ATi Radeon issues

[Matt Morgan]

I just switched my son's computer to one that has a Radeon 5450. A low-end
card, but still it should be better than his old computer's Intel GMA 2500.
It's running the radeon open source driver and performance in minecraft
(the only app that's relevant) is worse than before.

I couldn't just take the video card and put it in his old computer--it's a
small form-factor with no slots.

This is Fedora 25, like it was before. The new computer has the same
processor as the old, though less RAM (5GB v. 8GB--unfortunately I was not
able to swap it over).

I see lots of conflicting info online about whether the fglrx driver works
on newer kernels, and I don't want to do anything time-consuming to get it
to work. Is it easier than I think? Should I just buy a cheap NVIDIA card,
or will that be a hassle too? Or is the RAM the issue?

All advice welcome. Thanks!
Matt

Check which driver is being used:

|lspci -nnk | grep -i vga -A3|

I think you need to play with the DPM (dynamic power management) settings of the card

Try setting the power_dpm_state to performance and the power_dpm_force_performance_level
to high

There is a tool available in github to do this and to set up a service in systemd as
well:
