At GDC 2019, Pimax today introduced two new software features designed to simplify the work of headsets. Foveated rendering (FFR) fixed and smart anti-aliasing added. Functions work for both 5K + headsets and 8K headsets.
Fixed rendering renders with lower resolution everywhere except where the user is looking. This is the same method that is used on Oculus Go and Quest stand-alone headsets. Pimax claims that it provides a 10-30% increase in productivity. Now the function works only on NVIDIA RTX GPUs, but the company is working to bring it to old cards.
Intellectual anti-aliasing is similar to asynchronous anti-aliasing from Facebook and anti-aliasing from Valve. When your GPU does not provide the proper frame rate, intelligent anti-aliasing synthetically generates every frame that is lacking due to low GPU performance. When the GPU is no longer sinking in power, the application returns to the full frame rate.
Unlike Facebook and Valve, Pimax gives users the ability to change the frequency of headset updates. Thus, the default refresh rate is 90 Hz and 80 Hz for 5K + and 8K, respectively, but users can change this figure to 72 Hz or 64 Hz.
These new features and options are aimed at simplifying the work of Pimax headsets on existing graphics processors. VRcue hopes that a combination of FFR, intelligent anti-aliasing, and the ability to use lower frame rates will improve the Pimax experience.
