4.19 & 4.20 Editor & Packaged Games Have Hangs/Hiccups Constantly

[IronicParadox]

385.69 is the last driver, that does not have the. With this driver installed, those, who experienced hitches and memory leak in test project or any other projects, should not have those problems.

But that is not what it is about.

There is a screw-up, that broke the engine for all newer drivers(read all as 390.65 and 397.64. I did not check the others). somewhere between 4.18.1 and 4.19.0 and that needs more or less urgent hotfixing, as I see it at least.

I’d be grateful for any pointers, which change in particular is to blame.

Also, what about the same occurring on iOS, as mentioned by @-H ?

I don’t know… I’ve seen issues, with the newer drivers, in other games/engines. Things like hitching, stutter and microstutter, that all go away when I roll back to 385.69. I’m really starting to think this is an Nvidia driver and not an Epic.

As for the iOS, there isn’t enough information to really judge it by. -H might just have a bad loop or something with the game. It might be related, it might not be related. This would be one of those test questions where the answer would be D) Not enough information. He’d need to try your sample map, drop the loop count to something more reasonable for a mobile platform, like 10, then perform the same test. Otherwise, his iOS symptoms are anecdotal.
