I found this on reddit:

https://www.reddit.com/r/Windows10/comments/3oatuw/those_of_you_gaming_on_windows_10_heres_how_i/

It DOES NOT help me, but I thought I wouls ask Skuzzy what he thought of the reasoning behind it. It doesn't make sense to me that Microsoft would attempt to control the refresh rate of monitors from within Windows, but they being the same people that made Vista, and now Windows 10 . . .
If you like the Sick Puppy Custom Sound Pack the please consider contributing for future updates by sending a months dues to Hitech Creations for account "Chalenge." Every little bit helps.

I was free of this for a short time but it's back. I suspect this has already been stated but in case it hasn't, this problem is not limited to Windows 10. I am using W7 Ultimate and have the same problem. Perhaps the causes are different but the symptoms on the same. I see it on every map, at all locations, and in all GVs and planes. I see no correlation with location, sounds, action, or vehicle/plane.

Gonna go into MSI AB and check the box to disable ULPS in AMD driver and see if this stops then (Fiji GPU's support ULPS).....................

Update:

Set this up and tested in game.......didn't stop the screen pauses so it's not related to any AMD driver\GPU hardware level power control going awry.

At this time I am satisfied w\ all this as now I know that this isn't tied to AHIII client at all............
This is an issue between the OS and AMD driver stack when AHIII client is started using Dx11 API.
If anything this is demonstrating just how good AHIII is making use of my FuryX graphics card's post processing shader capabilities thru Dx11 vs Dx9 to perform all the graphics rendering\AA work which is offloading my graphics card's GPU to the point that the GPU is running out of work and isn't needed so it drops down to 0% activity until it receives draw calls from the game thru the OS to start back up doing work....sometimes this isn't happening fast enough to keep the graphics frame buffer filled w\ finished frames to display so the screen will momentarily pause when the buffer is emptied until the GPU can catch back up since most of the graphics work that the CPU did in times past has been offloaded to the GPU w\ AHIII so this is appearing to be a communication\timing issue that is between the OS's Dx11 API and AMD's drivers (path thru which the game instructions are communicated to the graphics card's GPU) so this would have to be rectified by AMD thru driver stack tuning for the AHIII client thru Dx11.........uh huh...........

As far as the rest goes this is in the bag now so until something else changes (maybe Vulkan...?  :D) I'll just have to go w\ AHIII under Dx9.

Sorry Skuzzy but just liken me to being the 1 kid who keeps asking "why"............................

Not claiming to understand this completely, but the same problem exists with Nvidia hardware and drivers.

Also, if it is not related to the AH3 client, wouldn't it be a common problem with other games and DX11?  Is it?

Did some offline testing today and found that turning off shadows eliminated my stutters.
For some reason the shadows appear to be more taxing on my system, than turning environment map to all.
I was on the deck while doing my tests.

Shadows on: 40fps and game stuttered badly.
Shadows off: 60fps and game was smooth as silk.

If your frame rate is less than the vertical refresh rate of your monitor, it is not uncommon to get stutters as the game surges and slows with the frame rate changes.

If your frame rate never drops below the vertical refresh rate, and you are getting stutters, it is, usually a different reason.

Skuzzy, are we any closer to finding the stutter source? :headscratch:

I do not know.  We have some thoughts.  They are all guesses though.  Without being able to reproduce the problem it makes it damn difficult to figure what is causing it.

Did the stutters I experience show up in the .ahf films or only the YouTube videos I posted?

HiTech has those Ack-Ack. I know most of the films he has looked at has not shown anything one thing to be the issue.  It is very random.

Not sure if its related, but I see odd distortions underneath the radio chat bar (especially if terrain is behind it) and through the prop. It appears to be map related, some have it some don't. Its like horizontal wash distortion.

I also had odd stutters on a couple of FSO maps (the North Africa/Italy one), where if I were in certain locations I would experience them.

Is it possible to issue a debug addon for the client to log parts of the session Hitech thinks causes this? I still get them from time to time in DX11 sessions, DX9 is steady.

Well, this is very disappointing. I had these stutters when AH3 first was released, but switching back to the DX9 version seemed to fix the issue.

No longer. My machine has not been deliberately altered (see PC specs link in signature), but this past week or so, my FPS number drops from 59-60 down into the low single digits about two or three times every minute. The screen pretty much freezes into immobility. I've tried all the suggested fixes listed here in the forums that I can find, but no joy. The game is simply not playable for me now.

I think that I may have found how to avoid stutters: turn AH filming off, turn skin downloads off, turn other plane's skins off. All three together seems to work, but the biggest gain appears to have been from turning off filming.

I was having a lot of stutters and micro freezes last night. Logged out checked the task manager and found a windows component pulling up to 20% of my cpu. closed it down and went back in game and it was smooth as silk. Stupid windows  :furious
