a750 open resizable bar instead lower fps

[Timsir527]

When I don't turn on the resizable bar, the fps can reach 130~140, and the gpu usage can reach 90+, but after turning it on, the fps is left in the 70s, and the gpu usage is left 50~60.

Enabling resizable BAR on your system, featuring an AMD R5 4500 CPU, Gigabyte B550M Aorus Elite motherboard, and an ARC A750 GPU, seems to lead to a decline in performance, dropping FPS to the 70s with GPU usage at 50-60%. To address this, update BIOS and GPU drivers, check for resizable BAR support and recommendations from manufacturers, explore BIOS settings, and experiment with different configurations. If issues persist, seek guidance from community forums or customer support for your motherboard and GPU. It's crucial to find a balance that optimizes resizable BAR functionality without compromising overall system performance.

But this problem only occurs in apex legends

[Timsir527]

I found that r5 4500 only supports pcie3.0. Is this possible reason?

Hello Timsir527,

Thank you for the reply.

I tried checking the specification of ARC A750 and it supports Up to PCI Express 4.0 x16.

So checked the link below and found that Ryzen 4000 series is not listed.
