Question CSM problem with gpu

[Daniyal_4]

I have Asus TUF h310m motherboard. recently I installed a r9 270x 4gb oc edition into the motherboard. However, on the bootup, it says that the vga card is not supportd by UEFI driver and the pc boots up in CSM mode even if i turn it off.
I want to know how to fix this problem OR i can just leave it that way if the CSM mode doesnt effect the performance of my pc.
Additional INFO if it helps:
i3 8100
corsair vengeance lpx 8gb ddr4

Do you have the latest BIOS installed for your board? A 270X certainly should be UEFI compliant...

Even if it won't/can't be for some reason, it's not going to impact the "performance" of your system.
Slightly slower boot time (typically) and some limitations in terms of drive sizes/partitions, but nothing that's going to impact the day to day 'feel' of your system.
