I have FS2004 and had a XFXGforce 2 - 64mb card and when I used high settings to low I would get this short stop in motion of my A/C. It happened about every 3 seconds. My frame rate would drop a little and then resume around 20. After reading a lot I decided to go with a PNY Gforce 5700 Ultra 128mb card 475/900 (Effective) speed. I did the same ranges as before and the same is happening. The only change I notice is the weather is awsome in high mode. I still get the pause in the low modes. Any suggestions?
