I can't seem to edit my post.
I've found a resolution that did not involve crippling the 3D acceleration performance of the VM.

However, this seemed to disable VMWare tools, resulting in a bit of annoyance for certain VM functions (no clipboard sharing, no drag and drop, mouse stays confined). I also have poor network connectivity when joining boats with my host PC, yet the network performance is just fine otherwise.
So, it works, but not like it did before. Suppose I have to be thankful for that at least.
Now to hope Nexon pulls their head out of their arse and unblocks VMs, since it's quite clear bots aren't using them as the servers are still flooded with them.
