[14.22] Low FPS with low GPU usage on Linux

[elmassao]

Hi everyone!
I have a i7 920 with 6GB DDR3 RAM and GTX750Ti (378.09) running Ubuntu (kernel 4.4.0-59).
The game run always with 60UPS but <25FPS. It does not matters which game mode I play or what map I load, even on a fresh start the game runs slow.
I have tried to change driver's version, every single graphic option enabled/disabled, vertical sync, atlas caching, etc... my FPS never hits 25. The logs says that the graphic card is recognized and, from the utility, it is used less than 4%.
I will not send a zipped map because it is useless, as I said, the problem appears everywhere.

Thank you for your patience, any help would be appreciated.

Could it be this one: viewtopic.php?f=7&t=3619?

I have only one screen not rotated and now I tried with compositing feature disabled but it does not change.
My video drivers are at the last version but even with some older version the problem persists.
I made a screen of the GPU stats window where is shown the usage.

I notice only now: is it common that the gui rendering took 60% of the rendering time? Or had I misunderstood those numbers?

No, it is not, but the game renderer is way too high as well especially considering that there is nothing fancy like steam or smoke yet, so it seems to be a general graphics card performance problem, even running it on some onboard graphics we would see better results. Since you tried the usual stuff already, I would test if other games have the same issue.

I can run Dota2, Counter Strike, Rust, Minecraft (heavy modded), Kerbal Space Program (heavy modded), OpenTTD (with graphic mods) and a variety of other games without problems so far.
I have tried the standalone version of Factorio and the Steam version with/without the Overlay: same results.

With great pleasure I can say that today, with the version 15.1, all problems are gone! We still don't know why, but it doesn't matter: it's great anyway to play Factorio.
Thanks to every one!
