Ever since the Java 1.21.5 update came out, I have noticed a severe FPS drop compared to the previous version. I used to get perfect frame rate in servers and single player but now my GPU is being taxed to almost 100% and my device gets very hot. I use a M2 MacBook Air. On 1.21.4, the GPU at the same resolution would idle at around 20-30% used, now it idles at 40-50% and 80-90% in servers when previously it idled at 20-30% and I had no heat issues then. I can not imagine that this new version is significantly more GPU intensive than the last version, at least not to this certain extent. The graphics look the same as the last version. Please fix this problem in the upcoming 1.21.6 update. I currently so no improvement in the Snapshot 3 1.21.6 version. I am going to use 1.21.4 from now on until this gets fixed.
Environment
The Java version 1.21.5 version seems to for no reason tax the GPU up to 60-90% very easily even at low resolutions. Even powerful machines have this problem.
