1. Bloody hell, that was really clever! Hats off for you

Although, what I see is only a top-left part of that window, torn diagonally, for something like 20-50 milliseconds. I would need a recording hardware plugged into the video signal chain to capture it. Also, the result might depend on double / triple buffering, VSync, Vulkan vs. DirectX, G-Sync / FreeSync and other similar settings. We are really splitting hairs here.
2. Yes, I finally noticed what you were talking about, thanks for explanation. Time to book an appointment with ophthalmologist, it seems.
3. Couldn't figure how to swap Lae'zel's shortbow with a light crossbow, but I don't think it matters much. Larian is surely getting your telemetry, so I expect them to close this loophole in the next update.
V_Ben,
Alright, the picture is pretty clear now, thank you. We are not supposed to have fun, we are only supposed to have Larian's "fun". No more questions from me.
