Changed my bios just to play yet cheaters just walked casualy into the game

so just to play the game took me a while to work out and after i got it i had changed my BIOS settings which seemes a bit invasive to begin with but after researching the reasons why i was overjoyed that the develpoers where going to such levels to remove cheaters, HOWEVER, i have so far been shot through brick walls, had guys SNIPE me with pistols, and  in recon while crouched they seem to know exactly where i am and exactly when im about to poke my head around the corner, almsot like they can see me THROUGH THE **bleep** WALL. now ive playe BF from 1942 through to 6 didnt go bf 1 2042 and 2142 BF1 and BF5 just stuck with the straight and normal bf series, had my fair share of cheaters I was into COD for a while but the cheating there was so bad i came over to BF which had much less, but this version (6) is probably the worst ive seen so far, and hoestly, i know its just the BETA but i probably wont buy if the cheaters are just taking over and the reporting system HAS NEVER WORKED. makes the game no fun at all when you die respawn and some Ahole has you locked as you come back in, there are literally people posting videos to youtube of their hacking successes in THIS game. fix the game EA!!!
