Garry’s Mod How to Enable Ambient Occlusion for NVIDIA Users Guide 1 - steamsplay.com

A step-by-step guide on explaining how and why to enable Source Engine’s AO implementation.

You can do this by searching on Windows 10 “dxdiag”, which will showcase a list of information regarding your computer’s software, firmware, and hardware. To find out the GPU you’re using, go to one of the display tabs and see if any of the names include “NVIDIA GeForce”. If it does, then this guide is completely feasible for you! If not (AMD Radeon, Intel, etc.), then unfortunately you will have to research for alternatives to NVIDIA Inspector if they exist.

Ambient occlusion is a shader which calculates how exposed surfaces are in 3D space. AO is commonly adjusted depending on the ambient lighting of the scene, so if the sun was directly facing a particular part of the building, those darker surfaces would become less severe as a result of increased exposure. The same logic can be applied if the light source itself was dim and produced little to no illumination, surfaces would appear darker, mostly in corners or areas of the surface where light is less prominent.

Ambient occlusion can provide significant graphical improvements to any video game, most notably older titles like Garry’s Mod. This is because it adds depth to surfaces and makes everything look and seem more realistic. From my experience, enabling AO had no noticeable impact on performance using a NVIDIA GeForce RTX 2060 Super, but it may be different to users who have a less powerful machine. The process of enabling it is also free and fast, so why not at least give it a try?

Go to the download page – [guru3d.com]  for NVIDIA Inspector and scroll down until you see “Download Locations”. Choose whatever location you would like to download the file from and wait 5 seconds for it to start. Once you’ve downloaded the program, extract the .rar file using a file archiver such as 7-Zip – [7-zip.org]  or WinRAR – [win-rar.com] . Launch “nvidiaProfileInspector.exe” and click “yes”.

In order to enable ambient occlusion for Garry’s Mod, we must consider which version of the game you’re using:

  1. If it’s the main/default branch of the game (non-chromium), click on the arrow pointing down next to the search bar for profiles on the top left to open the drop-down menu, and scroll down until you find “Half Life: Source”. Select it and beside the arrow you pressed earlier, find one of the buttons that say “Remove application from current profile”. Click on the arrow pointing down next to that and hit the cross next to “hl2.exe”, then apply your changes. This will make it so the two don’t conflict as the executable for the main branch of Garry’s Mod shares the same name as Half Life: Source.
     

    Return to the profiles drop-down menu and find “Garry’s Mod”. Where it says “Ambient Occlusion compatibility” at the top of the list, select the button for the drop-down menu to the far-right and find “0x0000000A (Half-Life 2, Half-Life 2: Deathmatch)”. Now, scroll down to “5 – Common” and select the drop-down menu for “Ambient Occlusion setting”, and choose whatever mode you desire. Do the same for “Ambient Occlusion usage” and enable it. Make sure to apply your changes and now you’re done with NVIDIA Inspector!

  2. If it’s the beta branch of the game (chromium), click on the arrow pointing down next to the search bar for profiles on the top left to open the drop-down menu, and scroll down until you find “Garry’s Mod”. Select it and beside the arrow you pressed earlier, find one of the buttons that say “Add application to current profile”. Click on it and browse to where you installed Garry’s Mod and choose “gmod.exe”, then apply your changes. If you don’t know the location, you can find it by right-clicking on Garry’s Mod in your Steam library, selecting properties – local files – browse – bin – gmod.exe.
     

    Where it says “Ambient Occlusion compatibility” at the top of the list, select the button for the drop-down menu to the far-right and find “0x0000000A (Half-Life 2, Half-Life 2: Deathmatch)”. Now, scroll down to “5 – Common” and select the drop-down menu for “Ambient Occlusion setting”, and choose whatever mode you desire. Do the same for “Ambient Occlusion usage” and enable it. Make sure to apply your changes and now you’re done with NVIDIA Inspector!

 

You’ll notice the AO implementation may flicker or not even work despite following the guide. That’s because there is one more step to do: enabling the “Toy Town” effect from the post process tab. If you don’t want the effect from Toy Town, lower the values to 0 so they wont appear. Enjoy!

gl ssao

This sample implements screen space ambient occlusion (SSAO) using horizon-based ambient occlusion (HBAO). You can find some details about HBAO here. It provides two alternative implementations the original hbao as well as an enhanced version that is more efficient in improved leveraging of the hardware's texture sampling cache, using de-interleaved texturing.

sample screenshot

Note: This sample provides an improved HBAO algorithm, however it is not same as HBAO+ which is part of NVIDIA ShadowWorks and improves the quality and performance of the algorithm further.

