How is the rest of your system? RAM, Processor, etc? I dont remember if I have the 7600 or the 7800 but I run G3 and can almost max out the settings. But I also have a good system backing it up. I havent had any experience with aerofly but I figured G3 was the bigger hog when it came to running graphics (at least thats what I hear by all the cmplaints). I know smoke is demanding on the processor because all the calculations that have to be done to simulate all the particle movements. The 7600 is a good card and sould run well but if smoke is still a problem it may be other factors in the system. Im just speculating, you could have a kickin machine that just needs a video update and if thats the case then you wont have a problem with the 7600.
