OGSSAA is a type of anti aliasing that involves sending a higher-than-native resolution signal to your monitor, then downsampling it to native resolution to improve image quality. It won't help with text, but for gaming you may be surprised at the difference!

The video explains the concept of original gangster supersampling anti-aliasing, or ogssaa, and why it can improve visual quality in games by rendering at a higher resolution than the monitor supports and then downsampling to the native resolution. It emphasizes that ogssaa is a full-image upscale technique, not just edge smoothing, and notes that while it can substantially enhance image quality, it is relatively inefficient compared to traditional anti-aliasing methods. The host also discusses practical reasons to use ogssaa, such as when a game lacks good AA options or when forcing AA through drivers may not be effective. The presentation frames ogssaa as a method to push the hardware and enjoy crisper visuals, sometimes at the cost of a portion of frames per second, and it highlights that this approach pairs well with other AA types for mixed results. There is also guidance on where to find community resources and guides for both nvidia and amd users, and a reminder that the 780 Ti was used to demonstrate the technique without stressing lower-end hardware. The first actionable segment walks through configuring the Nvidia control panel to enable custom resolutions, including step-by-step checks to override in-game scaling and to create non-native resolutions such as 2560x1440 and even 4k-like 3840x2160, with notes on stability and the potential need for forum help. The second major portion discusses the observed performance and visual outcomes, comparing downsampled 2560x1440 to 1080p with MSAA and showing example images, while encouraging viewers to share their own results on the forum to build a small database of setups. The video concludes with practical tips for testing, seeking feedback, and engaging with the community to refine these configurations, while also teasing sponsor content and encouraging discussion in the forum for broader testing and documentation.

Questions answered

What is ogssaa and why would you use it?
OGSSAA is an upscaling technique that renders a game at a higher resolution than the monitor supports and then downscales to the native resolution, improving image quality while trading some performance. It is useful when games lack strong AA options or when forcing AA through drivers is insufficient.
How do you enable non-native resolutions for Nvidia cards?
Open the Nvidia control panel, go to adjust desktop size and position, enable override scaling, then create a custom resolution by entering 2560x1440 and optionally 3840x2160, testing each setting to ensure it works on your display.
