LL has since removed high-res snapshots using render targets. I find this change to be favorable, as rendertargets were very finicky to get working with anti-aliasing. Also, deferred rendering uses many rendertargets that depend on screen resolution. Changing resolution every screenshot is.. not very awesome.
There is some deviation from LL's viewer. I've kept the old tiled glow pass enabled for non-deferred, as it fixes issues with tile edges truncating glow propogation. However, this does no work with deferred yet. I need to pin down why. I assume using binding one of the RenderTargets is required for deferred.
Additionally, the usage of a RenderTarget for snapshots is what prevented me from fully enabling my supersampling settings. Now that that hurdle is gone, I consider including this new setting by default to be safe enough.
And a note: Do not remove the 'tiling' variable when merging with v2 changes, as singu's glow pass is 'special'. There are other fixes absent from LL's viewer that require knowing if the render is tiled or not. (water reflections/cloud freezing)
