[posila][0.17.23] Microstutter

[Coffee2Code]

Some microstuttering going on, it used to be smooth as butter.

Here's a video showing the microstutter: https://www.youtube.com/watch?v=iwsLirf30I4

Can't be the hardware either, VSync on/off no difference.

dxgi-presentation-model=flip(-discard) seems to fix the stutter

dxgi-presentation-model=flip-discard
fixed it (not perfect but significantly improved) here as well. Running Windows 10, with windowed g-sync enabled if that matters. I'm not sure where this issue crept back in, but I believe it was more recently.

...but this should not be required to prevent microstutters on a default Factorio installation, right? I wonder what is causing the issue...

Its not buttery smooth but playable.

I actually wasn't able to play anymore as the stuttering gave me a migraine

Might be related to 69022, with the difference being what happens to the surface during blitting (if it keeps the previous content or if it gets blacked out). Notably, this issue is on nVidia hardware, while 69022 might be on AMD/ATI (I can't say for certain, since OP never provided that information, but I get the same issue and am on AMD hardware).

Thanks for the report.

As of 0.17.46, dxgi-presentation-model defaults to flip-discard on Windows 8 or higher. Additionally, in 0.17.48 there will be graphics option to toggle between flip and copy.
