bfgminer wont detect GPU?

[dustofdeath]

so thought to check it out instead of cgminer - but when i start it up i get hashrate in bytes - or basically 0.
Device Manager shows no devices aswell - does the bat file need some special commands for gpu?

Code:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
bfgminer.exe --scrypt -o stratum+tcp://eu.ltcrabbit.com:3333 -u x.max -p 1212 -o stratum+tcp://us.ltcrabbit.com:3333 -u x.max -p 1212 -I 13

im astounded that this has been read 252 times but no one replied, You see this is a question I was trying to ask myself, as I want to see if BFGminer is better than cgminer -  Should I re-post it? Or no one literally knows the answer

Driver is wrong

try cgminer.

But CGminer works perfectly how can the driver be wrong, only trying BFGminer to see if its more stable or capable than cgminer
