H*AO offers better quality but with an increased performance hit. 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.
What is HBAO?
HBAO, short for Horizon Based Ambient Occlusion, was the next enhancement in graphic rendering techniques. NVIDIA introduced this approach to address the grain and noise that came with pixel depth measurements of SSAO. It does so by considering the ambient light and the environment instead of just the pixels.
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. 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 VXAO?
One of these features has been left with too little attention: the ambient occlusion mode, or VXAO as we call it. The idea is simple – we remove the lighting part and keep only the occlusion part.
Does SSAO hurt performance?
Does ambient occlusion affect CPU performance? No, screen space ambient occlusion (SSAO) doesn’t affect your CPU at all. It only requires GPU resources to work and in fact, game optimization and constantly releasing better graphics cards have made its impact very small compared to other game settings.
Does ambient occlusion affect FPS?
So far the only thing that works is turning Ambient Occlusion up to High or Ultra, which eliminates the fps drop in confined areas but replaces it with a general fps drop for the whole game.
Is HBAO screen space?
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 Z Blur do?
Z-blur – This setting blurs your image whilst turning your head or running. Just turn it off. Noise – Noise adds a film grain effect. Having it on doesn’t really improve anything, but switching it off, will make the game look better.
Should I turn tessellation off?
Generally speaking, tessellation is a nice addition to games but it’s not mandatory for gamers. Under typical circumstances, visual differences are hard to spot, so you can safely disable it to help boost performance. Of course, there is no reason to do that if your GPU is powerful enough.
Should I turn on ambient occlusion?
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.
Is it better to have depth of field on or off?
Depth of field is a setting that highly depends on the player. It can make the game look more realistic but it also adds blur in the background which is something that many players despise. Additionally, depth of field is GPU intensive so turning it off can save you a couple of FPS.
What triple buffering does?
With triple buffering enabled, the game renders a frame in one back buffer. While it is waiting to flip, it can start rendering in the other back buffer. The result is that the frame rate is typically higher than double buffering (and Vsync enabled) without any tearing.
Should you turn on anti-aliasing?
Should I Turn Anti-Aliasing On or Off? If your visuals look great and you have a high-resolution display, you don’t need to turn on anti-aliasing options. Anti-aliasing is for people who experience those unsightly “jaggies” and want to smooth out the edges of their graphics.
Should I turn on VSync?
So, should you turn VSync on or off? If you’re seeing a lot of screen tearing and you want it to stop, then you should turn VSync on. If you’re experiencing severe input lag or dropped frames with VSync enabled, then you should turn it off. But in most instances, VSync shouldn’t present any problems.
Is ambient occlusion CPU or GPU?
HBAO is a post processing effect also designed to add realism to scenes by highlighting surface details and reproducing a reduction in light due to occlusion. HBAO arguably delivers more accurate AA than SSAO and, these days, is highly tuned to use minimal GPU time.
Does SSAO decrease FPS?
I can switch between SSAO, HBAO, and HDAO on Blood Dragon, for example, and see no real difference. And additionally, there seems to be a significant drop in performance – sometimes the difference between 60 and 45 FPS – if I use the different types of AO.
Which anisotropic filtering is best?
It’s hard to imagine a situation where you shouldn’t use anisotropic filtering as it dramatically improves image quality without compromising performance. Just stick to 8x and 16x anisotropy levels and enjoy sharp, clearly visible textures at all camera angles.
Should I turn on motion blur?
The quick answer is that you should turn motion blur off if you’re playing a first person games and you want to be as quick and effective as possible. It’s good to switch off for competitive gaming, though it can come at a cost when it comes to how visually impressive the game is.
