The script for the camera angle/side-scrolling mod makes my computer go haywire, Steam shits itself and I can't get into the game through that launcher. Not sure what the problem is but I've tried multiple versions of the script on different versions of JABIA.
I've noticed that with the lowest camera angle the game does chug a bit, but this is usually resolved by turning down view distance. But even that doesn't fully solve the problem. I would recommend, and hopefully this is easy to implement, a system by which zooming-in to (or close to) a ground-level perspective will also lower the view distance, automatically. I also get the distinct impression that a lot that's "fogged out" by the view distance or behind a wall gets rendered anyway, because a lot of times the game will chug in a low view even when there's nothing going on. The whole point of fog distance is to reduce GPU load by not rendering crap that's far away... but that's probably a fairly substantive change to make.
But a more flexible camera would be a terrific feature, I've had to reload more than once after being unable to see/target the guy(s) that shoot up my mercs.
The view/fog distance is already tied to the angle (you sometimes can see this in certain areas while the zoom-in is in progress). The view distance you set in the options is associated with this and does not apply to top-down view (otherwise you'd not see anything when zooming out far). Objects that are completely in fog are of course not rendered, otherwise we'd not use fog at all (except for art purposes). Additionally, with low view distance settings, small objects are not rendered anymore once you're far away, even if they're not fogged. However, what we'd really need is a LOD system, which we introduced for the textures of the ground system with the first patches. Providing a geometry LOD system is in my opinion out of reach, as it'd require a rework of basically all art assets (please keep in mind that we introduced the low camera angles in a patch due to customer request).
