Yes I had the same initial impression when first running CPR. It does
appear fluid even at 15-20 fps. But 20fps is smoother than 10 fps and
30 is smoother than 20 fps. While a constant frame rate is an
important requisite for the illusion of smoothness, it doesn't
substitute for the glassy smoothness that comes from a constant 30-35
fps.
I went back to try unaccelerated GP2 which on my PPro200 + 3dfx +
Millenium is set to 21 fps and usually gets around a 100 PO. It
appeared much smoother than CPR. Also, the image is much clearer and
doesn't have the jagged lines at the edge of the track which makes
visiblity better. UBI F1 also gives the same impression of smoothness
with a clearer image.
Dave.
