I think its currently hard to make a matrice of this, as we are in alpha (everything might change between versions, as we have seen with the latest issue with tetriary integrated GPUs).
Testing all of these is really hard for developers as there are thousands of GPUs and myriad of combinations:
which is exactly what we are doing So its just a matter of making noise if there are some issues with a GPU.
There however should be a warning tag related to integrated graphics cards and tetriary graphic chips on laptops, Before ones first Download that is. And maybe a warning (that can be turned off) which popup ever time you start interface, that this is alpha software and might crash, cause stress and etc. Its nowhere near production readiness.
If you have an ** AMD/Intel integrated graphics chip, expect issues. ** (this applies for most games too)
Even Tertiary integrated graphics chips that run on laptops also run this risk as their drivers are diverged from the main-line driver lines.
If you got the above, and aint got issues now: do expect them later on during the alpha and beta stage. What seems to be stable so far is actual GPU cards on Desktop configurations (this is for both mac and pc)
If however your gpu worked, and it suddenly stops, do make noise: but expect a fixes not to be immediate…
There is a post on this: https://alphas.highfidelity.io/t/current-minimum-graphics-driver-support/4964
However what I can say straight away:
Do not expect Intel HD 3000 or below to work, Especially if using OSX. Its highly unstable, and frames are pulled down until your LODs are at 0. Unless you are used to sitting around in blackness while everyone else is a cardboard cutout.
If you pull up LOD levels you will eventually snow crash (similar to what issues @infinitecircuit had with his mobile gpu) . Most complains I’ve seen so far are usually due to people using Intel HD 3000 or older versions.
This includes most Macbooks Pros that are not retina prior to early 2013 (of which most are probably using as the ones with the oomp are the most expensive of them or any other laptop). In the jist of it, if you computer is running CPU made in late-2012, with integrated graphics, you should be in the clear.
HD 4000 have issues as not all supported features have been unlocked by drivers (this also varies per operating systems)
Some may have some luck with HD 4000s, but with those you might be pushing it slightly.
We have to remember that alot of the work usually for graphics card stability for applications is the driver developers. Since we are in alpha, its not very high in the priority for them to get stuff working here. So stability might come with driver versions, might not.
