Sorry..english is my fourth language .He asked at what (which game(s)), does this happen.
These percentages were actually average difference from multiple games. On that Firingsquads tests 8800 GT SLI did have small winning margin on Half Life 2 (1600x1200 lost with 0.5%, 1920x1200 won with 1%, Crysis won with 25% margin at both resolutions and BioShock (won with 5% margin at both resolutions). In all other cases there was over 30% difference
Bigger wins(+50%):
Lost Planet
Company of Heroes
Oblivion
