How To Use SGSSAA With Crysis.

Post » Sun Apr 21, 2013 1:29 am

How about making Crysis look even better with Sparse-Grid Anti-aliasing? Here's how and why. Sparse-grid AA is an advanced form of anti-aliasing that's not officially supported but supported by first party tools such as NVIDIA Inspector.

Sparse-Grid AA will do:

    Remove aliasing just about anywhere in the image.

    Applies to textures which improved fidelity.

    Applies to transparent textures like foliage and significantly makes the palm trees look better.

    Significantly removes texture flickering and pixel crawling while the image is in motion.

    Improves fidelity of objects in the distance.

One down side is that you'll need to use the DX9 version of Crysis to get best results because negative LOD bias is not supported in DX10/DX11 yet, this will make the image sharper in DX9 mode.

Use LOD Bias -0.500 for 2x SGSSAA, -1.000 for 4xSGSSAA, -1.5000 for 8xSGSSAA.

Make sure Multisample AA modes match the SGSSAA modes, i.e 4x MSAA/4xSGSSAA

Use these settings in the NVIDIA Inspector. http://www.guru3d.com/files_details/nvidia_inspector_download.html

Here are two uncompressed images of Crysis using SGSSAA(over 5mb each when uploaded). Notes the posts are clear with no aliasing at all and distance objects are sharp with no broken lines. Note that you can even see the bars around the top of the big tanks clearly.

Requirements.

Over 1GB of VRAM depending on resolution, 1920x1080, DX9, High will use over 1GB of VRAM.

A midrange graphics card like a GTX 560 or ATI equivalent recommended.

Latest NVIDIA drivers recommended.

Performance impact is very high when using 4xSGSSAA or above but image fidelity improvement is very high.

Enjoy. :)
