I call shenanigans. Sure, you can make a calculation of the expected time that the token will return, but if a station drops the token and/or the active monitor station dies the calculation will be wrong. High utilization and reliability were great features of token ring back when Ethernet hubs and half duplex connections were common, but Ethernet switches and full duplex were the final nail in the coffin for token ring LAN.

In deployment situations where token ring is already prevalent, a cost/benefit analysis must be made as to whether it's worth maintaining the old network or moving to ethernet as token ring vendors dry up. Also, anyone considering deploying token ring in a completely new rollout should have their head examined.

I play at 1024x768 with most if not all detail settings on high, 2 or 4x FSAA, and a decent level of anisotropic filtering. It plays fine to me, no stuttering or noticable framerate drops.
