Actually thinking back on it that may have been a little bit of misinformation as it’s been quite a long time since I tried to 5 box from one rig. My current setup consists of 3 rigs and 3 monitors running a total of 5 accounts; I use X-keys with a Vetra switch and multiplexer along with HotkeyNet to bring everything together. But back when I first tried 5 boxing I wanted to make sure I would enjoy it enough before I outlaid on the major gear so I simply purchased two 20” widescreen monitors to supplement my existing 24” widescreen. I ran all 3 with 5 accounts from one rig using extended desktop. Being the gamer I am I really wanted reasonable frame rates on my slaves without losing too much in the way of detail (especially spell detail and distance) so I did a lot of research into the pitfalls of using extended desktop/duel view etc with DirectX apps. One of the major issues that came up was the positioning of the apps across the monitors, and this was where I confused myself the other week when I replied to that post. Whilst it is true that any amount of overlap will cause a decrease in your frame rate, it will not affect it any where near as much as having one of your game windows sitting partly between two monitors, even if it’s only by 1 pixel.

I apologies for that confusion, I was simply trying to target as many issues as possible for the OP of that thread to help him solve his issue. I do still make sure that neither of the windows on my rigs overlap, and this does help a little with the overall frame rate (I have them locked at 30 maxfps and 30 maxbkfps which both windows run consistently with all but shadow detail on full). If you play around with it let me know if you notice any difference, I would be curious to see your own results on this.

Hope that clears things up
