First of all, hi everybody, this is my first message I own a gf4 card and used to have the slowdown problem. I downloaded the new 53.03 Forceware driver (http://www.3dchipset.com/drivers/beta/nvidia/nt5/index.php) and it fixes slowdowns completely. The bad news is it generates another problem: the field appears green and black striped... Im testing different configurations but havent got any solution yet.
