Hi guys. Just noticed something very strange today and was wondering if anyone on Windows 10, with crossfire setup and a freesync monitor could look at. This might be driver related, although not entirely sure, was hoping some of you experts could throw some ideas.
What happens is, when Frame Pacing is enabled in CCC, I get very regular frame drops every 10 seconds or so. I could happily be sat at 144fps solid, then the game/benchmark will stutter then frames drop to 60 along with my core clocks dropping to 800MHz from 1050MHz. Within a second or so, my clocks go back to were they are set and my frames jump back up to 144fps. 10 Seconds later the same will happen, fps drops to 60 or so as do my core clocks for a second or so then the core returns to 1050MHz and fps returns to 144fps again. It's really regular, happens at the same interval regardless of what I'm doing on the screen.
Have a look here at these examples, both done on a bench run of Valley, the only difference is one with Frame Pacing on and one with it off. Both tests with Freesync enabled.
This is Frame Pacing "OFF" (disregard the spikes as this was a bench run and the drops are in between the 18 different tests, as you can see the GPU clock speeds remain stable though and the fps remains up over 100 apart from the change between tests. )
And this is with Frame Pacing "ON"
As you can see, with Frame Pacing on, the charts are all over the shop. GPU usage drops to 46% every 5-10 seconds which results in fps dropping to 60 at that time, then bounces back up to where it should do. There's a 9k difference in score as to be expected.
Does this look like a Driver Issue with Windows 10 and Frame Pacing when using Crossfire? Could it be Freesync and Frame Pacing not behaving? I never had this issue on Windows 8.1, when gaming I always run Frame Pacing and Freesync as it makes things so smooth, I've never seen this regular frame drop every 10 seconds before.
