i have an amd hd 7750 and want to play battlefield 4 on it at 1680x1020.. i downloaded the beta mantle drivers but they didnot work correctly instead i faced a hefty drop in the FPS on battlefield 3(i know it isnt mantle supported) but if it gives me mantle at the cost of loosing me directx performance then i m not willing to try it.. when is the stable release expected?
