fps halved at certain places for no reason
Why does this sudden fps drop happen for no particular reason? I notice it happens more frequently upon entering a new instance that requires loading.
And why is it fixed when I do these steps? 1 - Set Shadow Quality: Off 2 - Click Apply Display Settings 3 - Click Revert I want to understand what causes it, I want to prevent it from happening. I know these quick steps fixes it for the moment, but it will be bound to happen again. Last edited by Xarick on Jan 28, 2016, 10:08:47 AM Last bumped on Mar 20, 2016, 6:28:26 PM

This seems weirdly related to your latency. What networking mode are you using, Deterministic Lockstep or Predictive?
What happens with vsync turned off? | |
I'm using Lockstep (auto). I don't like to play with vsync off as the video card is uber noisy, but I'm trying vsync off for a while today to see if the issue happens in this mode.
EDIT: I just turned Vsync off, and the fps which was at normal 59-63 fps went down to 22-26. I'm at the Grand Arena level. In the small dark corridors, the fps is 22-26, in the arenas, the fps is over 100. EDIT 2: The trick with turning shadows off, then reverting changes didn't fix this. Seems that the trick only works with vsync on. Last edited by Xarick on Jan 29, 2016, 12:12:52 PM

Hi again. Yesterday I played with vsync off and it is also susceptible to the same fps drop. I had it as low as 22 fps, though it is harder to find the right spot in the area. To find exactly where it triggers the fps drop, I had to move the character around in very small steps to find where the fps drops. And it drops massively, from a steady 144 fps to a steady 26 fps.
I went further and investigated CPU and GPU usage during these occurences. CPU usage is higher, ~19% and GPU usage is nearly none when I am in the spot causing 26 fps. CPU usage is lower, ~12% and GPU usage is much higher when I am in the spot with 144 fps. | |
BUMP.

I have submitted a driver report issue to AMD with the following description:
