I'll admit I saw these at some point, but when I reinstalled all my FSO stuff last year, I saw the "mjn.mixael hi-res cbanims" link with the FSPort and didn't realize that this pack was higher res and more recent (what I get for doing manual installs I guess). If you want an up-to-date fsport, you kind of have to look around the forums to make sure you have the most recent applicable assets, and I somehow missed that these were newer.
I don't know how to check the in-game frame rate, but all the cb_starmap01-15 ones are playing twice as fast as the ones in tango_hi3_fs1.vp (I used a stop watch...). I opened up all the missions in the tech room real quick just to check, and I couldn't find a starmap one that didn't display at what appeared to be double framerate. I didn't notice any of the others displaying this behavior, but I missed these for two years, so I could have missed another bugged one also. Using a recent nightly, for what it's worth.
I truly can't tell if the text in the techanim style ones is moving more quickly than retail or not since I'm looking for it, but it'd be trivial if it were. They look great and the actually ships/weapons don't seem to be doing their thing any more quickly.
