<div dir="ltr">on a other note, if GPU support is the end goal for MOSES team, it should be noted that Bullet also can do GPU support and even multi-threaded cpu support, as it stands right now its only single thread for Bulletsim, though it can be loaded into a separate thread removed from the simulator heartbeat, it should also be noted that very little effort has gone into fully optimizing what Bullet could potentially do in OpenSimulator. I do kind of wonder why the choice to not improve this effort instead of trying to re-invent the wheel so to speak with yet another platform that ultimately is not all that much better than Bullet in the end and potentially not cross platform. I must admit my interest will be very limited if I am required to use MIAB and likely would not do much testing myself if that is the case, also I would have absolutely no interest at all if it turns out to not have cross platform support though I am not sure that is true.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Mar 18, 2015 at 10:42 PM, Michael Emory Cerquoni <span dir="ltr"><<a href="mailto:nebadon2025@gmail.com" target="_blank">nebadon2025@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">GPU is not required for PhysX there is a cpu level it can operate at as well, and while GPu support is good, I would also be surprised if OpenSimulator could actually fully utilize a GPU before mono would barf anyway, mono can only handle so much threading and even offloading all of that processing to the GPU, all that data ultimately has to flow back through mono / C# / OpenSim HTTP server and I suspect there will be a huge bottleneck there that would not allow for much more performance than the CPU itself could handle anyway, there would likely be some improvement though, the question is does that warrant the inclusion of an expensive GPU in a server, its going to draw a lot more power, and will not make a lot of sense in a standard data center style setup with 1U rack servers, expanding rack size increases costs quite a lot, the question is does that increased cost benefit performance enough to justify it, the only way to really find out is to try, I wonder if InWorldz does any GPu offloading for their implementation of PhysX, i suspect they do not but would be great to know for sure.<br></div><div class="gmail_extra"><div><div class="h5"><br><div class="gmail_quote">On Wed, Mar 18, 2015 at 5:15 PM, David Saunders <span dir="ltr"><<a href="mailto:abitar.com@gmail.com" target="_blank">abitar.com@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I know there be allot of grid interested in trying out the new physics when offer. <div><br></div><div>THe only big drawback of people adopting the PhysX is that relies on a GPU to do its processing and not sure if you run more then one engine on a machine.</div><div><br></div><div>I am sure smaller grids and self hosters would love it. </div><div><br></div><div>But do correct me, I not looked into PhysX since last year. </div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div>On Wed, Mar 18, 2015 at 4:42 PM, Shaun T.
