NVENC on NX

[lg]

hello.

I’m the author of http://lg.io/2015/07/05/revised-and-much-faster-run-your-own-highend-cloud-gaming-service-on-ec2.html. Basically using Steam In-Home Streaming to play games that are actively rendered on AWS EC2 GPU machines and streaming the video to my laptop.

i’d like to get NVENC working with NX such that I can update the instructions and not require Steam anymore. The server is a G2 GPU instance on AWS which virtualizes an Nvidia GRID K520 card. The client is the new Macbook running 10.11.3.

Problem is, I don’t know how to enable it on NX. I installed NX5 and turned on the checkbox to use acceleration and tried forcing H.264 in the server settings, but when looking at the display settings, it just says it’s just using VP8. I shouldn’t need to buy the AVC pack, right? (since that’s for H.264 software rendering). Note that Steam is able to properly activate NVENC (and use NVFBC), so it should be working on NX too…

Where are the logs for this and what should i do to debug? what should i look for in the logs too?

thanks!

Hi Larry,

at the moment NoMachine only uses the NVENC capabilities on cards of the Maxwell generation. That is because NoMachine relies on some encoder features that are not fully supported in the previous Kepler generation, and that is the case of the K520 card virtualized in the G2 instance.

However we are already working on a special mode that can work with Kepler cards without glitches, and we are going to enable NVENC on such cards in the next release.
