Panorama uses SB
SB = Shadow Buffer? Just guessing. Think someone made performance tests but I can not find any figures. From what I 'heard' SNAP is only slower when it fails to program MTTRs correctly. But would be glad if anyone can provide measurement results. All cards in my systems are supported by SNAP in accelerated mode (yes old cards like X300) and I do not have an up to date Single Monitor setup to test myself.
