Question regarding CPU compatiblity

[duke2]

Have there been any changes since 3.0 that require a certain instruction set that older CPU's may not have? We're getting a crash on save on some of the older machines (not crash on render) so I don't think this is the reason, but I just want to rule it out.

maybe you could try setting to scanline renderer before saving to see if that`s the cause.

I believe the only new feature in V-Ray 3.0 which requires specific CPU instructions sets is Embree but as far as I know we developed it to automatically turn off if the CPU doesn't have that sets.
Since Emree is totally render-time features we doubt that it is involved into those crashes but you may try to disable it just in case.

Like anthonyh suggested, would be useful to know if it only crashes when V-Ray is assigned as a render engine.
