Hi Sith,
Not sure I agree with you. Most of us report that things are fine (or at least acceptable) if we use FLIR in CCD mode, and the drop in FPS occurs only if we switch to WHOT or BHOT IR mode. If all three were causing low FPS, I'd buy it that it's an issue of low VRAM, but it is not clear to me at all that on the same system CCD works fine, but not IR. Wouldn't understand why IR is more VRAM intensive, unless there's a bug or something like this. And to say it again, I have 4 gigs of VRAM.
