At first everything was fine after about 4-5 days ive noticed some heavy frame drop when opening inventory. Ill go from like 130-140fps to 100. After a few hours it will start to drop to like 10. Im doing my best to figure out what the cause is. I do notice its only when the texture pack is running. Ive tried using the lesser qualities of the pack. But im still getting a heavy frame drop. Any ideas or recomendations?
