Hi. I hope I'm writing this in the right place. Not sure if this issue is in particular version of Sonic Worlds, because Chrono Adventure is unaffected. When I play Axiom, ATS or BTS, it staggers harshly (it reduces to below 20 FPS for one second) every several seconds and discourages me thus to play these games any further. I thought it is not device dependant, as it staggers in walkthrough of Razor & Zenon in YT too, until I saw Redhotsonic's video - 60 FPS intact. Is there any fix or workaround for this problem? I tried in XP and 7, both fullscreen and window mode, changed refresh rates... but it didn't work.
