That's a standard session with enough light-based sprites. I can't do Frost Moon or anything with the Arcanum as it just freezes and I have to quit the app. Flame traps are also a no-go.I'd never seen the lag quite that bad.
Could you post a video of it in action when you get a sec?I'd never used it before, so I don't know how it operated on PC. Takes some getting used to. It did help me retrieve some excess wire from my cross-map teleporter; I hadn't been able to see the wire clearly before or reach the mistakes I made
