I'm still having issues with the Intro Movies with this patch (probably wonder movies too, but I use the intro to judge). With the original version (if I recall correctly), the video played fine, but audio cut in and out. With 1.09, it stuttered BADLY (it got like 4 frames in and then stopped for a few seconds). With 1.52, it's closer to smooth; the jumps are smaller, but still there. I remember that I've seen that wonder movies got worse, but I've tried all the options here looking at just the intro movies. SyncInput didn't help, nor MemSaver. Fraps says I'm getting about 14 FPS on the movies; the Bink player plays them at 30 fine.
The system ought to have enough horsepower; I just got it (replacing the computer for many reasons), but it's got an Athlon64x2 3800+ dual core, 2GB ram, and a NVidia 6200 graphics card. Normal resolution is 1680x1050, but the problem happens on any resolution down to 1024x768 at 16 bit color (can't force it to run any lower than that). Latest BIOS (Asus K8N-SLI motherboard), sound drivers (RealTek AC97, ALC850), and video drivers (81.95, I think; not in front of the computer right now).
Oh, and I've never turned on in-game AA; it's always been 0 whenever I look. I tried turning it on temporarily, and the clouds started moving jerkily, so I turned it back off. And I've gone through at least one full removal and reinstall since then.
Any suggestions? I'd try the low-res movies, but they're not out there. I know people don't have issues on computers with less memory and CPU, so I suspect some interaction thing (which I can hopefully set some setting for)
