slow/lag issues

[cowboy5345]

im pretty much a noob at this but what settings are good for higher frames because on midnight club 3 i keep getting 20-40 and its pretty choppy but when my car is just sitting there the frames jump to 60+

my comp specs are
Athlon II X3 455(3.3GHZ)
8gigs ram
GeForce GTX 550 Ti EVGA 2GB Edition

Overclock the CPU, try the MTVU hack, EE timing to 2, VU cycle stealing to 2, make suer you are in hardware mode DirectX10 or 11. You have to play around with the settings to see what works. You CPU is kinda old but there is some hope.
