[Fedora25][375.26] Graphical stutter in Gnome3 and OpenGL games, on GTX950

Hi all!

This is my first post here, so yay! But, on to the problem, what happens to me is the following; whenever I’m in desktop (Gnome3) or in OpenGL games, they stutter, kind of if they had only one fps. I’m running Fedora 25, and a GTX 950, with drivers 375.26.

With gnome it happens, for example, when entering the “panel mode” (or whatever it’s called), when you press the win key or point the mouse at the top-left screen corner. I can feel it too when opening/closing applications such as nautilus or gedit. Watching videos in youtube works fine, but watching them with Totem Player stutters too. I believe gnome uses OpenGL to render itself? Or am I wrong?

Then, playing OpenGL games (eg CS:GO) has the same issue too, even on the menus. But when playing games with Vulkan (eg Dota2), they work smooth and boombastic.

I’ve already searched for solutions but quite didn’t cut it, so here’s a list of things I’ve tried:

  • nvidia-xconfig --no-composite
  • rm xorg.conf
  • Use a backup xorg.conf
  • Maximum performance in powermizer

And of course have disabled nouveau:

  • Added “blacklist nouveau” to /etc/modprobe.d/blacklist.conf
  • Added “rd.driver.blacklist=nouveau” to GRUB_CMDLINE_LINUX in /etc/sysconfig/grub
  • Removed xorg-x11-drv-nouveau package
  • Generated initramfs

Thanks a lot beforehand!
