Pimax’s prime of the road providing, the “8K” X headset, initially shipped with a max refresh charge of 75Hz for its native decision mode. At present the corporate is releasing a beta replace which pushes that as much as 90Hz. The corporate says it labored with NVIDIA to beat prior “bandwidth limitations” to allow the upper refresh charge on most GeForce RTX 30-series GPUs.
The Pimax “8K” X is the corporate’s flagship headset, and the one one able to natively displaying full decision frames on its twin three,840 × 2,160 shows. Nonetheless, when working the headset on this so-called ‘native mode’, the headset can solely accomplish that at 75Hz. Alternatively, customers can swap to an ‘upscale mode’ which accepts a pair of frames at 2,560 × 1,440, and upscales them to the headset’s full decision—this implies the picture isn’t fairly as sharp however you possibly can it run at 90Hz.
At present Pimax solely revealed to Highway to VR that the corporate is releasing a beta firmware replace for the “8K” X which can bump the headset’s refresh charge as much as 90Hz even within the ‘native mode’, giving customers each max decision and max framerate.
For now that is solely potential when utilizing the headset with Nvidia’s GeForce RTX 3070, 3080, or 3090 GPUs paired with the appropriate GPU driver model. Pimax “8K” X house owners can obtain the beta firmware replace right here and see which GPU drivers are required.Picture courtesy Pimax
Whereas the “8K” X beta firmware at the moment solely helps native mode at 90Hz on the RTX 3070, 3080, and 3090, Pimax notes, “our workforce continues to be testing and hopefully the refresh charge improve could be prolonged for the “8K” X on extra GPUs sooner or later.”
Whether or not which may embrace the RTX 3060, or a number of the higher-end 20-series GPUs, isn’t clear right now.
Pimax says that it labored immediately with Nvidia to interrupt by prior “bandwidth limitations” which prevented the headset from working at 90Hz in native mode. Certainly, the distinction in pixel throughput between upscale mode at 90Hz and native mode at 90Hz is greater than double (664 MP/s vs. 1,493 MP/s), making it clear that bandwidth turns into a problem.
Sooner refresh charges in VR make for a smoother and decrease latency view of the digital world which advantages each consolation and immersion. Excessive refresh charges are particularly necessary for ultra-wide discipline of view headsets like Pimax’ as a result of human peripheral imaginative and prescient is extra delicate to show flicker than the central a part of our imaginative and prescient.
Notice: We put the “8K” in quotes as a result of Pimax isn’t referring to the identical 8K that’s usually used to explain TVs and displays. The headset’s complete horizontal decision is the width of an 8K TV show, however that is cut up throughout every eye. Moreover, the decision peak is simply half the peak of an 8K TV show. When referring to the headset’s identify, we put “8K” in quotes to assist our readers perceive that it’s getting used in a different way than they could count on.
