GRID data was captured running the same section of a track over a 1 minute interval for each protocol. We enabled Nvidia encoding in the Steam settings as well. The client device (measuring the frames and rendering the stream) is a Win 10 computer with an i7 6700k + GTX 1070. All tests were conducted in 1080p, with a maximum bandwidth setting of 30mbps. The games were run on a Win 10 device with an Intel G4560 + Quadro m2000. FRAPS test - Parsec versus Steam-in-home-streaming playing Tomb Raider 2013 The Testing Environment The results of the Tomb Raider 2013 test are below. The graph above combines the tests with GRID with the frame rate testing feature in Tomb Raider 2013. The spikey nature of this density curve means that there’s a much higher likelihood you’ll get frames at 16.67 milliseconds using Parsec. You can also see in the graph below that Parsec is much more likely to hit 16.67 milliseconds between each frame. FRAPS test - Parsec versus Steam-in-home-streaming playing GRID The Results - Parsec Is Much More Consistent Than Steam Streaming On Your Local Network We did not test video quality or other measures of performance. It’s important to note, we were only testing frame delivery latency and consistency. We are big fans of Steam and were expecting to just match their performance rather than way outperform them on this measure.
Again, Parsec is far more consistent than Steam in the LAN at hitting 16.67 milliseconds between each frame. Honestly, we were surprised by the results. This eliminates the hacks required with the VPN and focuses attention purely on the performance of the two products streaming capabilities.

Parsec supports LAN and WAN streaming out of the box, so naturally, we wanted to test how our software would perform versus Steam on the LAN. To make low latency gaming possible over the internet, we’ve built a ton of technology, including our own networking protocol. Consistently hitting 16.67 milliseconds is extremely important for the perception of latency and smoothness of gaming with a low latency streaming protocol, like Parsec. In that test, we demonstrated how Parsec is much more consistently hitting 16.67 milliseconds per frame for a consistent 60 FPS gaming experience over the internet. It was also the default method for hacking cloud gaming on Amazon Web Services with Steam.

This set up is your only option for accessing your gaming PC using Steam’s streaming product while you’re outside of your home. This first example is much longer than it really needs to be.We previously analyzed the performance of our game streaming product, Parsec, versus Steam-in-home-streaming + a VPN (Steam + VPN) over the internet. There are ways of dealing withįields that contain commas, but to start with, we won't worry about it. Each line is a record, and each field in the record is

It's helpful to know where Parsec fits compared to the tools usedįor parsing in other languages. Surprise that this parser library for Haskell is built around the
Parsec provides some simple parsing functions, as wellĪs functions to tie them all together. Parsec is a useful parser combinator library, with which weĬombine small parsing functions to build more sophisticated For instance, we cannot use regularĮxpressions to parse source code from most programming languages. Regular expressions are nice for many tasks, but they rapidlyīecome unwieldy, or cannot be used at all, when dealing with aĬomplex data format. Keep in mind that the Nefarius ViGEmBus is used by a good number of other applications, with the most known one being Parsec. We already learned about Haskell's supportįor regular expressions back in the section called “Regular expressions in Haskell”. The task of parsing a file, or data of various types, is a common
