Help needed - Gaming on a A10 8770E mini PC

Hello everyone. I am aware this is an old CPU. It can play quite a few games on Windows 10 though, once the boot sequence finished and it finished loading all stuff it needed to load.

I have searched for information to see if I can use this system with Linux for some light gaming. I did manage to install Bazzite, and my initial experience with DOTA 2 was good (it runs better than on Windows).

It went downhill after that. Doom 3 is a no go (need to check the Lutris Linux port), Borderlands 1 GOTY Enhanced, abysmal performance. These two worked ok on Windows.

Are R7 graphics supported for Linux gaming? I read on some posts that it is, others that it isn't, others that say "it depends". Perhaps Bazzite is not the best distro for this machine? Does anyone have a system similar to mine who could perhaps recommend me a distro or some insight on configuration?

Specs:

HP 705 G3 Mini PC

A10 8770e AM4 CPU

16GB DDR4 ram

512gb NVME

1 TB HDD (can replace with an SSD if it will change anything)

Any suggestions would be welcome.
