Newest patch causes game to use all of my memory

since the last patch borderlands has been unplayable. i load in and within a minute my computers memory is all used up and i drop to 4fps, lasts about 30 seconds then will go back up for a minute then repeats every few minutes. This is the first problem ive had playing BL3 and have ran it smoothly on high settings since launch.

im using an i7-4790k - 4ghz with 16gb ram
and my video card is a nvidia gtx-980.

does gearbox even respond to any tech support forum posts?
