Performance of Radeon HD7750 / R7 250E

Hi,

I have the impression there's some performance problem with my Radeon R7 250E with the radeonsi drivers (all values set to default) at 1920×1080. It has quite low framerates. I ran Phoronix Test Suite with the "gaming-free" test suite and these are the results: https://openbenchmarking.org/result/150 … NITIAL1927 (look there too for system info). Compared to this https://openbenchmarking.org/result/110 … MDRADEON57 there's quite a big difference. In The Talos Principle I only get about 15 to 20 fps. I think the graphic card should be a little bit faster …

Any hints where to start?

Re: Performance of Radeon HD7750 / R7 250E

That systeminfo suggests your system has 2 videocards : radeon 7750 and a R7 250E .
Perhaps the test used the slowest of those 2 cards ?

Please post lspci -k so we can be sure how many cards you got.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

The R7 250E is a rebranded Radeon HD 7750, thus it reports both names.
