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.

What does SSAO do in video games?

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.

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.

Does SSAO use CPU or GPU?

SSAO does not use any CPU to work, which provides the gamer with a solid amount of visual eye candy for 1/4th of the output.

Does ambient occlusion affect 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.

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

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.

Why does high FPS look choppy?

Laggy and choppy graphics can be caused by graphics settings like V-Sync, Windows Game Mode, or even your game's settings. PC problems like thermal throttling and poorly optimized RAM can also cause problems with your game.

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.

Does CPU affect FPS more than GPU?

While your graphics card usually affects FPS more than your CPU, your CPU does affect FPS in many ways. It gives the GPU environment information for it to render, and it handles game logic such as calculations relating to your character's interactions with other in-game objects or characters.

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.

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.

Does lower FPS improve performance?

Frame rate is a measure of how smoothly games and graphically intense visuals display on your PC. If FPS is lower than your monitor's refresh rate, you may be able to improve performance.

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.

Do video gamers have better spatial awareness?

But experimental studies suggest that playing action video games might help people become more skillful in at least one visual-spatial task. Inexperienced people trained with video games have improved their mental rotation abilities (e.g., Green and Bavelier 2007; Feng et al 2007; Boot et al 2008).

Do games look better in HDR?

You can read even more about HDR in our dedicated explainer, but it essentially helps to expand the range of colour and contrast in an image or game, giving the image more depth and detail overall. This makes it ideal for games, as it makes the experience more immersive and potentially enjoyable for players.

Should I use noise reduction for gaming?

4 Noise Reduction

While this is useful if you are trying to watch something in Standard Definition, such as older games or films, noise reduction is not the best TV setting for PS5 gaming and other next-gen consoles. It's best left off whenever possible to keep the picture looking the best it possibly can.

How do I know if my CPU is bottlenecking?

The one you want to look at is “CPU Impact on FPS,” which should be 10% or lower. This number will tell you whether a mismatch between CPU and GPU is causing a bottleneck, and whether upgrading either component will resolve the issue.

Does RAM increase FPS?

RAM will boost your system's responsiveness, load the game faster, and improve frame rates. The exact amount of memory that you will need for gaming will be determined by the type of games you want to play and if you need to use any other applications at the same time.

Do games rely more on CPU or GPU?

Most of today's games ask a lot from the GPU, maybe even more than the CPU. Processing 2D and 3D graphics, rendering polygons, mapping textures, and more require powerful, fast GPUs. The faster your graphics/video card (GPU) can process information, the more frames you will get every second.

Is anti-aliasing good?

Among all of the graphics settings you need to tweak in PC games, anti-aliasing is one of the most important. It can tank your performance or make your game look terrible if harnessed incorrectly. But with a little guidance on what anti-aliasing settings to use, you can optimize any game in seconds.

What is the full form of SSAO?

Semicarbazide-sensitive amine oxidase (SSAO) is a multi-functional enzyme widely present in nature. It converts primary amines into their corresponding aldehydes, while generating H(2)O(2) and NH(3).

What is motion blur in games?

Motion blur can be one of the most important effects to add to games, especially racing games, because it increases realism and a sense of speed. Motion blur also helps smooth out a game's appearance, especially for games that render at 30 frames per second or less.

Why 60fps feels choppy on 144Hz?

Judder occurs when the frame rate of your game can't be evenly divided by your monitor's refresh rate. So, in this case 60 fps can't be evenly divided by a 144hz monitor but a 120hz could do it perfectly.

Why is my 99 FPS so low?

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.

How do I fix high FPS but not smooth?

If your video card has a refresh rate far beyond the monitor's, you might consider upgrading your monitor so its frame rate can match your video card. Otherwise, go to your graphics card settings and turn your VSYNC on which may be called Fast Sync, Enhanced Sync, or Adaptive Sync.
