Observer : GPU lockups (AMD) :(
dvd commented on 10 January 2019 at 6:17 pm UTC

(A bit off topic: In my personal and very subjective experience xfce is just as fat as kde. Just uglier and has worse programs. On systems that are old and cannot run the 'modern' desktops, i usually install some sort *box or lxde, those seem faster.)

dvd : ahah, you couldn't resist ;) (I agree with you but that's kinda OT ;)

@mirv : Hmm, so even the daily PPAs are not recent enough according to you ?

Thanks for the replies !

I love Observer and keep tabs on the Steam forums.

I've played Observer on both RX580 and GTX1080Ti in KDE Plasma 5, compositing enabled, dual monitors (just played on one though).

This game heavily favors Nvidia cards/proprietary drivers and has always been a Russian roulette situation with AMD cards. It ran fine on my RX580 and Mesa 17.3.5-ish, after some major bugs in earlier Mesa versions were fixed that prevented the game from running at all.

Still, many report issues even today with fresh kernels and Mesa versions, even Nvidia users suffer from various problems. Also, the game isn't all that optimized so it can run pretty slow on really strong machines.

Lots of threads about this in the Steam forums, you've probably seen most of them. I'm afraid there is no simple answer. The game is what it is and there will probably not be any further development or bug fixing.

@dpanter : yeah, I guess, this is due to the nature of the game (adventure game which is probably just meant to be completed once ?). I thought it ran very decently in 1080p/high/Vsync off on my low end RX 560, but GPU lockups just prevent from playing at all after one hour or two.

I'll try again in 6 months or so ;) I really cannot picture myself using NVIDIA cards again -- except if they make visible efforts on the desktop side. (performance of 2D apps / DEs).

Am I supposed to file a bug on the Mesa bugtracker against a crash happening in a specific scene in a specific game ?

Cheers

BTW, except if you explicitly forbade KWin to disable compositing (or created a custom rule), compositing was disabled when running this game. You can check by using the "media" keys of your keyboard (raise/lower the volume) and see if there is a fade in/out animation

Cheers !

As I use Gentoo, I don't pay attention to PPAs. Sorry for the confusion there. Sticking to mesa 18.2.x or 18.3 should be fine. Not sure which llvm version goes with that right now - 7, I think? Someone can correct me.

OT: Completed the game back in the Launch week with no issues, back then on my nvidia GTX 1070. While there was some stuttering at the beginning of new locations, it ran smooth after and with good framerates @1440p for me

Maybe try this fix for Dying Light, another mega troublesome game for Mesa.
