Unless J's laptop is one of those e-waste machines form Dell or HP, he should be able to allocate system memory as video memory for integrated graphics in the BIOS. But if it does have dedicated graphics, then, yeah; it is that it is for the most part.
But with that said, I'm not going to be the one ask too many questions about J's laptop since I've never played this game with MSI Afterburner to determine this game's system requirements; mainly because I'm sitting relatively pretty with a 9900K, 32GBs of RAM and a 2080 Ti and I haven't seen the 'multiple arms' bug in 0.8b-1. My actual guess is that some people might have a CPU limitation, but I'm a bit too busy at the moment to under-clock my system to have that be more than a guess at the moment.
Also, I feel as though talking about tech stuff might confuse the mods, which isn't very difficult to do.
