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

Hey folks. We’ve been investigating this for a while with some help from Nvidia and have determined many of these leaks and hitches can be attributed to a bug in Aftermath that was exposed by a change in the way we render certain things. For the moment in 4.20 we will be disabling Aftermath by default ( you can still enable it manually if you need it ). The change is a simple one in Engine/Config/BaseEngine.ini to set r.gpucrashdebugging to False. I’ve confirmed that this fixes the leak (and so far in my soak the hitching) in 's project. If anyone is interested in testing this fix, make the change I mentioned then reboot your machine just to be sure, and run your projects again. You can confirm Aftermath is disabled in the log, or just by checking the state of ‘r.gpucrashdebugging’ via the console. (It should be 0). If anyone STILL sees a leak or hitching please report back as it’s likely a separate but similar. Thanks to everyone in this thread for helping us track this down!

Hi There, i see 4.20 is out now, and the release logs state this:

• New: Added support for NVIDIA Aftermath to be enabled by default.

  So, has this been disabled/fixed in the current new 4.20 release?

  Cheers!
