Extremely bad shaders performance

Ive recently updated from 1.21.1 to 1.21.7 All shaders that i have used previoulsy now cause a meltdown in my gpu for some reason All mods im using are DH, Soudium and Iris, nothing more On 1.21.1 i have: 50-55 celsius with DH off 65-70 celsius with DH enabled On 1.21.7 on the other hand: 63-68 with DH off instant 83+ with DH enabled and low fps making the game unplayable is it just me or is it a common issue

dh render distance was set to 3k, the same for both verions shader settings were also the same the problem isnt in the high gpu usage itself, but rather it increasing dramatically with a game version change, without tweaking any graphics settings

MC 1.21.6 and 1.21.7 are known to have bad performance even with just vanilla MC Performace drop is expected, wait for Mojang to fix the performance hopefully soon Or play on older MC version, 1.20.1, 1.21.1 or 1.21.4

You're talking about GPU temps? 83°c is not very extreme for a gpu What kind of fps are you getting and are you using the same mods, world and settings on both versions?

i know that but my specific gpu is capped at 83 if the temp goes above it the fans instantly go to 100% and the performance drops to the floor i have no idea how to disable this it might be hardcoded into the bios or something no idea nevertheless a 20 degree increase caused by changing a game version isnt normal either maybe 10/15fps, and yes the same mods (with appropriate versions), worlds and settings

Could you recreate this with screenshots and send your specs? And with the newest nightly version and all that
