Re-enabled the beta channel of the Oculus software last night and ver 27 does seem to fix the flashing. But performance seems a bit lower than it was with v.26. Normally I’d have to disable ASW because there would be so much wobbles/tearing but I didn’t need to do that in v.26 but I had to again in v.27.
But that could just have been a fluke good performance the one time I played with v.26.
