Any time I open my inventory, open machine inventories, or even hit escape, its been taking a second or two longer than what it should. I opened the debug pie (f3+shift) and tested it that way and came to the conclusion that it was my render that continues to spike when opening interfaces of any sort. I followed with trying it again but in a different location, restarting the pack, restarting my computer, and re-downloading the pack. Each of these resulted in the same conclusion. I don't use optifine, and I have a well built computer identical to a friend, who has not encountered this issue. If anyone can help that would be swell. Thanks!
