Will look into this to see if setting t.maxFPS to 120 and then to 60 will give any different result.
By the way is there a way to get GetSupportedRefreshRates in Unreal, I saw that there is support on Android for this but doesn’t look like there is support in Win64. My thinking was if this is a intel Arc driver issue that it can only set MaxFPS to a supported refreshrate.
I’ll ask the infra team what exact P4 CL version of 5.5 that was integrated into our code. But we have a source build and we maintain this ourselves.
