fps DROP since Third Edict update (POE2)

Since the update my frames dropped from a constant 140ish to 45 and to 20 in fights. Changing any graphic options doesnt change anything at all, but direct 11 gives me up to 80 frames now in town, which doesnt matter.
I reinstalled my gpu, looked for troubleshooting with my files, updated my Windows 11 and made sure my refreshrate is still at 144 everywhere. But still there is no change. A friend of mine with almost the same setup can play at high graphics with 150+ fps as I did before the update.
If anyone knows anything that helped with the issue, pls leave a komment.
For now thx in advance.

My Setup:
Intel(R) Core(TM) i7-14700KF (3.40 GHz)
RTX 4080super
Windows11

Could you please post a DxDiag?
