Update: I also tried VMWare Player but I also ran into the same problem I had with VirtualBox. The DirectX drivers are installed but not the needed OpenGL drivers, although I installed VMWare tools and its Virtualbox equivalent on both VMs. Do I have to use the VMWare/Virtualbox drivers or can I use a generic driver from Microsoft? Attached is TSL'S self-diagnostics output from both Virtualbox and VMWare. Also, the only mod I'm running is TSLRCM.
