Hey! I want to play some games on my Arch system via steam. But when I start a game, it uses the Intel Graphic-Processor and not the NVIDIA GPU. I can start for example Minecraft with my NVIDIA GPU when I use bumblebee (optirun). When I start Steam with optirun it starts normally, but when I start a game it immediately closes.
Systeminfos:
CPU: i7-6700HQ
GPU: NVIDIA GeForce GTX 960M
WM: i3

Needs more information, which game specifically and what terminal outputs do you get?
FWIW other options for doing more generally compatible (though not as on the fly and integrated as bumblebee) are outlined in https://wiki.archlinux.org/index.php/NVIDIA_Optimus

I tried it only with Rocket League yet. I want to play CS:GO on Linux. Which terminal outputs do you mean?
Offline
steam/rocket league while reproducing the issue, many of these crashers could also be unrelated steam runtime issues, did you try to reproduce just running on the intel card?
Offline
No, how can I do that?
Offline
Well run it without optirun?

Then the game starts and I have low frames

I experienced similar issues when attempting to use optirun and bumblebee. What you want to do is start up Steam normally (not optirun), then add a startup parameter to the games.

Ok, I have installed primus and now I have with high settings ~50 FPS but on Windows I have 120, is this normal or can I do something do gain more frames?

This is normal, primus vsyncs by default: https://wiki.archlinux.org/index.php/Bu … ble_VSYNC)
In general, since the offloading operation with bumblebee and primus is suboptimal, you could opt for one of the already linked methods or make use of the new experimental PRIME code in the latest driver https://bbs.archlinux.org/viewtopic.php?id=248796
