I think if that were the case this would instead become notorious as a sub-HD, non-v-sync'd compilation. Well, if the v-sync actively lowered FPS, I can't remember that being the case on PC but then most reasonably modern PCs can easily do 60 FPS+ reliably on many games.You see, I'm disinclined to believe they would have. I think High Voltage just wanted to go for 60fps, no matter what.
Oh well, they got my money either way...
