NVIDIA have a little present available for Linux fans today, with the release of the 435.17 beta driver now being available.

This is a beta driver and it includes quite the highlight with the addition of PRIME render offload support for Vulkan and OpenGL. This is where you might have your Intel GPU running most normal applications, with an NVIDIA chip then powering your games. It's usually found in Notebooks and it's been a source of annoyance for NVIDIA Notebook owners for a long time, so it's really pleasing to see proper progress like this.

It comes with some caveats though, as it needs a very up to date X.Org Server with git commits not available in a normal release yet. However, if you're on Ubuntu 19.04 or 18.04 NVIDIA have provided a PPA. There's a little additional work needed for now too, you can read more about the PRIME render offload support here.

For the rest of what's in this new driver, it has the usual assortment of bug fixes and "experimental support for runtime D3 (RTD3) power management on Turing notebook GPUs". The full changelog can be found here.

Is anyone else noticing something feeling kind of... off, when using this? I've been playing Overwatch with this feature for a few days now and it often feels like the framerate gets lower despite the game reporting that it's not dipped below 60 even once. What it feels like is almost like a lower framerate video rather than the game itself slowing down.

I have no hard numbers nor do I know how to get them, but it almost seems like the stream from the discrete card is being slowed in some way depending on the circumstances. Something just feels very off and it doesn't happen when I just boot my DE with nvidia-xrun.

Luke_NukemWell... I've been playing No Man's Sky v2.0 through Proton on the beta drivers. Nice, smooth, fast.

Laptop is an MSI GS65-Stealth RTX-2060. Also played a few games through Proton D9VK without issue too... I'm blown away...

Power use with power-management set up drops down to 7-10w for browsing etc. 7w just idling. 4-5w with screen off. Guesstimate 6-10 hours battery time depending on what I'm doing.

To get proper power-management I needed to do sudo tee /sys/bus/pci/devices/0000:01:00.0/power/control <<<auto

sorry to be a pain and thanks for your detailed descriptions so far.

is there a complete tutorial somewhere ? also am I reading this correctly in that it means logging out is not necessary ?

thanks (a bit lost today)
