@wolfgrimdark - You're right, SweetFX does not take into account the ingame brightness like I thought it did. FRAPS will work better than ENB or SweetFX, but it only takes 24bit image. What can I use that will take a 32bit image AND take into account the ingame brightness?
Here is a SS comparison with K ENB Extensive and the ingame brightness turned all the way up. Notice that FRAPS is the only one that captured the ingame brightness. Too bad the image is 24bit.
ENB doesn't even capture the SweetFX settings, so it's the worst one of the 3.