HBAO - Classic:

  • To achieve the effect a 4x4 texture that contains random directions is tiled across the screen and used to sample the neighborhood of a pixel's depth values.
  • The distance of the sampling depends on a customize-able world-size radius, for which the depth-buffer values are typically linearized first.
  • As the sampling radius depends on the pixel's depth, a big variability in the texture lookups can exist from one pixel to another.
  • To reduce the costs the effect can be computed at lower-resolution and up-scaled for final display. As AO is typically a low-frequency effect this often can be sufficient.
  • Dithering artifacts can occur due to the 4x4 texture tiling. The image is blurred using cross-bilateral filtering that takes the depth values into account, to further improve quality.

HBAO - Cache-Aware:

  • The performance is vastly improved by grouping all pixels that share the same direction values. This means the screen-space linear depth buffer is stored in 16 layers each representing one direction of the 4x4 texture. Each layer has a quarter of the original resolution. The total amount of pixels is not reduced, but the sampling is performed in equal directions for the entire layer, yielding better texture cache utilization.
  • Linearizing the depth-buffer now stores into 16 texture layers.
  • The actual HBAO effect is performed in each layer individually, however all layers are independent of each other, allowing them to be processed in parallel.
  • Finally the results are stored scattered to their original locations in screen-space.
  • Compared to the regular HBAO approach, the efficiency gains allow using the effect on full-resolution, improving the image quality.

MSAA support:

  • The effect is run on a per-sample level N times (N matching the MSAA level).
  • For each pass glSampleMask( 1 << sample); is used to update only the relevant samples in the target framebuffer.

Blur:

  • A cross-bilteral blur is used to eliminate the typical dithering artifacts. It makes use of the depth buffer to avoid smoothing over geometric discontinuities.

Performance

The cache-aware technique pays off on larger AO radii or higher resolutions (full HD).

Timings in microseconds via GL timer query taken on a Quadro M6000, no MSAA, 1080p (sample default is 720p, which may give less difference between the two).

Classic

Cache-Aware

Sample Highlights

The user can change MSAA settings, blur settings and other parameters.

Key functionality is found in

  • Sample::drawHbaoClassic()
  • Sample::drawHbaoCacheAware()

As well as in helper functions

  • Sample::drawLinearDepth()
  • Sample::drawHbaoBlur()

The sample contains alternate codepaths for two additional optimizations, which are enabled by default.

  • : Depth is stored with the ssao calculation, so that the blur can use a single instead of two texture fetches, which improves performance.
  • : In the cache-aware technique we update the layers of the ssao calculation all at once using image stores and attachment-les fbo or a geometry shader with layers, instead of rendering to each layer individually.

Building

Ideally, clone this and other interesting nvpro-samples repositories into a common subdirectory. You will always need nvpro_core. The nvpro_core is searched either as a subdirectory of the sample, or one directory up.

If you are interested in multiple samples, you can use build_all CMAKE as entry point, it will also give you options to enable/disable individual samples when creating the solutions.

Providing Pull Requests

NVIDIA is happy to review and consider pull requests for merging into the main tree of the nvpro-samples for bug fixes and features. Before providing a pull request to NVIDIA, please note the following:

  • A pull request provided to this repo by a developer constitutes permission from the developer for NVIDIA to merge the provided changes or any NVIDIA modified version of these changes to the repo. NVIDIA may remove or change the code at any time and in any way deemed appropriate.
  • Not all pull requests can be or will be accepted. NVIDIA will close pull requests that it does not intend to merge. The modified files and any new files must include the unmodified NVIDIA copyright header seen at the top of all shipping files.

How to Enable NVIDIA Ambient Occlusion in my Game

From my understanding and research on the topic, enabling ambient occlusion on the control panel does not make your NVidia card do some voodoo magic and apply AO to your scene. That's the way I read it from this page.

All of the games built on Valve’s Source engine support AO when enabled from the CP

Instead it's an option that gets signaled into your application, for example AO is set to off, and you deal with that setting in your application. With the example you would disable AO.

It makes sense when your options are , or where are just in-game settings.


So how could you acehive this with your appliction? You would need to use NVAPI.

There is some documentation here and an API reference here. The documentation actually shows you how to change the VSYNC global settings (p.8).

Unfortunately I could not get it working on a application basis. Although I did manage to get applications that exist in the program settings via , just remember to set before you pass it to the function.


Upon more research I have found NVidia ShadowWorks, which looks like it might be promising.

Hope this points you in the right direction.

Occlusion nvidia ambient

The gaming industry is thriving thanks to technological advancements in hardware, processing power, and graphics. With new generation graphics cards, many gaming companies strive to deliver increasingly realistic ambient lighting. Gamers know that there are a lot of graphics settings they can play with to make the game visually appealing and more dynamic, such as ambient occlusion.

So, what isambient occlusion?

This guide provides an overview of this setting and details different types of it.

