We have discussed adding GPU acceleration to guacd in the past in order to improve performance, but no one has had a chance to work on it, yet. It's also a bit of a corner-case, and has some constraints that decrease the value of it. There aren't a lot of people who are doing high-performance graphics rendering that need that kind of power, and guacd does a perfectly fine job with most workloads using just a CPU. There's also limitations on how many FPS a browser will actually render (might 30-60, I think - at least, this has been the case in the past), and pushing guacd so that it will go beyond that won't make much difference if the clients themselves can't actually display it. If you're wanting to work on it you're definitely welcome to - the contribution would be welcome and the support would be positive. -Nick --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@guacamole.apache.org For additional commands, e-mail: user-h...@guacamole.apache.org
