the general 3D objects are being rendered.

Trees Render Distance

Change the distance in meters where the trees are being rendered.

Textures Quality

Control the rendered textures quality.

Shadows Quality

Control the rendered sun and lights source shadows quality.

Shadow Map Size

Control the size of rendered shadowmaps. A bigger size mean smoother shadows but a bigger negative performance impact on the GPU.


Enable/disable FXAA. FXAA is a anti-aliasing method that is using to smooth out the edges of 3D objects.


Enable/disable High Dynamic Range rendering.


Enable/disable Bloom effect rendering.

Cone Step Mapping

Enable/disable Cone Step Mapping. CSM is used to give the impression of great relief on some flat surfaces of 3D objects.


Enable/disable Screen Space Ambient Occlusion rendering.

Depth Of Field

Enable/disable Depth Of Field dynamic blurring effect.


Enable/disable Godrays (light scattering) effect.

Godrays Quality

Change the global quality of the Godrays effect.

Sun Lens Flare

Enable/disable sun lens flare visual effect.

Anaglyph 3D

Enable/disable the Anaglyph 3D rendering. This is only relevant if you have some red/blue glasses that are compatible with this effect.


Effects Volume

Control the global volume of the game sound effects. (footsteps, gunshots…)

Music Volume

Control the ingame ambient music volume.
