Sure...

Windows 7 32bit
CPU: AMD Phenom(tm) II X4 810 Processor
GPU: AMD Radeon 5850 with Catalyst 12.4
FPS with 50pcs design with 0.7.3 is actually now pretty decent, about 100fps.

I recently downloaded 0.7.3 and 12.4 drivers. Maybe that helped? I'll report again if I run into some issues.

Oh yeah... it just went from 1024x768 to 640 when i pressed right arrow. I assumed it already cycled and highest res. is 1024 ;).
