[1.7.9.0] Constant Stutters Beginning Seconds After Flight Loads

ISSUE DESCRIPTION

Description of the issue: A constant high-frequency stutter in frame rate seemingly caused by a matching high-frequency stutter in the graphics queue response time occurs for the entirety of all flights, beginning a few seconds after a flight loads.

The frequency of the stutter seems proportionally relational to graphics preset - low = very slow, but still present and tangible stutter, ultra = stutter so fast it just seems to read on the FPS display as high response time/lower overall framerate. Ironically, this makes ultra one of the better experiences due to the lack of stutter, but is still not great. See below for screenshots of the FPS display at each preset and a video of the stutter beginning after the flight begins.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)? Every flight, for the entire flight.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Begin a flight with the FPS display enabled

  2. Observe a constant high-frequency stutter originating in the graphics queue a few seconds after the flight initializes

YOUR SETTINGS

If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.

Note - this was tested with a completely empty Community folder, with all remotely-relevant background apps closed completely, and after having cleared all the usual caches, streamed packages, etc.

What peripherals are you using: Turtle Beach VelocityOne Flight, Turtle Beach VelocityOne Flightstick, Axair MIAP, USB keyboard, USB mouse

[PC Only] Are you using Developer Mode or have you made any changes to it? Yes, but only after the stutter was noticed and developer mode enabled to verify/document the stutter.

[PC Only] What GPU (Graphics Card) do you use? AMD Radeon RX 7900 GRE

Same here! Unable to do a single flight

Please don’t forget to vote for bugs you’re also experiencing :slight_smile:

This issue persists after several additional troubleshooting steps, including:

  • enabling Resizable BAR (which had been previously, and now again, disabled)
  • uninstall/reinstall of the sim

Next step will be to roll back from the beta to verify that this is not an issue with my system/GPU.

Well, can’t really explain it, but they’re gone. Here’s all I did:

  • Verified the issue was still present this evening (it was)
  • Rolled back to SU4 to see if the issue would persist there (it did not)
  • Re-enrolled in SU5 beta to continue testing things now that I confirmed it wasn’t a hardware failure
  • Problem solved (???)
