I'm running Quern on Linux Mint 18.2 Cinnamon 64-bit with an I7 CPU and a GTX 1050 Ti GPU. Twice I have had sessions with reasonable frame rates of 30 fps but often its down at 5 fps.

The two sessions at 30 fps locked up (one after a few minutes game play the other after maybe 20 minutes). After a hard reboot I restart the game and I get 5 fps. Nothing seems particularly odd if I monitor temperatures or loads.

Other games and benchmarks run at 50 fps on similar settings. eg 720p or 1080p

Also the loading screen takes a long time (many minutes) with freezes in the progress wheel and sound.

The Linux Mint install is very fresh and the NVIDIA driver version is 375.66.

I'm puzzled as to what to look at next.

Hey! Can you test the game on the same system but different OS or Nvidia driver version? We did most of the testing on Ubuntu. I let our programmer know about the issue and I hope he can come up with something useful!

There seems to be a bug in Cinnamon that causes low fps in Unity based games in fullscreen - so a quick fix should be to run the game in windowed mode.

I'm trying it on Ubuntu Unity 16.04 with NVIDIA driver 384.9 and so far I'm getting reasonable frame rates at 720p. I haven't played long enough to test the crashes/lockups.

Unity makes me grumpy, what about Linux Mint MATE or KDE? I have a second hard drive partition for distro hopping.

I have this same issue. I only get SLIGHTLY faster FPS on low versus ultra. I have a Ryzen 1400 with an RX560 4 gig on a BIOSTAR X370GTN with 8 gigs ram.

It is not the horsepower, because I wouldn't see such a small difference in FPS between low and ultra if that was the case.

When will this be fixed?


Mine has low frame rates even in windowed mode.

It is the same slow speed windowed or not for me.

Hey! Unfortunately enough, the majority of these issues are caused and solved by the developers of the engine we use (we are on Unity). But! The good news is that we decided to update the engine under the game, so the currently live 1.2.0 version of the game is running on a newer version of Unity. We experienced better performance on Linux, so this will hopefully help with this issue.

Anyways, sorry for slacking on this forum!

I do not see a 1.2.0 version here on GOG for linux, just for windows.

Just download the newest version of Quern for linux. I did and now it works great. Maybe could be a bit more efficient but I am only using an rx560 and I am running on high settings with no blur. It actually looks pretty good. For some reason the first area, where you start the game, is the lowest frame rate. But that area is incredibly small and you're not there often.


What happened to the intro credits? It just goes straight to the start screen now when I play it.

Thank you for fixing it. I gave you a good initial review even though I haven't finished.

Um, have you thought of making a flying version of these games? A cross between pilot wing 64 and Quern would be interesting for a second game. Doesn't need the aerial challenges of pilot wings 64, but adding free world flying like that along with using flying to solve puzzles would be interesting combination. If you are going to do that the world should be quite large. Maybe the person could play as a ghost and that would explain the ability to fly?
