Nvidia’s Latest GPU Drivers Fix High Power Consumption Issue Among Other Things
Just a few days ago, Nvidia released their latest GeForce 361.43 WHQL driver. As previously reported, it gets rid of some of the BSOD issues plaguing Windows 10 users as well as introduce some general fixes for all users. Among these fixes is one that is perhaps one of the biggest issues that has been plaguing Maxwell GPUs for quite a while now.
Users reported that G-Sync and non-G-Sync displays with high refresh rates were causing an incredibly high amount of power draw from their systems. The power consumption only increased as the refresh rates increased. This issue now seems to be fixed after the latest update.
Another big improvement for all Nvidia GPUs concerns OpenGL and Virtual Reality, further down the road. Nvidia has introduced a custom OpenGL extension, “GL_NVX_linked_gpu_multicast,” that can accelerate headset rendering and boost performance by up to 1.7x. The company states that Autodesk VRED Professional 2016 SR1-SP4 has already integrated the capability.
“With the driver in the new multicast mode, all OpenGL operations that are not related to the extension are broadcast to all GPUs in the SLI group,” the GPU manufacturer claims.
SLI is important to VR because it allows the system to dedicate one GPU to each eye, rather than rendering right-left-right-left in quick succession. What this new Nvidia extension does is allow the system to upload the same scene to two different graphics cards simultaneously without incurring additional overhead.
Nvidia has also included additional documentation and code samples with DesignWorks VR and GameWorks VR SDK for developers to look at and understand how the function works.
