Hello, I am new here and I wanted your help regarding this issue I am facing since I built my PC last year.

Computer Type: Desktop

GPU: ASUS RX 6600 8GB

CPU: Intel i5 11400F 6c/12t 2.6 GHz

Motherboard: ASRock B560M Pro4/ac+

BIOS Version: 1.60

RAM: Corsair 16GB 3200 MHz CL16

Operating System: Windows 10 22H2 version 19045.2965

GPU Drivers: AMD Adrenaline Software version 23.5.1

Description of Original Problem: I have low GPU usage and huge fps drop in games like RDR2 and FH5 in specific locations when ReBar is turned on. The interesting thing is that when I toggle ReBar off in the Adrenaline software; fps returns back to normal in those specific areas but the caveat is fps overall lowers without ReBar. I just wanted to know if this is normal behaviour or is there something I can do to fix it. Games are installed on an SSD with page file turned on. DDU has always been used before driver update. If needed I can also provide images of the problem with ReBar turned on vs turned off. This problem can be easily replicated in Appleseed Timber (RDR2).

Troubleshooting: I have updated the bios, tried GPU drivers from 22.5.1 to the latest version, have reinstalled windows but no dice. I have tried everything and looked at various forum posts here, AMD forums, etc but I have yet to come upon a solution.
