--- Comment #8 from Vorobyov Anton phoenix@mail.ru 2008-05-03 13:27:53 --- To be honest i don't know what HDR and bloom is, but difference is obvious:
1) Most of reflecting parts of ships became more shiny when lit with any projector 2) E.g. lasers got 'glow' effect around turrets, and most of light-emitting devices too.
I don't see any of mentioned effects when HDR is off.
So, it seems that HDR worked on my GF8600GT mobile (acer 5920)
