So Robert Taylor posted an interesting blurb about UE4 and the Switch:




The link that he posted from UE describes two variables for the engine, r.GTSyncType and rhi.SyncSlackMS. I'm not an expert in UE (like @masagrator), but are these variables something that could be edited in an ini for games that may have not known about them? Or are they console commands of the engine that can only be changed upon exporting the games from the engine?

Iirc this works practically only in 30 FPS, in 60 difference is practically non existent. And this is not as easy as just enabling it. You need to put some functions in correct places for this to take effect.
This setting can be easily found in UE4 documentation about latency, so dunno how you can miss it when trying to find how to fix latency.

But never tested this for 30 FPS games, so I am not sure if what I'm saying is correct.

If those options don't require manual implementations of some functions, then Yes. But executable will search for it only if executable has this line adapted in binary and only under fixed categories.

Thanks for explaining! I knew you'd come through with some good info.
