Slow score tally after completing a level

[Spider-Dan]

I originally bought this game in 2009 and played through it on a WinXP PC. I had no problems with framerate or slowdown on that PC.

I recently reinstalled it on my much newer and more powerful (circa 2013) Win7 PC. I've noticed that after completing a level, the sheep tally screen is VERY slow. The following video represents the tally speed I remember:

In that video, 9 sheep are tallied in about 2 seconds. On my machine now, it's taking about 8 seconds for the same tally. I've tried both shader 2.0 and 3.0 and there's no difference.

Any suggestions?
