In 2022.2, we added support for DLSS 2.2 and a Deep Learning Supersampling menu to Visualization > Realtime Antialiasing. Select from these options:
Use DLSS to upscale and antialias a rendered image with little performance impact and potentially better render performance, taking a lower resolution image and producing an image that looks higher resolution from it. This is very useful for VR content.
An NVIDIA RTX GPU with a 471.68 or later driver is recommended for DLSS. The Deep Learning Supersampling option will be greyed out if your graphics card and driver don't meet the requirements.
