With a new update just round the corner, we thought we’d let you know about one of the changes to expect – FBX has been updated to use the latest version of the NVidia encoder that is provided by NVidia’s SDK 9.0.
What’s new?
If you are using any NVidia graphics card that supports NVENC encoding (GTX 6xx or higher and RTX 20xx), then you should see some performance improvements if you have selected an NVidia encoder that does not end in ‘MFT’.
If your NVidia graphics card is specifically one with a Turing GPU (RTX 20xx), then you should also see improvements to image quality courtesy of an additional option that is now available in FBX’s Video settings – Psycho Visual Tuning. (Since this option is exclusively for RTX 20xx users, it will be hidden for others users)
What is Psycho Visual Tuning?
Psycho Visual Tuning enables encoder options that optimize the use of bitrate for increased perceived visual quality, especially in situations with high motion, at the cost of increased GPU utilization. This means some quality that is hard for humans to perceive is sacrificed to improve the quality of what can actually be perceived. In practice, this should make things like fine text and grass look sharper, although at times it can degrade some other things.
Note – Windows 7 and older don’t support the DirectX features required to take advantage of the latest NVENC encoder so will continue to use the previous version of the NVENC encoder instead, meaning only Windows 8 and Windows 10 users will see the benefit of this update.
