Wow, the frame number problem!

The CPU is not low This year, the X4 925,5770 was just changed, and the 4G was only 40-50FPS when there were many people driving it.

Before, the configurations of 5000+(2.6, yours is still 2.8), HD4670 (much worse than 4870) and 4G were all worse than yours, and I can reach your frame number.

I think it's your hard disk, which has low rotation speed and slow file reading speed.

Also, plug-ins can affect the number of frames. I don't know what plug-in you use. Most people use bigfoot, right? I haven't used it. I don't know how many frames can be improved by disabling all Bigfoot plug-ins, but I disabled plug-ins before and can improve 20 frames.
