Is there a way to get full-screen supersampling in Release 256?

Yes. Release 256 drivers do fix the implementation of Transparency Antialiasing (TRAA) and now offer up to 25% performance improvements with TRAA enabled. However, since some of our gaming really enthusiasts liked the full-screen supersampling, we have created a tool for users that allows them to enable 2x, 4x, and 8x full-screen supersampling. You can download the tool "NVIDIA SSAA.exe" from the File Attachments section below.
