Significant performance drop after changing GUI Scale [Iris 1.8.0-beta.3+1.21.1] [NF only!]
Reference to https://discord.com/channels/774352792659820594/1268783719121031310/1274243774494539788
As described in the previous alpha builds, once the user changes the GUI Scale setting, the current session will be suffering a massive performance decrease until the client has been restarted.
From what I observed this primarily affects the use of shader packs, ComplementaryReimagined_r5.2.2 + EuphoriaPatches_1.3.2 being used as an example however not exclusive to it. Also this happens only, I believe, when a shader pack is currently active during the settings change.
For good measure:

Update:
Now running NeoForge 21.1.65 with Sodium 0.6.0 beta 2, Iris 1.8.0 beta 5 and Euphoria Patcher 1.4.1 r5.3 I discovered:
Pressing F11 twice in order to exit and reenter full screen does reset the aforementioned lowered framerate by some magical power in heaven
The issue in of itself persists however and remains exclusive to the NeoForge mod loader from the testing I have done
I am also in the process of trying out various different settings changes in order to potentially make even greater and weirder finding on the matter
As before, testing is done with a shader pack currently active
Specifically Complementary Reimagined R5.3 + EP
However not all is conclusive as even the full screen "fix" in fact does not appear to completely resolve the issue but instead lower the "penalty" applied
Pre-F11 used twice
Post
And then of course the gui scale stuff
The difference between Pre-F11 and Post can however be much more substantial as shown with a personally configured modpack and shader pack combo
No need for the gui scale screenshot as this time it's the same value, hovering around 125 fps rather than the previous 165
