Mine is a 21.5 inch iMac 12,1 with a bios flashed k2100m

Big Sur was PERFECT on this (Metal ; brightness control ; transparancy)

Today I installed Monterey on it and it was super choppy.

I overrided the GPU as Nvidia Kepler, now it's recognized in system information, but there is no acceleration.

What should i do?

Thanks.

(That 2.4 Ghz i5 is actually a sandy bridge Xeon 1260L which I also upgraded.)
