So I just upgrade virtualbox from 5.1.22 (working fine for 3d gaming) to the newest 5.1.24. So I set it up, re-installed Guest Additions, and now games wont play. My virtual machine is XP, so I'm wondering if anyone has had/having the same problems and knows of a fix? I haven't posted at the official VB forum because you need to provide loads of work stuff to create an account.
