NVIDIA GeForce Now quietly starts working on Linux as the Avengers come to play
If you use or have been following NVIDIA GeForce Now, the cloud gaming platform that delivers PC titles you already own from sources such as Steam and Epic Games to a multitude of devices, the latest development seems to have emerged silently. Spotted by the team at GamingonLinux, users of Linux can now, it seems, access GeForce Now in either Chromium of Google Chrome.
Indeed, previously this tactic involved fudging user agents to make GeForce Now believe you were on a Chromebook, following the launch of the web client for Google's laptops. And it works just fine, I logged in and played some games with no issues on Ubuntu in both browsers. And just to double check, Firefox still shows an incompatible device error.

AMDGPU TMZ + HDCP Should Allow Widevine DRM To Behave Nicely With AMD Linux Systems
Coming together this year for the mainline Linux kernel was the AMDGPU Trusted Memory Zone (TMZ) capability for encrypted video memory support with Radeon GPUs. This topic was talked about at this week's XDC2020 conference.
AMDGPU TMZ prevents unauthorized applications from accessing the encrypted/trusted memory of an application. TMZ protects both reads and writes while leveraging an AES cipher. But while discrete Radeon GPUs can also support TMZ, for now the AMD Linux developers have just been focused on the capability for their APU platforms.

Zink OpenGL-On-Vulkan Seeing Some 50~100% FPS Gains
After working on getting the Zink OpenGL-over-Vulkan driver up to OpenGL 4.6 with still pending patches, former Samsung OSG engineer Mike Blumenkrantz has been making remarkable progress on the performance aspect as well.
This generic Mesa OpenGL implementation that works atop Vulkan drivers is about to see much better performance. Blumenkrantz recently commented the performance was turning out better than expected but that was for micro-benchmarks. But now with more optimizations he is achieving even better results.
