Performance Regression [GTX 750 Ti] [390.12]

GPU Unix Graphics Linux
#1

When I upgrade from the 387.34 driver to the 390.12 driver, I notice a drop in performance in Gnome 3 when pressing the [super] key, which toggles Gnome 3’s overview mode.

Steps to Reproduce:

  1. Upgrade from 387.34 to 390.12
  2. Log into Gnome 3
  3. Press the [super] key
  4. Notice choppy window animation

When I downgrade back to 387.34, the animation becomes smooth again.

I installed the 390.25 driver, and toggling overview mode is smooth. The problem appears to be fixed.

#3

Allow me to jump in here. It seems like this issue is not entirely fixed. I am on Mint 18.3 and yes, window spread is smooth on 387.34 and 390.25.

However, performance while browsing in Opera severely decreases after updating the driver from 387.34 to 390.25.

  • When switching between tabs, there's a delay while the tab is loaded.
  • Scrolling (e.g. on Facebook or https://retropie.org.uk) is choppy.
  • Videos on YouTube are choppy for a few seconds until the system seems to "catch up".

None of these issues occur on 387.34.

I have made a video showing cycling through tabs:
