I’ve had the chance to test it in MSFS and IL2 a little bit and it’s really solved my issues.
With MSFS, if I fly GA where I can expect good performance, I’ll go with 120hz and lock at 1/3 of the fps and it’s so smooth now, I never have stutters anymore. I did a test flight with the headwind a330 which used to give a lot of stutters and with 90hz mode combined with 1/3 of fps I was perfectly smooth too, it’s brilliant.
You should certainly try it. Make sure to opt for the beta to get access to that setting.
