#Extremely poor performance with brand new B580

Hey guys, I joined this server to gain some insight.

This is an entirely new PC build, here are the specs:
-Intel Arc B580
-Ryzen 5 5500 (no integrated graphics)
-16gb DDR4 Corsair 3200mhz
-Gigabyte A520I AC motherboard
-Crucial M.2 NVME 1TB
-Samsung 870 SSD 2TB
-Corsair CX450W power supply 80 Bronze rating
-Fresh Windows 11 install

Here's what I can rule out:
-ALL drivers for GPU, motherboard, and BIOS is latest version
-CSM disabled, all ASPM settings disabled in BIOS
-Resizable BAR set to AUTO in BIOS but Arc software says it is disabled!
-All windows settings have been gone through and entirely switched to performance enhancing options
-A whole lot of other stuff I probably can't remember at the moment

The symptoms:
-Poor performance from GPU, "3D" category is maxxed out when attempting to play a game, even on lowest settings.
-Games used for testing were Halo Infinite and Forza Horizon 5
-Not all VRAM is being utilized
-GPU frequency maxxed when running a game
-Can barely achieve 60FPS on low settings -Tons of lag, frame drops, and stuttering. CPU and RAM are not maxed out or bottlenecking in any way.

I really am not sure what to do or what the issue is. This is brand new parts and the install is a few hours old. The performance is horrific.
Is it possible that my old monitor and HDMI cord are incompatible with such new hardware/software? It is a 60HZ HDMI only 21" 1080p screen, very simple and low spec. If you want a screenshot, please specify what you want to see. Any help is appreciated! I will likely not be able to get my money back for this card as the 30 day window has passed.

This sounds like ReBAR isn't working

#

Gigabyte BIOS issues I think

Not auto on rez bar, it need to stand on on, i hade the same card with very nice performance in every game around 240 fps

Gigabyte only has Auto or Disabled.

#

I think the Ryzen 5 5500 is a PCI-Express Gen 3 part so it doesn't want to go hard

extremely stupid decision to buy brand new b580 with weak pcie 3.0 cpu and expect high fps

according on researches, intel arc gpu rely on cpu more than nvidia or amd cards. i dont know what do you want from your set up

#

and 450W is not even minimum for b580. 650 is down-line
