Hi jrcbandit -
Out of curiosity, what system are you running the game on (Windows / Mac / Linux) and where did you download it from?
From what I can see in your screen shot, this lighting effect may be intended. Some lens flares and lighting like this is intentional. I'm going to quote Morten from another thread about weird lighting issues here:
Yeah, we hope to have fixed this issue soon. Sometimes it's kind of difficult to know if people are seeing the same thing as we do, and determining if what some people are seeing are actually bugs or if it's maybe just personal flavor pitching in. At least the way the lens flare is intended to work there are occasional "box" flares, but nothing so major as to render the effect annoying.
We know, however, that some users with Intel and ATI/AMD cards are experiencing a blooming side effect of the lens flare which is not part of the bloom from other objects in the scene. Many of these users have also mentioned a bloom/lens flare effect coming out of some characters' eyes, making them look like they have l4z0r eyes!
This issue we hope to have fixed shortly.
As far as the frame rate issue, this is a known issue and the team is working on it. We're expecting a performance patch sometime next week that will hopefully fix some of the frame rate issues, among other things.
As far as SLI, that's a bit out of my depth. I thought I read somewhere that the game doesn't currently support it, but I don't know the details or accuracy there. I'm also not sure if this is a Unity thing or not? Someone else might be able to give you more information on that. (I'm not quite the tech aficionado that some of the forum members are.)
Hope some of this information is helpful!
