The first thing I’d recommend is updating your system so you have the latest kernel, etc.
I believe that Basic Graphics Mode adds nomodeset to the kernel command line. For 3d acceleration to work, you need to remove it. You can do that temporarily in the grub menu, or use something like:
grubby --remove-args="nomodeset" --update-kernel=DEFAULT
If it boots successfully, you can repeat the command with ALL to make it apply to future kernels.
Those flags are for much older GPUs, and would have no effect for you.
