I re-downloaded minecraft because of a lot of world corruption and bugs that prevented me from connecting to multi, but after re-downloading, the raytracing, which used to run smoothly, became very laggy. The display chunk without raytracing used to be 45 and had no problem, but now it crashes frequently unless I set it to 20. I predicted that another re-download would fix it, which it did, but lo and behold it got worse and even laggier. Redownloading should usually fix bugs and lag, but this game seems to get worse...
