<div dir="ltr"><div>Hi,<br><br></div>It should do hardware rendering in all cases. If you're connecting the GUI to the EGL pvserver though the rendering can switch from being done on the client vs. being done on the server. You can control where the rendering is being done in your settings under the Render View by setting the Remote Render Threshold. <br><div><br></div><div>Also, what kind of dataset do you have? It's possible that the dataset type can only be rendered with a single process.</div><div><br></div><div>Best,</div><div>Andy</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 24, 2017 at 7:11 AM, Bruce D'Amora <span dir="ltr"><<a href="mailto:damora@us.ibm.com" target="_blank">damora@us.ibm.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><font size="2" face="sans-serif">using 384.61 driver.

software rendering for surface, wireframe, outline, points? Rendering in
those modes works, but when I switch to volume rendering it crashes. I
wonder if I'm just switching to H/W rendering when I switch to volume mode
