Most of the graphics settings can be adjusted using the
Resolution and mode
You can find the
Resolution and mode configuration under the
Display mode – select between fullscreen mode and windowed mode. In the case of full screen, you can choose the resolution from a list of supported resolutions in a drop down menu. If you choose windowed mode, you can enter the resolution you want. You can also choose whether the window should be resizable or not. In order to switch from full screen mode to windowed mode during the execution, use the key
V-sync – enable v-sync to limit the frame rate to the refresh rate of your monitor. In some cases this may help reducing tearing.
Maximum frame rate – it is possible to set a maximum frame rate by ticking this checkbox and entering a positive integer value. The frame rate will be capped to that value.
This setting governs the size of the textures, the complexity of the
models and also the quality of the graphical effects (
lens flare, etc.). Here are the differences:
Low – very low resolution textures, mostly 1K (1024x512), and fewer sample counts for the visual effects than in higher quality settings.
Normal – moderately low resolution textures (2K when available). The graphical effects use a reasonable amount of quality for nice visuals without compromising the performance too much.
High – high-resolution 4K (3840x2160) textures. Graphical effects use a large number of samples.
Ultra – very high resolution textures (8K, 16K, etc.).
Graphics tab you can also find the antialiasing
configuration. Applying antialiasing removes the jagged edges of the
scene and makes it look better. However, it does not come free of cost,
and usually has a penalty on the frames per second (FPS). There are four
main options, described below.
Find more information on antialiasing in the Antialiasing section.
If you choose this no antialiasing will be applied, and therefore you
will probably see jagged edges around models. This has no penalty on
either the CPU or the GPU. If want you enable antialiasing with
override application settings in your graphics card driver
configuration program, you can leave the application antialiasing
setting to off.
FXAA – Fast Approximate Antialiasing
This is a post-processing antialiasing which is very fast and produces reasonably good results. It has some impact on the FPS depending on how fast your graphics card is. As it is a post-processing effect, this will work also when you take screenshots or output the frames. Here is more info on FXAA.
NFAA – Normal Field Antialiasing
This is yet another post-processing antialiasing technique. It is based on generating a normal map to detect the edges for later smoothing. It may look better on some devices and the penalty in FPS is small. It will also work for the screenshots and frame outputs.
Style to render the orbits.
Use line style – use whatever style is defined in the
GPU VBOs – very fast, but slightly inaccurate and bad-looking. Enable for performance, as everything is done in the GPU.
Select the line rendering backend.
GL lines – use the line primitives offered by the graphics driver. Quite fast.
Polyline quadstrips – use polygon lines. Better looking but slower.
Select the amount of bloom to apply to the scene.
Activate the pseudo lens flare effect.
Activate the motion blur effect.
Choose the way elevation (height) is represented in Gaia Sky.
Tessellation – use geometry subdivision.
Parallax mapping – use parallax mapping in the fragment shaders.
None – do not represent elevation.
Enable or disable shadows, and choose their properties.
Shadow map resolution – choose the resolution of the shadow map textures to use.
# shadows – how many shadows are active at a time in the scene.
Control the image levels
Brightness – overall brightness of the image.
Contrast – overall contrast of the image.
Hue – hue value of the image.
Saturation – saturation value of the image.
Gamma correction – gamma correction value of the image. This should be calibrated with your monitor.
HDR tone mapping type – tone mapping algorithm to use. Choose
Automaticto use a real-time adjusting mode based on the overall lightness of the image. All the others are static algorithms.
