[PC] A possibly important bit of information about the Stutter Bug

Troubleshooting Hub Legacy Troubleshooting Legacy Motorsport Issues

I noticed that during an extremely bad stutter incident that was > 20 seconds a few moments ago that when I alt-tabbed the game would run smoothly (I have multiple screens and can see forza while alt-tabbed) and when I Tabbed back into the game it would begin stuttering again. I did this multiple times to make sure it wasn’t a one off.

That implies while it is not the current / target window the game will run smooth.

This may shed some light into what is going wrong when stuttering if the game runs smoothly when not the current window.

Manually setting all the Graphics options from Dynamic, along with limiting the FPS to 60 fixed the stuttering in my case, give it a go and see if it helps.

Negative. I’ve tried all ranges of settings from 30fps to unlocked, resolutions of 1280x720 and 25% scale. It has no effect at all. Just happens randomly.

Making sure the game bar was on and making sure that game mode is off in the game bar that you can open in game seemed to help a lot. I was doing the spa endurance race last night did 14 laps with very little issue. Still had 1-2 stutters.

I disabled all of the game mode recording and game mode itself. The issue happens about once every 7 or so laps but that still renders the game unplayable online as you can easily go from first to last during the larger stutter periods.