What Is Ambient Occlusion?

What Is Ambient Occlusion

Ambient occlusion is a rendering method that provides an approximation of how bright the light should be at different parts of the visible surface. It considers different factors such as the environment of the game and the position of the light source. It provides a realistic simulation of the shadowing objects that block the ambient light from different sources, adding realism to 3D video games by mimicking light distribution in reality.

Ambient occlusion first surfaced in The movie Pearl Harbor introduced it for the very first time. Although it wasn’t a masterpiece, it helped pave the way for gaming graphics to rise.

Ambient occlusion in the gaming industry was first introduced in The game development company Crytek introduced it in their game Crysis, which earned a lot of accolades and sold over 3 million copies.

However, given that the shadowing was too graphically demanding for many gaming machines in the s, a lot of gamers couldn’t benefit from this feature until much later. Nevertheless, many still enjoyed the realistic pinch that the game had to offer.

Much like any other technology, ambient occlusion has improved over time. Below are some different types of it.

Types Of Ambient Occlusion

The Witcher 3 Ambient Occlusion None

Different graphics cards and their architectures and rendering technologies contributed to various ambient occlusion enhancements, so there are different types prominent in today’s titles.

Some of the most commonly found settings include SSAO, HBAO, HDAO and VXAO.

SSAO

The Witcher 3 Ambient Occlusion SSAO

SSAO or Screen-Space Ambient Occlusion was the type of occlusion introduced by Crytek in their debut of Crysis. However, to save the processing power, SSAO doesn’t consider the space and elements that produce shadows.

Instead, SSAO looks at the pixels around the element and their depth, which makes CPU usage more efficient, while introducing a dynamic rendering to make the ambient more realistic.

That said, instead of focusing on the entire screen, SSAO measures ambient occlusion in pixel depth at a part of the screen. Still, that brings some drawbacks, such as noise and potential inaccurate shadow distribution if the pixels aren&#;t properly measured.

SSAO didn’t have loading times, which made games run smoother. However, graphics card performance and video game demands have increased over time, which brought in new techniques.

HBAO

The Witcher 3 Ambient Occlusion HBAO+

HBAO, also known as 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 and the environment instead of just the pixels.

With the help of geometry, it&#;s much more effective at rendering shadows and lighting. The major disadvantage of HBAO is that, unlike SSAO, it requires more processing power in both the CPU and GPU. Later on, HBAO+ was featured to provide a less performance-tasking algorithm of light and shadow sampling.

HDAO

What Is HDAO Ambient Occlusion

HDAO or High Definition Ambient Occlusion is a similar technique, although it&#;s meant for AMD graphics cards to compete with Nvidia’s HBAO. There’s no difference between HBAO and HDAO, except that they’re native to their respective distributer&#;s GPU.

VXAO

What Is VXAO Ambient Occlusion

VXAO, or Voxel Ambient Occlusion, is the closest video games can get to reality in terms of lighting and shadow rendering. However, not many games boast this setting, mainly because it’s too tasking and will push the limits of your processor and graphics card. It also has a different approach than SSAO and other techniques.

In short, VXAO will render geometrical objects and approximate the shadowing outside the scene you’re experiencing. This approach gives scenes an even more realistic touch, providing a great comparison between modern-day games and what video games used to look like in the past.

More technically put, VXAO converts pixelated objects on the screens into voxels, which are 3D, cube-shaped pixels, hence the voxel ambient occlusion. As a result of their 3D structure, voxels can estimate the dimensions of certain geometrical objects inside games, which results in precise and sleek light and shadow rendering.

Ambient Occlusion vs. Ray Tracing

Ambient Occlusion vs Ray Tracing

SSAO focuses on pixel-depth and doesn’t take shapes and objects into account, leading to darkened corners, grain, and inaccurate shadows. On the other hand,Ray Tracing, being a more recent technology, focuses on more factors like the geometry of different shapes and objects, surfaces, and light to render accurate and realistic shadows.

It’s also a step forward from HBAO and HDAO, which focus purely on geometry. Additionally, Ray Tracing processes and renders only what’s visible to the player. In other words, the approximation of lighting and shadows is only performed on the camera view field.

Currently, not too many gamers use Ray Tracing, mostly because the feature is native to RTX , and RX cards, and only a handful of games support this next-generation feature. However, as the gaming industry is progressing more games will support this technology.

Conclusion

Ambient occlusion is a method that calculates and approximates the right brightness in the in-game ambient, bringing players closer to the digital world. Different types of ambient occlusion have been developed throughout the years together with new graphics.

While more occlusion methods such as Ray Tracing will inevitably emerge, it’s important to note that ambient occlusion isn’t the only way to make your game look closer to reality. Still, it’s a complex yet fascinating technique which undoubtedly enhances both games and movies.
