I recently upgraded from a GTX 1080 SC to a EVGA RTX 3090 FTW3. All my other components have stayed the same since the upgrade (I have an i9-9900k) but I've noticed a significant drop in performance in Minecraft of all games. I have no explaination as to why this happens which is kind of why I'm here. I don't know what could possibly be causing this. However after using the Afterburner OSD, I realized that one of the sixteen threads on my i9-9900k (usually the 12th thread) is pushed nearly to 100 while other threads are sitting at low 10s, 20s and sometimes even 0% usage. The strange thing is that I've noticed no other problems in any other games than Minecraft. So I'm beyond confused. It also doesn't matter if I do or don't have optifine or what version I'm running of the game.. its the same experience on all of them. Any help would be greatly appreciated.


Edit: Also I've completely reinstalled windows, chipset drivers, I've run DDU.. the whole 9 yards nothing has worked so far.
