Linux: performances issues, crashes
|Assignee:||Frédéric Bertolus||% Done:|
|Target version:||Ongoing issues|
I have some severe performances troubles sometimes, which usually leads to a game crash. After a moment playing, the game can start to lag heavily. I've noticed that using the "J" key to pass days is often involved in the crashes.
These issues appears when i launch the game via Steam, but also when i launch it with the command line. I've tried also the beta, which seemed to be a bit worse about rendering performances.
Besides this, the game is very dark (i know it's intentional, which is great!) and i need to push the gamma at max. No lights from my ship, since i understood there should be one. And the engine sound is almost always clipping (probably due to the mem being saturated).
I've joined the crashes directories and the savegame, even if i don't think the later is related to the issues.
Here is the output i have in the command line when it crashes (stable version, but the beta one is almost the same):
Pooling OS allocations (pool size: 1408 MB, maximum allocations: 9502).

And finally, my specs:

Intel HD Graphics 530 (Skylake GT2); Version OpenGL : 3.0
I hope all this will help you! Et si vous avez besoin, je suis français, donc on peut affiner les choses dans notre langue maternelle!

I just tried quickly (launch the game, load a save, fly a bit around) with all the graphic settings off or lowest. No real luck, apparently, it still lag a bit. I'll have to test it in the long term, though, and i'll keep you in touch with this.
But i must say that previously, my graphic settings were already at the lowest, appart from the texture one which was medium. I had the AA thingy on too (the second button, not the 2x), and the antialiasing, i think. I had the cracking sound again, by the way; i'm no expert, but i think that linux sound server can be a bit tricky sometimes, maybe it's a lead.
Anyway, thanks for the answer, i hope the next builds will help with this somehow...
