I have just installed a new graphics card (radeon rx 9250) and it seems to be working ok....but...its slower than my original graphics card ( radeon 7000 ) and when i look closer the agp seems to be switched off...How do I switch it on for 4x or 8x agp. Ive tried switching it on but when i reboot my pc it reverts back to the old setting. Do I have to change the bios setiings?? I have tried this but Im not sure what Im looking for Can anyone help??
