What is the difference between SSAO and HBAO?

Unlike previous SSAO variants, HBAO uses a physically based algorithm that approximates an integral with depth buffer sampling. This enables HBAO to generate higher-quality SSAO, increasing the number of samples per pixel and the definition, quality, and visibility of AO.

Is HDAO better than SSAO?

HBAO & HDAO

HBAO stands for 'horizon based ambient occlusion'. It is a step up graphically from the simpler screen space ambient occlusion. It ups the ante from every aspect in SSAO, giving the game better and higher definition, and visibility.

What does HBAO do?

HBAO+ is the Ambient Occlusion option of choice. Its image quality exceeds that of any other technique, it's the most-efficient full-resolution AO option, the first to use cache-efficient Interleaved Rendering technology, and the first to eliminate flickering and under-sampling artifacts.

What does SSAO do in games?

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.

Is HDAO better than HBAO?

HBAO and HDAO are essentially the same thing but different vendor specific implementations. SSAO is less accurate but improves image quality with a much smaller performance penalty. If you're going to use H*AO, from what I understand you should select HDAO if you have an ATI card or HBAO if you have an nVIDIA card.

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

Does 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.

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.

What is NVIDIA HBAO?

HBAO+ improves upon existing Ambient Occlusion techniques to add richer, more detailed and realistic shadows around objects that occlude rays of light.

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.

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 Bloom affect FPS?

Because your screen can only get so bright, video games can use the visual trick of “Bloom” to make bright light appear super bright. While this option doesn't have a huge impact on your framerate, it is often turned off.

Does VSync affect FPS?

Even when VSync is working well it's not perfect. It may affect the gaming experience as it reduces the frame rate till it finds the perfect balance, resulting in stuttering increases and input lag. It happens in all types of games but is most noticeable in fighting and shooter titles.

How to set SSAO in graphics?

To enable SSAO in your Frame Settings go to Edit > Project Settings > Graphics > HDRP Global Settings > Frame Settings (Default Values) > Camera > Lighting > Screen Space Ambient Occlusion.

What is SSAO in graphics?

Screen space ambient occlusion (SSAO) is a computer graphics technique for efficiently approximating the ambient occlusion effect in real time.

Why is ambient occlusion so expensive?

Ambient occlusion techniques are expensive as they have to take surrounding geometry into account. One could shoot a large number of rays for each point in space to determine its amount of occlusion, but that quickly becomes computationally infeasible for real-time solutions.

Why is GPU 3D so high?

High GPU usage can be caused by malicious code. One known issue is installing an untrusted app that uses your GPU in the background to mine crypto.

What is HBAO and SSR?

HBAO or Horizon-Based Ambient Occlusion is basically a better version of the SSAO (screen space ambient occlusion). It makes the game look more realistic but eats up resources so turn it off. SSR – Off. Screen Space Reflections are reflections that are created from what is in view of the player's screen.

Is ambient occlusion GPU heavy?

How demanding is Ambient Occlusion? We would consider a typical application of AO in a game to be mid to high in terms of how demanding it is. The typically frame rate hit you can expect when enabling Ambient Occlusion is between 5-10%.

Does lowering quality 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.

Does turning on HDR reduce FPS?

No, HDR does not lower your in-game FPS numbers on console, meaning you can still get those silky smooth frame rates that you are used to. While we don't recommend using HDR in fast-paced, action-packed, highly competitive multiplayer games, you technically could get lower FPS.

What are the most taxing graphics settings?

What has the most effect on FPS?

The graphics card and CPU are the most significant contributing factors to a game's frame rate or FPS performance. The computer's CPU sends instructions from programs to the graphics card.

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.
