I noticed this issue recently. A thread in the official Skyrim forums prompted me to investigate further. Basically, the intended action and resulting effect are not in sync. For example, I enter a dungeon, sneak, and approach someone with my bow. Pull back on the bow and release. I hear the release sound, but the arrow disappears for about 5 seconds. Then I hear it hit the target. When it happens, it's extremely obvious. For me, it's most apparent with the bow. How do I know it's a FPS limiter causing this? The OP in this thread did some testing. FWIW, I'm using the FPS limiter here (iCCC ENB as part of the STEP guide). Has anyone else seen abnormal delays in casting spells, bow/arrow, viewing inventory textures, etc? Curious what the fix is besides running with vsync on and FPS limiter disabled (results in poor framerate for me and jerky game behavior). My rig, in case it matters: i7 950 @ 4ghz 12gb GSKILL Ripjaws Nvidia GTX 470 in SLI
