IE games ran at locked framerates due to the use of sprites (same as Diablo 2)
120Hz monitor and a CRT that does 120Hz as well
Used to it from FPS games I guess, you need at least 125FPS in cod4 (250 optimal) at competitive level.
My Titan Quest runs at mostly over 120FPS but when it sometimes drops below 100 there's a noticeable visual slowdown even on a lesser refresh rate.
I highly doubt it's even humanly possible to detect a difference unless there's some very fast motion on-screen. In fact most of the time unless there's sufficiently fast motion you'd just be drawing the same thing again, so there really is
no difference, detectable or otherwise. Try playing BG2 in GemRB some time, it can get to hundreds of FPS, but you'd never notice because for most of those frames there's literally not a single pixel on screen that's changed
. With a game like this I'd be surprised if you could even notice the difference between 30fps and 60fps most of the time.
I'm not saying that there is no difference in general, or that you're making it up when you say you can notice it (I have on very rare occasions wished I could play WoW at 120fps myself), just that in this circumstance
I'm highly skeptical that it would make any difference.
Also if there are pre-made animations (not sure if that's something we'll be seeing) it wouldn't make much sense to render them at a frame rate that can only be displayed on a monitor that costs more than most people would spend on an entire computer.
