Nvidia driver will offer mobile G-Sync?
The new leaks from Nvidia states that they will probably enable G-Sync on mobile and desktop displays. Some started to believe that Nvidia’s GeForce was only a business scheme after trying out this new driver. Nvidia made sure with the Alter Arriva V FPGA that the G-Sync will only work on their approved video cards and monitors.
Clearing things up with G-Sync support
If we follow up, Gamenab believes that G-Sync has a protection component named ‘CUDA’ in order to make developers create a Nvidia GPU, and Alter FPGA only exists in the G-Sync to confirm that the module is there.
It is true that CUDA is Nvidia’s language but, it was released two years before OpenCL 1.0 and DirectComputer, so we can say that one of the accusations is false. Nvidia created its own proprietary language simply because there nothing similar to it on the market back then. Gamenab continues to accuse, saying that Altera FPGA is only a DRM solution. Again, Nvidia responds by denying this and explains they built ASIC because the present monitors did not have the supporting features G-Sync needed.
The main reason why Nvidia created G-Sync as a solution for synchronizing frame display was due to the fact that you could not find any ASICs available in the market. To put it simply, a standard desktop display will not enable G-sync even while using this driver.
In spite of Gamenab’s accusations, it is important to understand that this driver is not ‘hacked’. The driver was leaked from one of Nvidia’s OEM partners, its design was only meant to enable an early version of G-sync support for mobiles. But even with all these things happening, we can be certain that mobile G-sync will be available.
Mobile G-Sync ‘ Preview
The driver was installed on an Asus G751 laptop even though it was useless for enabling G-sync on the device.
Vertical Sync or V-Sync is the classical method of preventing screen tearing while playing a game. V-Sync’s prevents half-displayed updates by locking the frame rate.
It is not easy to see the difference between G-Sync and V-Sync, but you can notice that V-sync is has a bit of jerkiness compared to G-sync which has none.
Keeping in mind that the driver is in alpha stage, in some places the frame rate jumps but still, the timing and delivery are looking better with G-Sync.
So what about the mobile support?
Since the announcement of G-Sync, Nvidia was planning to explore mobile versions too. The alpha driver presented in the leak demonstrates that the company still wants to make the support , but it is not not clear when they will be done. Just because G-Sync worked on an Asus laptop it does not mean it will work with other devices as well.
As opposed to desktop monitor, mobile displays do not have independent chips to ease timing and control of other properties.
Nvidia did not want to divulge the secret of how they will make G-Sync to work on mobile devices, but people believe they will solve the problem how the Adaptive-Sync did.
