Straightforward question. Please download beta2 if you have not aleady done so (the corresponding feature is broken in beta1 and earlier), open settings.cfg in an editor and try both options, zero or one. They affect the way glancing works when you're using the smart camera (I'm not telling what they do exactly to avoid creating a bias towards one or the other). Come back here and say which variant you like better.
(Apparently, "0" alone is not a legal poll option here...)
It should have an immediate effect on all three glance keys, you don't have to wait for the round to end if you entered it at the console. Oh, it's a clientside option, changing it on the server has no effect.
I hate 1
I just downloaded the new beta after convincing from Luci, and when I opened it, the glance was the first thing I noticed. I much prefer 0, 1 was distracting. I'm not sure if it's due to the fact that I'm used to old one, or if I actually prefer it over the new. All I know is that I spent the first 5 mins I had it open, trying to figure out the console code for it. I just couldn't play with 1. 0's much better.
I should probably vote now. At first I thought 0 was better, it was what I was used to. But for maze maps like I've got on the Crack Pipe, 1 is really nice. So now I'm used to 1 and it's really helpful.
