Resizable Bar essentially broken on AMD GPUs

[andyrobbo69]

Suffering from low gpu usage and huge fps drops in games like RDR2, FH5, DOOM (2016) in specific locations when ReBar is turned on. I have updated the bios, tried numerous gpu drivers, have reinstalled windows but no dice. The interesting thing is that when ReBar is turned off; fps returns back to normal in those specific areas but the caveat is performance overall lowers without ReBar. I have scoured the internet for any fault on my end or any fixes but have yet to come upon a solution. My friends with all AMD systems have no such problems but people with Intel CPU + AMD GPU combinations appear to have the same problem. Is this normal behaviour or something can be done to fix it? Thank you!

Specs - Intel i5 11400, RX 6600, B560M, 16GB RAM

Hello andyrobbo69,

Thank you for posting on the Intel️® communities. We would be more than glad to help you with your issue.

For this problem, the best course of action is to report this issue to AMD support. This seems to be related to the graphics card and not the processor. AMD will provide you with more efficient troubleshooting.

You can also contact your motherboard manufacturer since they can provide you with the motherboard's optimal configuration for your system.

We will now close this thread. If you need any additional information, submit a new question, as this thread will no longer be monitored.
