What is the use of SSAO?

The Screen Space Ambient Occlusion (SSAO) image effect approximates Ambient Occlusion in realtime, as an image post-processing effect. It darkens creases, holes and surfaces that are close to each other. In real life, such areas tend to block out or occlude ambient light, hence they appear darker.

How does SSAO affect performance?

Performance impact: High. A lower Radius value improves performance, because the SSAO Renderer Feature samples pixels closer to the source pixel. This makes caching more efficient. Calculating the Ambient Occlusion Pass on objects closer to the Camera takes longer than on objects further from the Camera.

Should I turn ambient occlusion on or off?

You would want to use ambient occlusion because it shows subtle variations in lighting and helps your eyes detect surface details that would otherwise be washed out or unnoticeable. Ambient occlusion is great for softening the overall lighting in your scene if it's too bright.

Does turning off ambient occlusion increase FPS?

Ambient occlusion decides if objects in the scene cast secondary shadows. This adds a fair number of soft shadows and complex depth indicators for your eyes to enjoy. This setting lands in the middle of performance hit to visual interest. It's nice to have, but will cost a few FPS.

What is the best ambient occlusion option?

SSAO – Screen Space Ambient Occlusion

Graphically impressive games, especially newer ones, may suffer in quality with this option. However, if you do not emphasize that with your gaming, this is probably your best bet. In short: It works well, sacrificing graphical quality while still looking good on older PCs.

Ambient Occlusion, SSAO, HBAO, VXAO - PC Graphics Settings Explained

Does ambient occlusion lower FPS?

The typically frame rate hit you can expect when enabling Ambient Occlusion is between 5-10%. There are exceptions though, such as Apex Legends. Poor implementation at launch mean Ambient Occlusion could cause you to lose up to 20% of your FPS in Apex Legends.

What does ambient occlusion quality do?

Ambient occlusion is a technique used in production to approximate the effect of environment lighting. Unlike the dull, flat look of local lighting models, ambient occlusion can add realism to a scene by accentuating small surface details and adding soft shadows.

Does ambient occlusion improve graphics?

Regardless of the technique, turning ambient occlusion down or off will increase your performance, and in some games, it will increase it by a lot.

How do I optimize my graphics settings?

What causes better FPS?

The most common reason for reduced FPS is graphics settings that create a larger workload than your hardware can handle. So how do you achieve better FPS? Getting a faster CPU, more RAM, or a newer graphics card is one solution.

What is an example of ambient occlusion?

For example, the interior of a tube is typically more occluded (and hence darker) than the exposed outer surfaces, and becomes darker the deeper inside the tube one goes.

What graphics settings are the most demanding?

By far the most demanding task for your graphics card is shadows and lighting. You may find them as separate settings — and in games like Call of Duty: Vanguard, split across several settings — but they work together. Shadows are demanding because they require your graphics card to render a second scene.

What settings affect FPS the most?

Anti-aliasing and shadows are usually the two biggest settings that affect FPS. Anisotropic filtering could also be a setting that can affect FPS depending on the game. Textures could affect your game based on what your CPU/GPU is, but as long as it's not a really low end one it won't affect it that much.

What is SSAO in games graphics?

July 2020) Screen space ambient occlusion (SSAO) is a computer graphics technique for efficiently approximating the ambient occlusion effect in real time. It was developed by Vladimir Kajalin while working at Crytek and was used for the first time in 2007 by the video game Crysis, also developed by Crytek.

What is ambient occlusion for FPS games?

Ambient occlusion is a shading technique that games use to emulate an render out how much light is hitting each point or object in a scene. Basically, it makes shadows and lighting more realistic and dynamic in games.

Does limiting FPS increase performance?

Limiting the frame rate not only saves power, but also reduces heat and noise, keeping your GPU cool and quiet. Power draw and efficiency is important to gamers.

How to maximize GPU performance?

Should ambient occlusion be on or off Nvidia?

AO in nvidia's settings is a generic AO shader you can use in games that are too old to use AO by themselves. It should be off for all newer games, but try it out in older titles and see what you think; in those games you often have enough headroom to enable most image enhancements.

What is the best anti-aliasing?

Morphological Anti-Aliasing (MLAA) and Fast Approximate Anti-Aliasing (FXAA) Also developed by AMD and NVIDIA, both techniques work in the same manner as mentioned above. MLAA and FXAA are the most popular anti-aliasing methods in the market due to their ability to sharpen graphics using less computing power.

Does lowering graphics increase FPS?

Lowering the resolution of a game can usually increase the frames per second. However, sometimes you don't get a FPS boost – either due to bugs, your CPU being unable to handle the increased speed, or certain games even rely on a set FPS for internal calculations that can't be changed.

Does lowering textures increase FPS?

It's not exactly the texture quality (texture size) that determines the FPS, but the GC's capability of handling them. A game will try to load all of the assets it needs for a particular scene into the GC's memory.

What is ray tracing in graphics?

Ray tracing is a rendering technique that can realistically simulate the lighting of a scene and its objects by rendering physically accurate reflections, refractions, shadows, and indirect lighting.

Should texture filtering quality be high performance or high quality?

Furthermore, the performance impact appears to be insignificant, but might be more significant on low-end GPUs. It is recommended that Texture Filtering - Quality be set to High Quality on medium and high-end systems, and High Performance on low-end systems under Global Settings.

Should I use VSync?

The answer is simple. If screen tearing interferes with your gaming experience and causes frequent screen tears, you should enable VSync. On the other hand, if you are facing input lag or a decreased frame rate, turning VSync OFF will be the correct alternative.
