Overdrive on S2240M

Hi,
I recently purchased a Dell S2240M. I really love its glossy panel and its color. Unfortunately, the display shows quite a bit of overdrive. I couldn't find any way to disable Overdrive in the OSD. Does Dell plan on releasing a new drivers soon to fix this overdrive issue? It's quite noticeable in games. I really want to like this monitor, it's a fabulous display. Can you fix the overdrive problem soon? Or should I return it?
