<p>Hi all,<br>
</p>
<p>the two ridiculously expensive and high-end graphics cards
mentioned by Luke sound like complete overkill. Surely reading and
preparing the geodata for 3D display (from data providers, via
storage, on the CPU?) would be the bigger performance/usability
issue of the 3D views, right? I am sure that for reasonable
reasons QGIS would choke waaaay earlier than what those cards
would be capable of. The potential benefit of those cards for QGIS
3D definitely is not worth paying *1200-2500€* extra.<br>
</p>
<p>Martin/Jean, is there any change that you could provide a more
detailed specification of the hardware and software requirements
for QGIS 3D? It comes up again and again and I've just been
searching again without success. I step up to add it to the QGIS
documentation in early November.<br>
</p>
<p>Esri provides for example infos on the required OpenGL version
and extensions on
<a class="moz-txt-link-freetext"

<p>E.g.: What is the minimum amount of GPU RAM necessary? How does
it scale with more complex 3D scenes and what happens if there is
not enough RAM? Does it get slow (maybe with a message) or does it
crash? Which renderer does it use on which platforms (I guess
always OpenGL?). Which OpenGL version is needed? Which extensions
are needed? Could missing extensions get logged prominently to the
user to avoid the "my 3D canvas is white/blank" issue (I guess
that is the reason) that often comes up? Which features depend on
which extensions and what happens if they are not available?</p>
<p>All the best, Hannes<br>

<div>Hey Luke</div>

<div>Low end graphics cards should work fine as well. If your
coworker could not run 3D on his laptop, it could have been
some other problem - it would be good to have more details
(hardware spec, operating system, in what way things did not
work) so that we can fix such issues. For example, my laptop
has 2GB of GPU memory and things work just fine. So both of
the suggested graphics cards should give you much more power
for QGIS 3D than you would normally need.</div>
