Description Turgut Kalfaoglu 2016-08-09 05:18:07 UTC
Description of problem:

Running games under wine-1.9.15 leads to small pauses in the game, every two seconds. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install a game under wine or crossoffice, such as World of Warcraft
2. Try the game
3. During game play, a small pause is felt every two seconds.

Additional info:
I am told that this is due to the kernel scheduling. 
The real-time kernel should be able to fix this; however, Bumblebee does not work with the RT-kernel, because the new NVIDIA drivers refuse to be compiled under the RT-kernel. Hence, Fedora should include the precompiled drivers and the RT-kernel.

This bug is a huge bucket of nope.  I'm sorry, but none of the things you're asking for are something that will be done.

If you have a suspected issue with the scheduler, contacting upstream is the best solution.
